Glossary

Key terms you will encounter during your citizenship by descent application.

1

1948 CaseItalylegal: A judicial route to Italian citizenship recognition when the line passes through a woman who had a child before January 1, 1948 — the day the Italian Constitution took effect. Law 555/1912 gave citizenship by birth to the child of an Italian father, and the Constitutional Court did not strike that provision down until sentenza 30/1983; for births before the 1948 line a consulate or comune will not recognize the claim, so it has to be brought before a judge. It is NOT filed in Rome, despite what most guides say. Venue is set by statute, not chosen: D.L. 13/2017 art. 4 co. 5 assigns a claimant living abroad to the specialised immigration section — these sit at the ordinary tribunals in Court-of-Appeal seats — by the comune of birth of the Italian father, mother or grandparent, for proceedings begun from 22 June 2022. Older guidance says Rome because that was where these cases concentrated before the rule changed.

2

27th AmendmentIrelandlegal: The 2004 constitutional amendment (effective January 1, 2005) that changed Irish birthright citizenship to require at least one parent to be an Irish or British citizen, or a legal resident, for children born on the island of Ireland.

A

AIREItalyprocess: Anagrafe degli Italiani Residenti all'Estero — the register of Italian citizens resident abroad. Art. 1 of Law 470/1988 keeps it at the comune and makes it part of the national ANPR register; once recognized, you enrol through the Italian consulate with jurisdiction over where you live.
Anchor ancestorCanadaprocess: The furthest-back Canadian ancestor in your chain — the person born in Canada, naturalized in Canada, or covered by one of the 1947-era paragraphs. Note the third route is narrower than "ordinarily resident" alone suggests: s. 3(1)(m) requires the person to have been a British subject ordinarily resident in Canada on January 1, 1947.
Anyakönyvi kivonatHungarydocument: Hungarian civil registry extract (birth, marriage, or death certificate). Issued by the anyakönyvi hivatal (civil registry office) that holds the register — a Hungarian office only where the place is inside Hungary today. A Hungarian-issued extract needs no authentication, and the citizenship authority checks Hungarian registers ex officio. A birth registered in territory ceded after 1920 comes from that country's civil registry instead. For a document issued in another EU Member State — Slovakia, Romania, Croatia, Slovenia and Austria among them — Regulation (EU) 2016/1191 art. 4 abolishes legalisation and the apostille entirely, and a multilingual standard form may remove the translation too (art. 7 covers birth and marriage, but not divorce). Outside the EU, §14(5) a) of Act LV of 1993 sets diplomatic legalisation as the residual rule, yielding to any treaty or directly applicable EU act. Confirm with the post serving your consular district, naming the issuing country, before paying for anything.
AORCanadaprocess: Acknowledgement of Receipt — a letter from IRCC confirming they have received your citizenship certificate application. Processing times for receiving an AOR vary.
Apostilledocument: A certificate that authenticates a document for international use under the Hague Convention. In the US, you get it from the Secretary of State of the issuing state.
Art. 116(2) GGGermanylegal: Article 116(2) of Germany's Basic Law: a right to restitution of German citizenship for those formally deprived of it on political, racial or religious grounds between 30 January 1933 and 8 May 1945, and their descendants ("und ihre Abkömmlinge"). No application deadline; no fee. Deprivation is the test: someone who was persecuted and emigrated but was never formally stripped of citizenship is not an Art. 116(2) case — that is §15 StAG, a separate entitlement with its own form set. The two are easy to confuse because BVA names them almost identically.
Article 12Italylegal: Article 12, second paragraph, of Law 555/1912. Its text made unemancipated minor children of a person who lost Italian citizenship become foreigners only where two conditions were met together: they shared residence with the parent exercising parental authority AND they acquired a foreign citizenship. Administrative practice read it as an automatic loss on the parent's naturalization, which is the historical basis of every 'minor issue' rejection.

B

BeibehaltungsgenehmigungGermanylegal: A retention permit that ALLOWED a German citizen to naturalize abroad without losing German citizenship under §25 StAG. It no longer exists: the 2024 reform repealed §25 with effect from 27 June 2024, and the consolidated Act now contains no Beibehaltung provision at all — since nothing is lost by acquiring another nationality, nothing needs retaining. It still matters historically. If your German ancestor held a Beibehaltungsgenehmigung before naturalizing, §25 never took their citizenship and the descent chain may be unbroken, so it is worth looking for in the family papers.
Bill C-3Canadalegal: An Act to amend the Citizenship Act (2025), S.C. 2025, c. 5 — the citation of the amending Act itself; R.S.C. 1985, c. C-29 is the Citizenship Act it amends. Assented to November 20, 2025. Its s. 7 leaves commencement to an order of the Governor in Council, and IRCC gives that date as December 15, 2025. It removed the first-generation limit for people born or adopted outside Canada BEFORE that date, and for births and adoptions on or after it replaced the limit with the two-part test in the new s. 3(3).
BVAGermanygovernment: Bundesverwaltungsamt, Germany's Federal Administrative Office. Its competence turns on where you live, not on the type of claim: BVA's own guidance is that for people living permanently outside Germany «ist allein das Bundesverwaltungsamt zuständig», while anyone resident in Germany applies to the citizenship authority for their own municipality or district, and BVA transfers a file if an applicant moves to Germany mid-procedure. So for descent applicants abroad — who this site is written for — BVA decides Feststellung, §5 declarations and Art. 116(2) restitution alike, with no consulate-by-jurisdiction split as in Italy. BVA's head office is in Cologne, which is the address citizenship files go to.

C

C-Filedocument: The complete naturalization case file held by USCIS. Contains the Certificate of Arrival, Petition for Naturalization, Oath of Allegiance, and Certificate of Naturalization.
Certidão de nascimentoPortugaldocument: Portuguese birth certificate — the primary document establishing a qualifying ancestor's Portuguese identity. Obtained from the civil registry (conservatória) in the ancestor's birth town in Portugal, or from the Conservatória dos Registos Centrais in Lisbon. Request a certidão completa (full-text copy), not a summary.
Certificate of Arrivaldocument: A document verifying an immigrant's arrival in the United States. Issued as part of the naturalization process and found in the C-File.
Certificate of Naturalizationdocument: The official document issued to a person who has become a U.S. citizen through naturalization. Lists the date citizenship was granted, which is key to Italian jure sanguinis eligibility.
Certificate of renunciationCanadadocument: The document the Minister must issue under Citizenship Act s. 9(3) when a renunciation application under s. 9 of the current Act is approved. A foreign naturalisation certificate is not one, though the two are easily confused. Under s. 9(3) the person ceases to be a citizen at the end of the day the certificate is issued, unless the certificate names a later day.
CIPLE A2Portugaldocument: Certificado Inicial de Português Língua Estrangeira — the Portuguese language exam at A2 (basic) level, set by CAPLE. It is the usual way grandchild-route applicants prove the language limb of ligação efetiva; the law itself names a list of accepted proofs (Regulamento da Nacionalidade art. 25.º n.º 2) rather than a CEFR level. CAPLE runs three sessions a year worldwide (May, July, November), but each US centre offers only some of them — in 2026 Washington DC had all three, Boston and Berkeley had May and November, and Newark had May only. Registration closes 21 days before a session's first exam date; CAPLE publishes no figure for how quickly places fill.
CIT 0001Canadadocument: IRCC's application form for a citizenship certificate (proof of citizenship). The live version is labelled "Last updated: August 2026". IRCC publishes the form itself as "Application for a Citizenship Certificate" — the longer "for Adults and Minors ... under Section 3" is the title of the guide that accompanies it. One form covers adults and minors alike. It is the Section 3 PROOF application, and it is the wrong instrument for a person adopted by a Canadian, who needs a grant under s. 5.1 instead.
CIT 0014Canadadocument: The companion document checklist that must be included with a CIT 0001 application.
CIT 0555Canadadocument: IRCC form "How to calculate physical presence in Canada for a Canadian parent" (CIT 0555) — the instrument for evidencing the 1,095-day total. Needed only where the substantial-connection test actually arises. Appendix F of the CIT 0001 guide sends you past it if you were born in Canada, are replacing a certificate, have a Canadian parent who was born in Canada or was granted citizenship, or have a Crown-servant parent or grandparent.
Citizenship certificateCanadadocument: Official document proving Canadian citizenship, issued by IRCC. Applied for using form CIT 0001.
ComuneItalygovernment: The Italian municipality (town hall). You request Italian vital records directly from the Ufficio di Stato Civile of the relevant comune.
CONEdocument: Certificate of Non-Existence of Naturalization — a letter from USCIS confirming that no naturalization record exists for a person. Required when your Italian ancestor never naturalized.
Conservatória dos Registos CentraisPortugalgovernment: The central civil registry office in Lisbon (CRC) — part of IRN — which holds exclusive competence over nationality registration. Every file joins one queue and is analysed by entry date within its legal ground, so how you file does not change your position: a consular post is only an intermediary registry, and no route is faster than another. The IRN's standing priority covers only minors born abroad to a Portuguese parent who have no other nationality and remain undocumented. Portugal publishes no processing-time target, though Newark's consulate advises that the CRC is currently taking more than a year — a floor, not a range.
Constitutional vs legislative claimItalylegal: Two distinct routes to Italian citizenship. A legislative claim is the administrative application to a consulate or comune under the citizenship law as it stands — Law 91/1992, including the Art. 3-bis restriction added by Decree-Law 36/2025 and converted by Law 74/2025. A constitutional claim is brought before a judge and rests on a rule the Constitutional Court has held unconstitutional, typically the pre-1948 gender bar. They have different decision-makers, different evidence and different timelines.
Consulategovernment: A diplomatic office that handles citizenship services for its nationals abroad. For Italian citizenship, you submit your application to the Italian consulate that has jurisdiction over your U.S. state of residence.
Corte di CassazioneItalylegal: Italy's Supreme Court of Cassation, the highest court for civil and criminal matters. It does not retry facts — it rules on how the law should be interpreted and applied.

D

Decreto TajaniItalylegal: Nickname for Decree-Law 36 of 28 March 2025, converted with amendments by Law 74 of 23 May 2025 and named after Foreign Minister Antonio Tajani. It inserted Article 3-bis into Law 91/1992: a person born outside Italy who holds another citizenship is treated as never having acquired Italian citizenship, unless one of five saving conditions applies. Beware the shorthand that it limits descent to a parent or grandparent born in Italy — that was the DECREE text. Conversion rewrote condition (c) into a test of whether an ascendant of the first or second degree holds, or held at death, exclusively Italian citizenship, and suppressed the “born in Italy” limb entirely; the amended text has been in force since 24 May 2025. The two tests diverge on the commonest case there is: an ancestor born in Italy who later naturalised abroad satisfies the old shorthand and fails the law in force. Claims already filed by 23:59 Rome time on 27 March 2025 are assessed under the prior rules.
Department of Foreign Affairs and TradeIrelandgovernment: The Irish government department (DFAT) that manages Foreign Births Register applications, passport services, and consular affairs. The DFAT processes all FBR applications submitted through fbr.dfa.ie.
Diário da RepúblicaPortugalgovernment: Portugal's official government gazette where laws are formally published. Lei Orgânica n.º 1/2026 was published in issue n.º 95/2026 on May 18, 2026.

E

Effective connectionPortugallegal: The English name for ligação efetiva, a requirement of Portugal's grandchild route (Article 1(1)(d)) — not of the parent route, and not of the great-grandchild naturalisation under Article 6(8). It is defined at Regulamento da Nacionalidade art. 10.º-A n.º 2 with three limbs: sufficient knowledge of Portuguese, no qualifying criminal conviction, and no national-security bar. An A2 certificate is the usual proof of the language limb, not a statutory presumption.
Egyszerűsített honosításHungarylegal: Hungary's simplified naturalization pathway for ethnic Hungarian diaspora under §4 of Act LV of 1993. Requires documented Hungarian ancestry, conversational Hungarian ability, and a clean criminal record. No government application fee.
EstrattoItalydocument: A certified extract of a civil-status record held by an Italian comune. DPR 396/2000 provides two forms: the estratto per riassunto (Art. 106), a summary of the entry and its annotations, and the estratto per copia integrale (Art. 107), an exact transcription of the register entry with every annotation and a certification that it matches the original. An estratto di nascita is a birth record; estratto di matrimonio a marriage record.

F

FBRIrelandgovernment: Foreign Births Register — the register maintained by Ireland's Department of Foreign Affairs and Trade for Irish citizens born abroad. Registration on the FBR is how people with Irish ancestry claim citizenship by descent.
FeststellungGermanylegal: The formal determination of whether a person does or does not hold German citizenship. It is made under §30 StAG, not §4 — §4 is the separate rule on acquisition by birth that a Feststellung usually turns on. §30(3) provides that a positive determination produces a Staatsangehörigkeitsausweis, and §38(2) Nr. 2 sets the fee at €51. For applicants living outside Germany the deciding Staatsangehörigkeitsbehörde is the Bundesverwaltungsamt in Cologne.
First-generation limitCanadalegal: The restriction introduced by Bill C-37 in 2009, preventing Canadian citizens born abroad from transmitting citizenship to their own children born abroad. Held unconstitutional in Bjorkquist v. Attorney General of Canada, 2023 ONSC 7152, which struck s. 3(3)(a) as contrary to ss. 6 and 15 of the Charter. Removed by Bill C-3 for births before December 15, 2025 — but not simply deleted: for births on or after that date it is replaced by the two-part test in the new s. 3(3). Section 3(5), the Crown-servant exception, applied throughout and still does.
FogadalomHungaryprocess: The Hungarian citizenship oath ceremony. After Budapest Főváros Kormányhivatala (the acting citizenship authority; the President of the Republic grants naturalisation) approves, applicants take the fogadalom at the venue they chose, after which they are officially Hungarian citizens and may apply for a Hungarian passport.
Foreign Birth RegistrationIrelandprocess: The process of registering on the FBR to claim Irish citizenship by descent. Application submitted online at fbr.dfa.ie, then printed, signed in front of a qualified witness, and mailed with original documents to the address printed on the form.
Free Territory of TriesteItalylegal: The Free Territory of Trieste was an international territory established by the Treaty of Paris 1947. Zone A (Trieste city and environs) was administered by Allied forces and came under Italian administration in 1954 — ancestors from Zone A are standard Friuli-Venezia Giulia cases. Zone B was administered by Yugoslavia and ceded to it by the Treaty of Osimo of 10 November 1975, made executive in Italy by Law 73 of 14 March 1977. Osimo Art. 3 allocated the citizenship of people who were Italian on 10 June 1940 and permanently resident there according to which state they were resident in when the treaty entered into force, so those still in Zone B were governed by Yugoslav law; Law 124/2006 covers them and their direct-line descendants.
Full AdoptionItalylegal: Adoption (adozione legittimante) that severs all legal ties to the biological family. The adopted child becomes the legal child of the adoptive parents. For Italian citizenship, full adoptions finalized in Italy on or after 7 July 1967 (Law 431/1967) or abroad on or after 1 June 1983 (Law 184/1983) transmit citizenship like biological parentage. Both dates are the laws' entry into force, not the dates printed in their titles.

G

Good Friday AgreementIrelandlegal: The 1998 peace agreement that, among other provisions, guarantees people born in Northern Ireland the right to identify as Irish, British, or both — and to hold Irish citizenship regardless of the 2005 birthright changes.
GrandfatheringItalylegal: The transitional limbs of Article 3-bis of Law 91/1992 that preserve old-rule eligibility. Three turn on filing: an application with its supporting documents filed at the competent consulate or comune by 23:59 Rome time on 27 March 2025; an application filed on the day of an appointment that the competent office had communicated to the applicant by that same deadline (a limb added when the decree was converted); or a judicial claim filed by that deadline. Anything later is governed by Article 3-bis — which is not a generation cap: its remaining conditions turn on an ascendant of the first or second degree holding, or having held at death, exclusively Italian citizenship, or on a parent having lived in Italy for two continuous years after acquiring citizenship and before the applicant was born.
GROIrelandgovernment: General Register Office — Ireland's civil registration authority in Roscommon, holding birth, marriage, and death records. To obtain certificates, contact the GRO directly. Note: irishgenealogy.ie is a free search and image service (records only accessible when over 100 years old for births, 75 for marriages, 50 for deaths) and does not issue certificates. Northern Ireland records are held separately at GRONI in Belfast.
GRONIIrelandgovernment: General Register Office for Northern Ireland — holds civil registration records (birth, marriage, death) for Northern Ireland, separate from the Republic's GRO. Located in Belfast. Order records at nidirect.gov.uk/articles/ordering-life-event-certificates.

H

HonosításHungarylegal: Hungarian for 'naturalization.' In the citizenship context, refers to the simplified naturalization (egyszerűsített honosítás) pathway for diaspora Hungarians claiming citizenship by descent.

I

IRCCCanadagovernment: Immigration, Refugees and Citizenship Canada — the federal department that processes citizenship applications.
IRNPortugalgovernment: Instituto dos Registos e do Notariado — the Portuguese government body (Ministry of Justice) that processes citizenship registration applications. All Portuguese citizenship by descent claims are ultimately processed by the IRN's Conservatória dos Registos Centrais (CRC) in Lisbon.

J

Jure SanguinisItalylegal: Latin for "by right of blood" — the principle that Italian citizenship descends through the bloodline rather than from place of birth. It is still the basis of Art. 1 of Law 91/1992, but since 24 May 2025 Art. 3-bis of that law treats a person born abroad who holds another citizenship as never having acquired Italian citizenship unless one of its listed exceptions applies.

K

KonzinfoHungaryprocess: The Hungarian Ministry of Foreign Affairs consular information portal (konzinfo.mfa.gov.hu) — an information site, not a booking system. Hungary maintains four career posts in the US (Washington DC, New York City, Los Angeles and Chicago) plus a Vice Consulate in Miami. Booking varies by post: New York takes citizenship appointments only by email. Application forms are pre-filled separately via Konzinfo Ügysegéd at konzinfougyseged.mfa.gov.hu.
KresyPolandlegal: The eastern borderlands of pre-WWII Poland (now Ukraine, Belarus, Lithuania), including cities like Lwów/Lviv, Wilno/Vilnius, and Grodno. The 1951 Act art. 4 excludes a defined class from citizenship on cumulative conditions (Polish citizenship on 31 Aug 1939, permanent residence abroad on 19 Jan 1951, and one of three limbs — treaty-based acquisition of another citizenship on the border change, Russian/Belarusian/Ukrainian/Lithuanian/Latvian/Estonian narodowość, or German narodowość, that last one NOT applying where the spouse was a Polish citizen living in Poland). The test does not turn on birthplace, though Kresy ancestry may affect which limb applies.

L

Landing recordCanadadocument: Historical immigration document recording an immigrant's arrival and admission to Canada. For arrivals before 1936, Library and Archives Canada (LAC) holds the records; for arrivals from 1936 on, Immigration, Refugees and Citizenship Canada (IRCC) holds them, and LAC has no copies.
Law 124/2006Italylegal: Law 124 of 8 March 2006 inserted Arts. 17-bis and 17-ter into Law 91/1992, creating a recognition route for people who had been Italian citizens resident in territory ceded to Yugoslavia — Istria, Fiume/Rijeka, Zara/Zadar and Dalmatia under the 1947 Treaty of Paris, and Trieste Zone B under the 1975 Treaty of Osimo (made executive in Italy by Law 73 of 14 March 1977). It is limited to the Yugoslav cessions and does not cover the Dodecanese, Libya or Italian East Africa. Art. 17-bis(1)(b) extends the right to 'persone di lingua e cultura italiane' who are their children or direct-line descendants, with no generational limit in the text, and Art. 17-ter(3)(c) requires documentation proving the applicant's own Italian language and culture.
Law 555/1912Italylegal: The 1912 Italian citizenship law that governed transmission and loss of citizenship from July 1, 1912 until August 15, 1992. Article 12 paragraph 2 was read as stripping minor children of Italian citizenship when their parent naturalized abroad — the reading the Sezioni Unite rejected in 2026, confining Article 12(2) to children who held only Italian citizenship and protecting dual-citizens-from-birth under Article 7.
Law 74/2025Italylegal: Law 74 of 23 May 2025, which converted Decree-Law 36/2025 (the Tajani Decree) with amendments; the amended text has been in force since 24 May 2025. Do not describe it as capping recognition at two generations — Article 3-bis counts no generations. It treats anyone born outside Italy who holds another citizenship as never having acquired Italian citizenship unless one of that article's saving conditions applies; the first- and second-degree language belongs to one of those ESCAPES, which is the opposite polarity. Italy's Constitutional Court left it standing in sentenza 63/2026, decided 11 March 2026 and deposited 30 April 2026: it held the challenges partly inadmissible and, on Articles 2 and 3 of the Constitution and on EU citizenship law, unfounded. The March date is the decision, the April date the written ruling.
Lei da NacionalidadePortugallegal: Portugal's primary citizenship statute — Law 37/81 of 3 October 1981 (Lei n.º 37/81 de 3 de outubro de 1981), as amended twelve times — most recently by Lei Orgânica n.º 1/2026. Governs who is Portuguese by birth, by descent, and by naturalization. The grandparent descent path was added by Lei Orgânica n.º 9/2015, not by Lei 43/2013 (which added the Sephardic naturalisation route in Article 6(7), since revoked).
Lei Orgânica n.º 1/2026Portugallegal: Portugal's 2026 nationality law reform (Lei Orgânica n.º 1/2026), in force 19 May 2026. For the grandchild route it added Article 1(3), which applies the Article 6(1)(c)–(h) requirements — Portuguese language and culture, history and national symbols, rights and the political organisation of the State, a solemn declaration, and three criminal, security and sanctions bars. It did NOT add the requirement that the grandparent be Portuguese 'originária'; that has been in the law since 2020. It made the registration that confers nationality constitutive (Article 19(2)), revoked the Sephardic naturalisation route in Article 6(7), let the Government naturalise some great-grandchildren with five years' legal residence in Portugal (Article 6(8), a discretionary naturalisation, not a descent route), and raised the general naturalisation residence requirement to 10 years (7 for CPLP and EU citizens). Applications pending on 19 May 2026 continue under the previous wording.
Lei Orgânica n.º 9/2015Portugallegal: The amendment that created Portugal's direct grandchild pathway, adding Article 1(1)(d) to the Lei da Nacionalidade on 29 July 2015. Its own title says so: “estendendo a nacionalidade portuguesa originária aos netos de portugueses nascidos no estrangeiro”. The route deliberately skips the middle generation — Article 1(1)(d) sets conditions about the grandparent and about you, and says nothing about your parent, so your parent need not have been Portuguese. Two conditions have since tightened: the grandparent must now have been Portuguese originária (by origin, not by naturalisation), and from 19 May 2026 Article 1 n.º 3 makes this route also require Article 6 n.º 1 alíneas c) to h) — language and culture, history and national symbols, rights and duties, a solemn declaration, and three criminal and security bars. It is no longer a documents-only path. Often misattributed to Lei 43/2013, which never amended Article 1.
Ligação efetivaPortugallegal: Portuguese for 'effective connection' — a requirement of the grandchild route (Article 1(1)(d) of the Lei da Nacionalidade). The Regulamento da Nacionalidade (DL 237-A/2006) defines it at art. 10.º-A n.º 2, and it has three limbs: sufficient knowledge of Portuguese, proved by one of the means listed in art. 25.º n.º 2; no qualifying criminal conviction; and no danger or threat to national security or defence. An A2 certificate is the usual proof of the language limb, not a statutory presumption — the CAPLE route in art. 25.º alínea c) names no CEFR level. Since 19 May 2026, Article 1(3) of the Lei also applies the Article 6(1)(c)–(h) requirements to this route, and the Regulamento has not yet been updated to say how those are proved.
Long-form birth certificateCanadadocument: Birth certificate that shows parentage (parents' names). Required for citizenship applications — short-form certificates that only show name and date of birth are not accepted.
Lost CanadiansCanadalegal: People who lost or never obtained Canadian citizenship because of outdated rules in earlier citizenship laws. IRCC says most cases were resolved by the 2009 and 2015 amendments, which restored or gave citizenship to about 20,000 people; Bill C-3 (December 15, 2025) reached those still excluded — notably the former s. 8 cohort, expressly excluded in 2009 by s. 3(1)(f)(iii) — and their descendants. Crediting the whole restoration to Bill C-3 conflates three separate reforms seventeen years apart.

M

Masovian VoivodePolandgovernment: The Mazowiecki Urząd Wojewódzki in Warsaw — the voivodeship office that handles citizenship confirmation (potwierdzenie) applications for most overseas Poles and descendants. Competence is assigned by Art. 55 of the 2009 Act according to the applicant's or ancestor's last place of residence in Poland, so a claim rooted in Kraków goes to the Małopolski Voivode; the Masovian Voivode is the default only 'w przypadku braku tej podstawy' — where no such basis exists, which covers most US applicants.
Metryka urodzeniaPolanddocument: Polish birth record (metrical book entry) — the primary source for documenting a qualifying Polish ancestor. Records are searchable for free at Szukajwarchiwach.gov.pl and obtainable from local Polish archives (archiwa państwowe). Note that the archive and the civil registry are different issuers with different fees: a state archive charges for certifying a copy, while an odpis from the civil registry (USC) is priced by the stamp-duty annex (Dz.U. 2025 poz. 1154) — and for a descent claim the usual row is not the standard 33 zł one but item 11, 39 zł, for a full copy issued after a pre-1946 register entry is transferred into the modern register.
Military ParadoxPolandlegal: The situation under Article 11 of the 1920 Act where a man still subject to Poland's active military service obligation could acquire a foreign citizenship only after first obtaining permission (zezwolenie) from the Minister of Military Affairs — and, failing that, "wobec Państwa Polskiego nie przestaną być uważane za obywateli polskich" (would not cease to be regarded as Polish citizens). Naturalizing in the United States may therefore not have broken his Polish citizenship. A 1932 amendment recast the requirement as a zwolnienie (release) from the universal military obligation. The statute sets no ages: conscription law ran from the year a man turned 21, with the reserve to 40 and pospolite ruszenie to the end of the year he turned 50.
Minor IssueItalylegal: Whether an Italian parent's naturalization abroad automatically cost their minor child Italian citizenship, breaking the bloodline for every descendant. Administrative practice read Article 12 of Law 555/1912 that way. The Cassazione Sezioni Unite resolved it in applicants' favor in sentenza n. 24045/2026, argued at the public hearing of April 14, 2026 and deposited July 26, 2026: under Article 7 a minor born abroad to an Italian parent in a country that grants citizenship by birth is a dual national from birth and keeps Italian citizenship even if that parent naturalizes, save a contrary treaty or a renunciation made after coming of age; Article 12 can reach only a minor who held Italian citizenship and no other. Interior Ministry Circular 65050 of August 10, 2026 told the prefectures to align civil-status practice, and supersedes the 2024 guidance only for naturalizations of cohabiting parents between July 1, 1912 and August 15, 1992.

N

NARAgovernment: National Archives and Records Administration. Holds historical immigration and passenger arrival records. Request records using Form NATF 81.
Naturalizationlegal: The legal process by which an immigrant becomes a citizen of their adopted country. For Italian citizenship by descent, whether your ancestor naturalized (and when) is critical to eligibility.
NIFPortugaldocument: Número de Identificação Fiscal — the Portuguese taxpayer identification number, needed for many dealings with Portuguese authorities, banks and property. It is not one of the three statutory limbs of ligação efetiva (Regulamento da Nacionalidade art. 10.º-A n.º 2), so do not rely on a NIF to establish a connection to Portugal for citizenship purposes.

O

OFFIHungarygovernment: Hungary's national translation and translation-certification office (Országos Fordító- és Fordításhitelesítő Iroda — National Translation and Translation Authentication Office). Who may certify a translation for a citizenship application, and for which documents, is set out on our Hungarian cost calculator page (thenextpassport.com/hungarian-citizenship/cost-calculator#who-may-certify-the-translation), under “Who May Certify the Translation — and What That Costs”.
OneletrajzHungaryprocess: Hungarian for 'curriculum vitae / autobiography.' Applicants must prepare a handwritten autobiographical statement on the prescribed application form in advance of the consulate appointment. The statement is written by hand (adults only; medical exemption available for those unable to write) and the consulate reviews it as part of the Hungarian-language conversation assessment.
Opłata skarbowaPolandlegal: Stamp duty of PLN 277 on the voivode's decision about possession or loss of Polish citizenship — item 27 of the annex to the ustawa o opłacie skarbowej (Dz.U. 2025 poz. 1154). It is owed from the moment you file, not when you win: art. 6 ust. 1 pkt 1 fixes the obligation «z chwilą dokonania zgłoszenia lub złożenia wniosku», so it is payable even if the decision goes against you. Separate from the €100 consular fee and paid to a different government — art. 12 ust. 1 makes the tax authority the wójt, burmistrz or prezydent miasta, and ust. 2 pkt 1 picks the one for the seat of the deciding organ, which for the Masovian Voivode is the City of Warsaw.
OptanteItalylegal: An optante (plural: optanti) is a person who exercised the right under Art. 19 of the 1947 Treaty of Paris to keep Italian citizenship rather than take the citizenship of the state receiving the ceded territory. The right belonged to people domiciled in that territory on 10 June 1940 who were over eighteen (or married) and whose customary language was Italian, and it had to be exercised within one year of the treaty entering into force. Art. 19(3) allowed the receiving state to require those who opted to move to Italy within a year of the option. Italy's own recognition law built on this right, Law 124/2006, reaches only the territories ceded to Yugoslavia; descendants otherwise follow standard jure sanguinis rules from the point of the option.

P

Petition for Naturalizationdocument: A formal application filed by an immigrant to become a U.S. citizen. Found in the C-File or at NARA. Lists personal details, arrival information, and the date citizenship was granted.
Polish Citizenship Act 1920Polandlegal: The first Polish citizenship law (Ustawa z dnia 20 stycznia 1920 r. o obywatelstwie Państwa Polskiego), in force from 31 January 1920. Under Article 11 pkt 1, acquiring a foreign citizenship caused loss of Polish citizenship. The one exception is in Article 11's second paragraph: a man subject to active military service needed the Minister of Military Affairs' permission first, and without it did not lose his Polish citizenship.
Polish Citizenship Act 1951Polandlegal: The 1951 Polish citizenship law (Ustawa z dnia 8 stycznia 1951 r. o obywatelstwie polskim) that fundamentally changed citizenship rules effective January 19, 1951. After that date, naturalization abroad alone does NOT cause loss of Polish citizenship — only a formal zezwolenie na zmianę obywatelstwa (permission to change citizenship, Article 11 ust. 1) does.
PotwierdzeniePolanddocument: Formal confirmation of Polish citizenship (Potwierdzenie Posiadania Obywatelstwa Polskiego), issued by the voivode for the person's place of residence — or last place of residence — in Poland under 2009 Act art. 55 ust. 1. Where no residence basis exists, the Masovian Voivode (Warsaw) decides. Required to prove Polish citizenship for overseas descendants unable to obtain a naturalization record.
Provincial vital statisticsCanadagovernment: Government offices in each Canadian province and territory that issue birth, marriage, and death certificates. Each has different fees and processing times.

R

RBACanadadocument: Registration of Birth Abroad — a historical certificate issued before February 15, 1977 for Canadian citizens born outside Canada. Precursor to the modern citizenship certificate.
Regulamento da NacionalidadePortugallegal: The Portuguese regulation implementing the Lei da Nacionalidade. It defines ligação efetiva at art. 10.º-A n.º 2 and lists the accepted proofs of Portuguese at art. 25.º n.º 2 — art. 25.º is the proof list, not the definition, and citing it as the definition is a common error. It is a Decreto-Lei (DL 237-A/2006), not a portaria — the earlier Portaria 1403-A/2006 was revoked by Portaria 176/2014 and should not be cited as live. An A2 certificate is the usual proof of the language limb, not a statutory presumption, and visits, a NIF or community membership are not part of the test.
Renunciation of citizenshipCanadalegal: Under the current Act, a deliberate application under Citizenship Act s. 9(1) to give up Canadian citizenship, approved by the Minister and evidenced by a certificate of renunciation. Section 9(1) opens: «Subject to subsection (2.1), a citizen may, on application, renounce his citizenship if he» meets its conditions, one of which, «does not reside in Canada», s. 9(2) lets the Minister «waive on compassionate grounds». It is a different thing from the automatic loss the older Acts imposed on people who acquired a foreign nationality without choosing to lose Canadian status — s. 3(1)(f) reversed that loss retroactively in 2009. How a renunciation affects a descent claim is set out, in the Act's words, in the Canadian parent guide.
Reporting JudgeItalyprocess: The relatore — the member of the panel who reports the case. Under Art. 379 of the Italian code of civil procedure the relatore opens the Cassazione hearing by summarizing the issues of the case, after which the public prosecutor gives its conclusions orally and counsel argue.
Responsible parentCanadalegal: The rule under the 1947 Act for births outside Canada between January 1, 1947 and February 14, 1977: citizenship passed through the father for a child born in wedlock, and through the mother only for a child born out of wedlock. Bjorkquist v. Attorney General of Canada, 2023 ONSC 7152 at [127] states it exactly that way, with no deceased-father exception — a limb this glossary carried until September 9, 2026 and could not source. IT NO LONGER DECIDES ELIGIBILITY. Paragraph 3(1)(g), added by Bill C-37 in 2009, makes such a person a citizen if either parent was a citizen at the time of the birth, and s. 3(7)(e) deems them a citizen from birth. Which parent it was still determines whose records IRCC will want.
Retention declarationCanadalegal: Two different rules, two different cohorts, restored seventeen years apart. Under the 1947 Citizenship Act the first generation born abroad had to declare to retain citizenship by age 22, extended to 24 with retroactive effect by An Act to Amend the Canadian Citizenship Act, S.C. 1952-53, c. 23 — a detail this site deleted as unsourceable on the morning of September 9, 2026 and restored the same day, once Bjorkquist v. Attorney General of Canada, 2023 ONSC 7152 was read at paragraph 134, reciting expert evidence that names the amending Act. Those conditions ceased when the 1977 Act replaced that statute on February 15, 1977 — not by any 2009 repeal — and anyone who had lost citizenship under them was restored on April 17, 2009 by Bill C-37, via s. 3(1)(f) and backdated to the moment of loss by s. 3(7)(d). The separate former Section 8 required people born abroad between February 15, 1977 and April 16, 1981 to apply to retain before turning 28. It was repealed on April 17, 2009, but its losers were EXPRESSLY EXCLUDED from the C-37 restoration by s. 3(1)(f)(iii), and were only restored on December 15, 2025 when Bill C-3 repealed that subparagraph.
RetroactivityItalylegal: Whether Article 3-bis of Law 91/1992 reaches people who were already Italian at birth under the older rules. By its own words it does — it treats such a person as never having acquired Italian citizenship, expressly including births before the article took effect — and the Constitutional Court found that constitutional in sentenza 63/2026 (decided March 11, 2026, deposited April 30, 2026). Claims already filed by 23:59 Rome time on March 27, 2025 fall outside it. What the Sezioni Unite decided on July 26, 2026 was a different question — the minor issue under Law 555/1912. Do not describe the reform as a two-generation cap: it counts no generations. Whether the restriction is compatible with EU citizenship law is still open: by ordinanza 147/2026, decided June 9, 2026 and deposited July 23, 2026, the Constitutional Court stayed its own proceedings and referred that question to the EU Court of Justice under Article 267 TFEU. Article 3-bis remains in force meanwhile.

S

Sentenza 142/2025Italylegal: Italian Constitutional Court judgment decided June 24, 2025 and deposited July 31, 2025, on referrals from the tribunals of Bologna, Rome, Milan and Florence attacking jure sanguinis without generational limits — Art. 1(1)(a) of Law 91/1992 and the pre-1992 provisions behind it. The Court struck nothing down: it declared most of the questions inadmissible and the surviving one, unreasonable disparity of treatment under Art. 3 of the Constitution, unfounded. It is not the source of the March 2025 grandfathering, which comes from the transitional limbs written into Art. 3-bis itself.
Sephardic citizenshipPortugallegal: Portugal's naturalisation route for descendants of Sephardic Jews, in Article 6(7) of the Lei da Nacionalidade — a naturalisation, not a descent route, added in 2013. Lei Orgânica n.º 1/2026 revoked it from 19 May 2026; applications already pending that day continue under the previous wording.
Sezioni UniteItalylegal: The 'Joint Sections' of Italy's Court of Cassation. Art. 67 of the ordinamento giudiziario fixes the panel at nine voting judges (an ordinary section sits five). Art. 374 of the code of civil procedure sends a case to them for questions of jurisdiction, for points of law the ordinary sections have decided differently, and for questions of particular importance; an ordinary section that will not follow a Sezioni Unite principle must refer the case back to them by reasoned order. Lower courts are not formally bound but in practice follow, and administrative offices such as consulates typically move once the relevant ministry updates its own guidance.
Simple AdoptionItalylegal: Adoption (adozione semplice) that retains the child's legal ties to their biological family while adding a new relationship with the adoptive parents. These cases are legally complex for citizenship purposes — consult an attorney.
StaatsangehörigkeitsausweisGermanydocument: The official certificate confirming German citizenship, issued under §30(3) StAG by the deciding Staatsangehörigkeitsbehörde — the BVA for applicants living abroad — after a successful Feststellung. It is not a precondition for a German passport: BVA says a mission will normally issue one on your existing German papers and the child's birth certificate, and asks for a Staatsangehörigkeitsausweis only where it doubts that you still hold German citizenship.
StAG §25Germanylegal: StAG §25 was in force from 1 January 1914 until 26 June 2024 — the RuStAG was signed 22 July 1913 but §41 set entry into force at 1 January 1914, and the 2024 reform repealed §25, which now reads § 25 (weggefallen). The repeal is prospective only: a loss that already happened under §25 is not undone. Its text in each era is quoted on the German dual-citizenship reform page. Since 27 June 2024 acquiring another nationality no longer costs you German citizenship; §17(1) now lists only three grounds of loss (§26 renunciation, §28 foreign armed forces, §35 withdrawal).
StAG §5 DeclarationGermanylegal: A statutory declaration under §5 StAG for people the old descent rules left out. §5(1) lists four groups: children of a German parent who did not acquire German citizenship at birth (Nr. 1 — typically children of German mothers under the pre-1975 rules, and children born out of wedlock to a German father before 1 July 1993, for whom §5(1) applies §4(1) sentence 2, so paternity must have been acknowledged or proceedings begun before the declarant's 23rd birthday); children of a mother who lost German citizenship by marrying a foreigner before the child's birth (Nr. 2); children who lost it through legitimation by a foreigner (Nr. 3); and the descendants of anyone in those three groups (Nr. 4). Everyone declaring must themselves have been born after the Basic Law took effect on 23 May 1949 — §5(1)'s opening words put that floor on all four groups, descendants included. Filing is free under §38(3) Nr. 4 and the deadline is 19 August 2031; what stops the clock is BVA receiving the declaration, not a decision on it.
StandesamtGermanygovernment: Germany's local civil registry office (comparable to a US county vital records office). Issues certified copies of birth, marriage, and death certificates (Geburtsurkunde, Eheurkunde, Sterbeurkunde). Fees are set per Land, so they vary: across five Land tariffs read at the cities' own fee pages the spread is roughly €12–€19.50 for a first certified copy and €6–€9 for each additional copy in the same order. A flat €12/€6 is one Land's tariff, not a national rate.
Substantial connection testCanadalegal: The second limb of Citizenship Act s. 3(3), for births outside Canada on or after December 15, 2025. It arises ONLY where the citizen parent was themselves born outside Canada and holds citizenship by descent — a parent born in Canada, or one who was granted citizenship (naturalized), never faces it. Where it does apply, the exclusion bites only if "neither of the person's parents who was a citizen was physically present in Canada for at least 1,095 days before the person's birth", so one qualifying parent defeats it. IRCC describes the days as cumulative and countable at any time before the birth, and publishes form CIT 0555 for working out the total. Section 3(5) sets the whole subsection aside for the child or grandchild of a person serving abroad with the Canadian Armed Forces, the federal public administration or the public service of a province. A parallel rule in s. 5.1(4) covers adoptions.

T

Tłumacz przysięgłyPolandprocess: A statutory office held by named individuals on a register published by the Polish Ministry of Justice, under the ustawa o zawodzie tłumacza przysięgłego of 25 November 2004. The statutory rate (44.07 zł per 1,125-character page for English-to-Polish translation, per Dz.U. 2025 poz. 312 § 2) binds only work ordered by a court, prosecutor, police or public-administration body; private commissions are priced by contract.
Treaty of Paris 1947Italylegal: The Treaty of Peace with Italy, signed in Paris on 10 February 1947 and given effect in Italian law by Legislative Decree 1430/1947 (ratified by Law 3054/1952). Its territorial provisions ceded Istria, Fiume/Rijeka, Zara/Zadar and most of Dalmatia to Yugoslavia and the Dodecanese to Greece, and renounced Italian sovereignty over Libya and Italian East Africa. Art. 19 gave people domiciled in ceded territory on 10 June 1940 who were over eighteen (or married) and whose customary language was Italian the right to opt for Italian citizenship, within one year of the treaty entering into force.
TrianonHungarylegal: The Treaty of Trianon, signed in 1920 and in force on 26 July 1921, which transferred large portions of historic Hungary to neighboring states. Article 61 of the Act enacting it removed Hungarian citizenship on that date from everyone whose commune of pertinence (illetőség) lay in a detached territory — not everyone born there, and not everyone living there. Because §4(3) asks whether an ascendant «magyar állampolgár volt» — WAS a Hungarian citizen — that loss is part of the claim rather than an obstacle to it.

U

Ufficio di Stato CivileItalygovernment: The civil registry office within an Italian comune. Responsible for recording births, marriages, deaths, and citizenship status. This is where you request Italian vital records.
USCISgovernment: U.S. Citizenship and Immigration Services. Runs the Genealogy Program. The index search (Form G-1041) is $30 filed online or $80 on paper as of the 05/29/26 fee edition — the $65 figure was the pre-2024 rate.

V

Vital Recorddocument: An official government record of a life event — birth, marriage, death, or divorce. You will need certified copies (not photocopies) from the issuing jurisdiction.

Z

Zezwolenie na zmianę obywatelstwaPolandlegal: Permission to change citizenship (zezwolenie na zmianę obywatelstwa) — the statutory term of art for formal release from Polish citizenship under the 1951 and 1962 Acts. A signed decree issued by Polish authorities. Voluntary foreign naturalization alone does not cause citizenship loss without this permit. Note: zwolnienie in the 1920-Act military context means release from military-service obligation, a different concept.
