Portuguese Citizenship by Descent

Research hub for Portuguese citizenship by descent. Some children and grandchildren of Portuguese nationals may qualify, through the Instituto dos Registos e do Notariado (IRN), Ministry of Justice, Portugal.

Last verified: September 5, 2026 · Maintained by The Next Passport (Warner Creates LLC).

You may qualify for Portuguese citizenship by descent if a parent or grandparent was a Portuguese citizen. On the parent route, a child born abroad becomes Portuguese by origin once the birth is inscribed in the Portuguese civil registry or they declare that they want to be Portuguese — no language exam. The grandparent route requires a grandparent who was Portuguese by origin and did not lose that nationality, a declaration, an effective connection, and — since May 19, 2026 — language, culture and civics requirements plus criminal, security and sanctions bars. The government fee is €175–€220 — IRN €175 direct; €220 (~$257) at a US consulate; minors free. Portugal allows dual citizenship. Portugal's official guidance lists your local consulate among the places to apply, as well as the Conservatória dos Registos Centrais, a Balcão da Nacionalidade and civil registry offices — but of the 6US consulates, at least Newark, New Bedford and San Francisco direct grandchild applications straight to the Conservatória dos Registos Centrais instead of accepting them, so check your post's own page before booking.

If you were born before 3 October 1981, different rules applied at your birth. Under the 1959 law a child born abroad was Portuguese through the father after a declaration, a registration of the birth in the Portuguese civil registry, or domicile in Portugal (Base IV); through the mother only where the father was stateless or unknown (Base V); and with no declaration at all where a parent was abroad in the service of the Portuguese State (Base II).

Portuguese Nationality Law Updated (in force May 19, 2026)

Lei Orgânica n.º 1/2026 (in force May 19, 2026) is the most significant reform to Portugal's nationality law in over a decade. Key changes: (1) naturalization residency requirement raised to 10 years (7 years for CPLP nationals and EU citizens); (2) the Sephardic Jewish naturalisation route in Article 6(7) was revoked outright; (3) a new Article 6(8) lets the Government naturalise a third-degree descendant of a Portuguese originário who has five years' legal residence in Portugal — a residency waiver, not a new descent route. For descent, two changes matter. On the parent route under Article 1(1)(c), a new Article 19(2) makes the registration that confers nationality constitutive. On the grandparent route under Article 1(1)(d), a new Article 1(3) applies the Article 6(1)(c)–(h) requirements. The requirement that the grandparent be Portuguese originária is not new — it has been in the law since Lei Orgânica n.º 2/2020. Article 7(2), Lei Orgânica n.º 1/2026 — procedures pending on 19 May 2026 continue under the previous wording, which spares them the new Article 1(3) requirements but already required a grandparent of Portuguese nationality 'originária'.

Who may qualify for Portuguese citizenship by descent

Descent is governed by the Lei n.º 37/81 de 3 de outubro de 1981 (Lei da Nacionalidade), as amended twelve times — most recently by Lei Orgânica n.º 1/2026, de 18 de maio. Nationality by origin does not pass to a descendant born abroad on its own: each route has conditions, and they differ substantially by generation. On either route, an adult applicant must show that their legal relationship with the parent they claim through (on the grandchild route, with their own parent) was established while they were under 18, or came from a court judgment with the application made within three years of it becoming final (Lei n.º 37/81, art. 14.º).

Children of a Portuguese parent

If you were born abroad to a Portuguese mother or father, you become Portuguese by origin once your birth is inscribed in the Portuguese civil registry or you declare that you want to be Portuguese (Article 1(1)(c)). That registration is what confers it (Article 19(2)), and it counts from your birth (Article 11). No language test applies, and there is no effective connection test. The route covers one generation: each person registers or declares for themselves. It can be filed at a consular post, by post or online, but intake rules vary by post — see where to apply, below.

Grandchildren of a Portuguese citizen

Grandchildren may claim directly under Article 1(1)(d), without your parent needing to hold Portuguese citizenship, if a grandparent was Portuguese by origin and did not lose that nationality, you declare that you want to be Portuguese, and you have ligação efetiva (effective connection) to the Portuguese community. The Article 1(1)(d) grandchild route has required a grandparent of Portuguese nationality 'originária' — Portuguese by origin — since Lei Orgânica n.º 2/2020; the 2026 reform did not add that word, so a grandparent who became Portuguese by naturalisation has not opened this route since that law. What Lei Orgânica n.º 1/2026 did add is Article 1(3), which applies the Article 6(1)(c)-(h) requirements to this route: knowledge of the Portuguese language AND of Portuguese culture, history and national symbols; knowledge of fundamental rights and the political organisation of the State; a solemn declaration of adherence to the principles of the democratic rule of law; and three bars covering criminal convictions, national security, and UN or EU restrictive measures. Article 7(2) keeps applications pending on 19 May 2026 under the previous wording, which spares them Article 1(3) but not 'originária'. Article 4 required the Regulamento da Nacionalidade to be revised by 16 August 2026 to say how the new requirements are proved; that deadline passed unmet, and the Regulamento was still on its 2023 text (DL 41/2023) as of 6 September 2026.

Great-grandchildren and beyond

Lei 37/81 has no descent route that reaches you directly from a great-grandparent. Lei Orgânica n.º 1/2026 added Article 6(8): discretionary naturalisation for great-grandchildren with five years' legal residence in Portugal — not a descent route. Whether anyone in between has a route of their own depends on when and where they were born. Consult a licensed Portuguese attorney.

The Language Requirement and the A2 Exam (grandchild path only)

Grandchildren must show sufficient knowledge of Portuguese. The usual proof is the CIPLE A2 exam — the Certificate of Initial Portuguese Language Proficiency. The exam is set, marked and certified by CAPLE — Centro de Avaliação e Certificação de Português Língua Estrangeira, Faculdade de Letras da Universidade de Lisboa, and is sat at CAPLE-authorised exam centres (LAPE) in Portugal and abroad. Since May 19, 2026, Article 1(3) also requires knowledge of Portuguese culture, history and national symbols, so a language certificate alone no longer covers the requirement. For people with a serious illness or a disability, and for people aged 60 or over who cannot read or write, the proof of Portuguese must be adapted to their capacity (Regulamento art. 25.º n.º 6).

  • Fee: €95
  • Sessions per year: CAPLE runs three worldwide sessions a year (May, July, November), but each US centre offers only some: in 2026 Washington DC had all three, Boston and Berkeley May and November, Newark May only
  • US locations: Berkeley (UC Berkeley), Boston, Newark, and Washington DC
  • Registration:open year-round and closing 21 days before a session's first exam date. Each centre decides how many places it opens, and only the ones still free appear when you register — so book early, but note that CAPLE publishes no figure for how quickly places fill
  • Accepted language proofs: CIPLE A2, or a certificate from a recognised school showing at least two school years of Portuguese as a curricular subject (Regulamento art. 25.º n.º 2)

Camões — Instituto da Cooperação e da Língua, I.P. is the Foreign Ministry's institute for teaching and promoting Portuguese abroad, and its name is on a lot of Portuguese course material, but it does not set, run or issue the CIPLE. Its roles here are adjacent: the Portuguese state's recognition of CAPLE certification runs through it, and under Regulamento da Nacionalidade art. 25.º n.º 2 al. b) it accredits the venues for a separate public-network language test taken abroad. Its own certificates (Certificação EPE, Camões Júnior) are school-network exams, not the CIPLE.

Dual citizenship & the pre-1981 loss rules

Portugal has allowed dual citizenship since October 3, 1981 (Law 37/81, Article 8) — acquiring a foreign nationality after that date is not a ground for losing Portuguese nationality. Subject to what other law provides, the only ground of loss in the Act is a declaration, by someone who also holds another nationality, that they do not want to be Portuguese (Article 8). So a grandparent who was Portuguese by origin and became a US citizen after that date did not lose Portuguese nationality by doing so. That settles loss, not whether they were Portuguese in the first place.

Before 3 October 1981, Lei n.º 2098 (1959) applied. Under it, a Portuguese national lost that nationality by voluntarily acquiring a foreign nationality, and a Portuguese woman lost it by marrying a foreigner (unless she did not acquire her husband's nationality, or declared before the marriage that she would keep hers). Lei 37/81 reverses both. A person who lost Portuguese nationality under Lei 2098 by marrying a foreigner (Article 30) or by voluntarily acquiring a foreign nationality (Article 31) reacquires it — by default where no definitive registration of the loss (registo definitivo da perda) was ever drawn up, or by declaration where one was. Reacquisition is retroactive, to the date of the marriage (Article 30(3)) or of the foreign naturalisation (Article 31(3)), and the State's grounds for opposition (Articles 9 and 10) do not apply. A Portuguese civil registry check shows whether a loss was registered. Lei 2098 had other grounds of loss too, so get advice if another may apply.

Documents you'll need

  • Birth certificates for every link in the chain — apostilled if US-issued; a translation only if the conservador asks — documents in English are exempt by default (Regulamento art. 37.º n.º 2)
  • Marriage certificates — apostilled if US-issued; a translation only if the conservador asks (Regulamento art. 37.º n.º 2)
  • Death certificates for deceased ancestors — apostilled if US-issued; a translation only if the conservador asks (Regulamento art. 37.º n.º 2)
  • The Portuguese ancestor's Portuguese birth record — if they were born abroad, the birth record made by inscription in the Portuguese civil registry, or the registered declaration (Article 21(4)). You need not obtain Portuguese civil-registry certificates yourself if you give details that identify the record — place and date of birth or marriage, and the conservatória and record number if known — because the registry obtains them (Regulamento art. 37.º n.º 4)
  • Language proof (grandchild path only) — usually the A2 certificate issued by CAPLE (Universidade de Lisboa) after passing the CIPLE A2 exam
  • Proof of effective connection (grandchild path only) — the language proof above covers the language limb; the other two limbs are no qualifying criminal conviction and no national-security bar (Regulamento art. 10.º-A n.º 2)
  • Criminal record certificates (grandchild path only) — from your country of birth, your country or countries of nationality, and the countries where you live or have lived — countries, not US states (Regulamento art. 10.º-A n.º 3 al. c)). ORDER LAST — expires 3 months from issuance. The parent path does not require one: art. 10.º-A n.º 3 al. c) imposes it on netos, while the parent route (art. 8.º n.º 2) asks only for proof of the parent's Portuguese nationality

Where to apply

IRN (Instituto dos Registos e do Notariado)

IRN is the Portuguese government body that adjudicates all citizenship-by-descent applications, through the Conservatória dos Registos Centrais (CRC) in Lisbon. Registration of nationality is the CRC's exclusive competence: a consular post intervenes only as an intermediary registry and forwards your file to Lisbon. gov.pt lists three ways to file — by post to a Balcão da Nacionalidade, online, or in person — and the online channel is restricted to mandatários (lawyers and solicitors) because it has been mandatory for them since 1 December 2023, not because it is faster. A posted declaration must be signed before someone with power to recognise the signature, and one missing a required formality or supporting document can be rejected on intake within 30 days (Regulamento art. 32.º n.º 3). Whichever way you file, your case lands in the same queue.

US Portuguese consulates — and what some will not take

There are 6 Portuguese consular posts in the United States: Boston, New Bedford, Newark, New York, Providence, and San Francisco. The Embassy in Washington, D.C. has a consular section as well; there is no Portuguese consulate in Los Angeles. Portugal's official guidance lists your local consulate among the places to apply for the grandchild route (Art. 1(1)(d)), alongside the Conservatória dos Registos Centrais, a Balcão da Nacionalidade and civil registry offices — but at least three US posts, Newark, New Bedford and San Francisco, direct grandchild applications straight to the Conservatória dos Registos Centrais instead, so check your post's own page first. If you post an application, sign the declaration in front of someone with power to recognise signatures: a declaration missing a required formality is rejected on intake. The parent route (Art. 1(1)(c)) may be filed at a consular post, by post to a Balcão da Nacionalidade, or online through a mandatário, and individual posts impose intake rules: Newark accepts parent-route applications only from applicants born in the USA who currently reside in NJ, PA or DE.Check the post's own page before booking.

Application guides

Detailed guides for each Portuguese citizenship by descent path.

Through Your Parent

Portuguese citizenship through a Portuguese parent under Article 1(1)(c) of Lei 37/81: nationality by origin once your birth is inscribed in the Portuguese civil registry or you declare that you want to be Portuguese. No language exam, no effective connection requirement — the simplest descent path.

Through Your Grandparent

Claim Portuguese citizenship under Article 1(1)(d) of Lei 37/81 through a grandparent who was Portuguese by origin and did not lose that nationality. Requires a declaration, ligação efetiva (effective connection) and, since May 19, 2026, the Article 6(1)(c)–(h) requirements: Portuguese language and culture, history and national symbols; fundamental rights and the political organisation of the State; a solemn declaration of adherence to democratic principles; and bars covering criminal convictions, national security, and UN or EU restrictive measures.

Frequently asked questions

How long does Portuguese citizenship by descent take?

Portugal publishes no processing time for citizenship by descent, so we no longer publish one either. The Conservatória dos Registos Centrais has exclusive competence over nationality registration and analyses files by entry date within each legal ground, so how you file does not change your position in the queue. A consular post acts only as an intermediary registry, so there is no consulate queue to bypass and no faster lane to buy. Confirm your own position with IRN using your process number.

Do I need to speak Portuguese to claim citizenship?

Only if you are claiming through a grandparent. The grandchild route requires sufficient knowledge of Portuguese, usually proved with the CIPLE A2 certificate, and since May 19, 2026 it also requires knowledge of Portuguese culture, history and national symbols. The CIPLE exam board is CAPLE — Centro de Avaliação e Certificação de Português Língua Estrangeira, Faculdade de Letras da Universidade de Lisboa — not the Camões Institute, which teaches and promotes Portuguese abroad but does not set or issue the CIPLE. The parent route has no language requirement: if you were born abroad to a Portuguese mother or father, you become Portuguese by origin once your birth is inscribed in the Portuguese civil registry or you declare that you want to be Portuguese (Article 1(1)(c)). That registration is what confers it (Article 19(2)), and it counts from your birth (Article 11). No language test applies.

Can I keep my US citizenship if I become Portuguese?

Yes. Portugal fully allows dual citizenship; no renunciation required (Law 37/81, Art. 8). Portugal's rule since October 3, 1981 (Law 37/81, Article 8) — acquiring a foreign nationality after that date is not a ground for losing Portuguese nationality. You are not required to renounce US citizenship at any point in the process.

Can I claim through my great-grandparent?

Not by descent. Lei 37/81 has no route that reaches you directly from a great-grandparent. Lei Orgânica n.º 1/2026 added Article 6(8): discretionary naturalisation for great-grandchildren with five years' legal residence in Portugal — not a descent route. Whether anyone in between has a route of their own depends on when and where they were born, so consult a licensed Portuguese attorney about your family's specific history.

What is ligação efetiva (effective connection)?

Effective connection to the Portuguese community is a requirement of the grandchild route under Article 1(1)(d) of Lei 37/81. It is defined in the Regulamento da Nacionalidade (DL 237-A/2006), art. 10.º-A n.º 2 — effective connection (ligação efetiva) is sufficient knowledge of Portuguese proved under art. 25.º n.º 2, plus no qualifying criminal conviction and no national-security bar. An A2 certificate is the usual proof of the language limb. Holding a NIF, visiting Portugal, owning property there or belonging to a Portuguese cultural association are not limbs of that test. Since May 19, 2026, Article 1(3) also applies further requirements to the grandchild route — language and culture, civics, a declaration of adherence to democratic principles, and criminal, security and sanctions bars.

Can I apply at any Portuguese consulate in the US?

Not always. There are 6 Portuguese consular posts in the US — Boston, New Bedford, Newark, New York, Providence, and San Francisco — plus a consular section at the Embassy in Washington, D.C. There is no Portuguese consulate in Los Angeles. Portugal's official guidance lists your local consulate among the places to apply for the grandchild route under Article 1(1)(d), as well as the Conservatória dos Registos Centrais, a Balcão da Nacionalidade and civil registry offices. But at least three US posts direct grandchild applications straight to the Conservatória dos Registos Centrais instead of accepting them: Newark's own page calls it 'realizado exclusivamente pela Conservatória dos Registos Centrais em Lisboa', and New Bedford says it must be sent directly to the Conservatória dos Registos Centrais in Portugal and not to the consulate. Check your post's own page before booking. For the parent route, individual posts also set intake rules: Newark accepts it only from applicants born in the USA who currently reside in NJ, PA, or DE. You are not obliged to use a consulate at all: gov.pt lists post and online alongside in-person filing, and a private applicant may post the file directly to a Balcão da Nacionalidade. A posted declaration must be signed before someone with power to recognise the signature, and one missing a required formality or supporting document can be rejected on intake within 30 days (Regulamento art. 32.º n.º 3). None of these choices changes your position in the queue, because the Conservatória dos Registos Centrais decides every file.
