How to Apply for Portuguese Citizenship by Descent

Three ways to file — one queue

Nationality registration is the exclusive competence of the Conservatória dos Registos Centrais; a consular post intervenes only as an intermediary registry. gov.pt lists three channels. None of them is faster than the others, because none of them is the thing deciding your case. Not every post takes every route:Portugal's official guidance lists your local consulate among the places to apply for the grandchild route (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 — 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.

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.

Step-by-step application process

1. 1

   Gather vital records

   Collect the birth, marriage and death certificates your route needs, from your Portuguese ancestor down to yourself. For US-issued documents you will need certified copies (not photocopies) with apostilles from the Secretary of State of the issuing state, and a translation only if the conservador asks — documents in English are exempt by default (Regulamento art. 37.º n.º 2).

2. 2

   Identify the Portuguese birth record that proves nationality (assento de nascimento)

   The parent route is instructed with proof of one parent's Portuguese nationality (Regulamento art. 8.º n.º 2). The grandchild route needs the birth records of the grandparent who was Portuguese by origin and of the parent who descends from them (art. 10.º-A n.º 3 al. b)). You need not order Portuguese civil-registry certificates yourself if you give details that identify the record — the registry obtains them (art. 37.º n.º 4); certificates should, where possible, be full copies (art. 37.º n.º 3). If your grandparent (or parent) was born outside Portugal, the record that proves Portuguese nationality is the Portuguese birth record made by inscription at the Conservatória dos Registos Centrais, or the registered declaration (Article 21(4)). If no such record exists, get advice before filing.

3. 3

   Prove Portuguese — usually by the CIPLE A2 (grandparent path only)

   The accepted proofs of Portuguese include: 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). For most US applicants that means the CIPLE, set by CAPLE — Centro de Avaliação e Certificação de Português Língua Estrangeira, Faculdade de Letras da Universidade de Lisboa — register at https://caple.letras.ulisboa.pt/inscricao, not with the Camões Institute, which does not run this exam. 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. Each centre decides how many places it opens and only the free ones are shown at sign-up; CAPLE publishes no figure for how quickly they fill. Registration closes 21 days before a session's first exam date. 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).

4. 4

   Check the effective connection limbs (grandparent path only)

   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. The CIPLE A2 is the usual proof of the language limb; the other two limbs are no qualifying criminal conviction and no national-security threat. The definition names no other evidence.

5. 5

   Grandparent path, filed from May 19, 2026: the Article 1(3) requirements

   Article 1(3) of Lei 37/81, inserted by Lei Orgânica n.º 1/2026, applies Article 6(1)(c)–(h) to the grandchild route: (c) knowledge of the Portuguese language AND of Portuguese culture, history and national symbols; (d) knowledge of fundamental rights and duties and of the political organisation of the State; (e) a solemn declaration of adherence to the principles of the democratic rule of law; (f) no final conviction with an effective prison sentence of more than 3 years for terrorism, violent or organised crime, crimes against State security or aiding illegal immigration; (g) no danger to national security or defence; (h) not being subject to UN or EU restrictive measures. How these requirements will be tested is not yet published — the Regulamento da Nacionalidade has not been updated. 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'.

6. 6

   Grandchild path only: order your criminal record certificates

   Skip this step entirely if you are claiming through a Portuguese parent. The criminal-record requirement sits in art. 10.º-A n.º 3 al. c) of the Regulamento da Nacionalidade, which governs netos. The parent route is art. 8.º, whose n.º 2 states its entire documentary instruction — proof of one parent's Portuguese nationality — and asks for no criminal record; Article 1(3) of Lei 37/81, inserted by Lei Orgânica n.º 1/2026, attaches the art. 6.º n.º 1 al. c)–h) requirements to alínea d) only. The IRN forms match: Modelo 1D has a criminal-record section, Modelo 1C has none. On the grandchild path you need certificates «emitidos pelos serviços competentes portugueses, do país da naturalidade e da nacionalidade, bem como dos países onde tenha tido e tenha residência» (art. 10.º-A n.º 3 al. c)) — that is, from your country of birth, your country of nationality and every country where you have lived or live: countries, not US states. You do not order the Portuguese certificate yourself — art. 37.º n.º 7 al. a) has the registry obtain it. And the certificate from your country of birth or nationality is dispensed if, after reaching the age of criminal responsibility, you lived in another country (art. 37.º n.º 8). For a US applicant, the US certificate is the FBI Identity History Summary (fbi.gov/investigate/identify-me).

7. 7

   Choose how you file — it does not change your queue position

   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. gov.pt lists three channels: by post, online, or in person. The online channel is reserved to mandatários (lawyers and solicitors) because it is mandatory for them, not because it is faster. However a file is lodged, it reaches the same Central Registry, which analyses files by entry date within each legal ground. Choose on what your route allows and on how confident you are that the file is complete.

8. 8

   Wait for CRC Lisbon review

   However you filed, the Conservatória dos Registos Centrais (CRC) in Lisbon reviews and decides all citizenship-by-descent applications — that competence is exclusive to it. Expect to wait: files are worked in order of entry, and urgency is granted only on exceptional grounds the applicant proves. CRC may issue an exigência requesting additional documents. Respond promptly.

9. 9

   Receive decision and register citizenship

   If approved, your birth is registered in the Portuguese civil registry (assento de nascimento). Since Lei Orgânica n.º 1/2026, that registration has constitutive effect (Article 19(2) of Lei 37/81: it «tem efeitos constitutivos»). You can then apply for a Portuguese passport at any Portuguese consulate or in Portugal. Adult passport fees vary — confirm current rates at the consulate.

Document checklist

US-issued documents need an apostille, and a translation only if the conservador asks — documents in English are exempt by default (Regulamento art. 37.º n.º 2). You need not order Portuguese civil-registry certificates yourself if you give details that identify the record (art. 37.º n.º 4).

Name discrepancy warning

US Portuguese consulates — and what some will not take

Portugal has no single nationwide jurisdiction map the way Italy does, but that is not the same as “file anywhere.” 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 labels it “realizado exclusivamente pela Conservatória dos Registos Centrais em Lisboa,” and New Bedford tells applicants to send it straight to the CRC in Portugal — so check your post's own page before booking. Posts also set other intake rules: Newark accepts a parent-route application only from someone born in the USA who currently resides in New Jersey, Pennsylvania, or Delaware.
