Descent Path · First GenerationPortuguese Citizenship by Descent Through a Parent
This page is informational, not legal advice. It describes Portuguese citizenship law in general terms based on publicly available legislation and Portuguese government sources. For guidance on your specific situation, consult a licensed Portuguese immigration attorney. Information reflects Portuguese law as of September 5, 2026, including Lei Orgânica n.º 1/2026 (in force May 19, 2026), which made the registration that confers nationality constitutive (Article 19(2)) and added new requirements to the grandchild route only.

If you were born abroad to a Portuguese mother or father, you may qualify for Portuguese citizenship by descent. 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). The fee is €175 direct to the IRN, or €220 (~$257) filed at a US consulate, with no language exam and no residence requirement on the parent path. Portugal allows dual citizenship, so you keep your US citizenship. Portugal publishes no processing time: every file is decided by the Conservatória dos Registos Centrais in Lisbon, in order of entry.
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). Get advice before relying on this page.
| Who qualifies | Born abroad to a parent who was Portuguese when you were born — Portuguese by origin once your birth is inscribed in the Portuguese civil registry or you declare that you want to be Portuguese. If you are an adult, your legal relationship with that parent must have been established while you were under 18 (Article 14) |
| Government fee | €175 direct to the IRN, or €220 (~$257) filed at a US consulate (parent route). Minors are free. |
| Processing time | Not published. One CRC Lisbon queue for every submission route, worked in order of entry |
| Language exam | None on the parent path (A2 applies only to the grandparent route) |
| Dual citizenship | Portugal fully allows dual citizenship; no renunciation required (Law 37/81, Art. 8) — you keep your US citizenship |
| Legal basis | Lei da Nacionalidade (Law 37/81), Article 1(1)(c) — Portuguese by origin, on registration or declaration |
Simplest descent path available
- No language exam. The A2 Portuguese exam (CIPLE) is required only for the grandparent path — not for children of a Portuguese citizen.
- No effective connection requirement. The ligação efetiva standard applies only to grandchildren under Article 1(1)(d) — not to direct children.
- Registration is what confers it. 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. That registration is constitutive (Article 19(2)), and it counts from your birth (Article 11).
Legal basis: Article 1(1)(c) of Lei 37/81
Portuguese citizenship by descent for children of a Portuguese parent born abroad is governed by Article 1(1)(c) of 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. 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. That registration is what confers it (Article 19(2)), and it counts from your birth (Article 11).
So Article 1(1)(c) sets two conditions. Your parent must have been Portuguese when you were born, and your birth must be inscribed in the Portuguese civil registry or you must declare that you want to be Portuguese. The statute does not require the Portuguese parent to have held a passport, had a NIF, or kept any active connection to Portugal, and for births from 3 October 1981 it treats a Portuguese mother and a Portuguese father alike. Your nationality is then proved by your birth record made by inscription in the Portuguese civil registry, or by the registered declaration (Article 21(4)).
If you are an adult: your parentage must date from your minority (Article 14)
An adult applicant must show that their legal relationship with the Portuguese parent they claim through was established while they were under 18 — for example by being named on the birth record at birth, or recognised before turning 18 (Lei n.º 37/81, art. 14.º n.º 1; gov.pt, ‘Pedir a atribuição de nacionalidade portuguesa para cidadão residente no estrangeiro’, updated 27 March 2026). A relationship established in adulthood counts only where it came from a court judgment, and the application must then be made within three years of that judgment becoming final (art. 14.º n.os 2–3, added by Lei Orgânica n.º 1/2024, in force 1 April 2024). For a judgment that became final before 1 April 2024, the three years run from that date (Lei Orgânica n.º 1/2024, art. 5.º).

This distinguishes the parent path from the grandchild route, which came later: Lei Orgânica n.º 9/2015, de 29 de julho — added Article 1(1)(d), the grandchild route by origin (Lei 43/2013 added the Sephardic naturalisation route in Art. 6(7), not this one). That route requires a grandparent who was Portuguese by origin and did not lose that nationality, a declaration, and ligação efetiva (effective connection) — which the Regulamento defines as sufficient Portuguese, no qualifying criminal conviction and no national-security bar. Since May 19, 2026 Article 1(3) has added the Article 6(1)(c)–(h) requirements to it. None of those requirements applies to the parent route.
Article 1(1)(c): what the statute says
«Os filhos de mãe portuguesa ou de pai português nascidos no estrangeiro se tiverem o seu nascimento inscrito no registo civil português ou se declararem que querem ser portugueses» — children of a Portuguese mother or a Portuguese father born abroad, if their birth is inscribed in the Portuguese civil registry or if they declare that they want to be Portuguese. Lei n.º 37/81, Article 1(1)(c) (our translation). No language requirement. No effective connection requirement. No residency requirement.
Parent path vs. grandparent path: what's the difference?
| Requirement | Through Parent (Art. 1(1)(c)) | Through Grandparent (Art. 1(1)(d)) |
|---|---|---|
| The Portuguese ancestor | Parent was Portuguese when you were born | Grandparent of Portuguese nationality originária (by origin), never lost |
| What you do | Birth inscribed in the Portuguese civil registry, or a declaration | Declaration |
| Portuguese language | Not required | Required — usually proved with the CIPLE A2 exam |
| Effective connection (ligação efetiva) | Not required | Required — sufficient Portuguese, no qualifying conviction, no national-security bar |
| Article 1(3): culture, history and national symbols; fundamental rights and the political organisation of the State; solemn declaration of adherence to democratic principles | Not required | Required since May 19, 2026 (applications pending on that date excepted) |
| Article 1(3) bars: criminal convictions, national security, UN or EU restrictive measures | Not applied | Apply since May 19, 2026 |
| Residency in Portugal | Not required | Not required |
| Government fee (adults; minors free) | €175 direct to the IRN, or €220 (~$257) filed at a US consulate | ~€175 registry emolument |
| Published processing time | None | None |
| Who decides, and how you file | CRC Lisbon — same queue by post, online or in person | CRC Lisbon — same queue by post, online or in person |
We do not publish a processing range for either path. Portugal does not publish one, and the figures we used to show here were our own. See processing times for what actually drives the wait.
The critical question: was your parent Portuguese when you were born?
Article 1(1)(c) looks to the parent's status at the moment of your birth: the parent must have been Portuguese then. If the parent had lost Portuguese nationality before you were born, the question becomes whether that loss still stands — and for two pre-1981 grounds of loss, Lei 37/81 reverses it retroactively.
That makes the date of a parent's US naturalization important:
Parent naturalized on or after 3 October 1981 — no loss by naturalization
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. 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). A parent who naturalized as a US citizen after that date did not lose Portuguese nationality by doing so. If they were Portuguese when you were born, you may qualify once your birth is registered or you declare.
Parent lost Portuguese nationality before 3 October 1981 — Articles 30 and 31
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 declarationwhere 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. Under the 1959 law, losing Portuguese nationality by voluntarily taking another nationality did not extend to the person's children. Lei 2098 had other grounds of loss too, so get advice if another may apply.
Born before your parent naturalized?
If your parent naturalized as a US citizen after you were born, that later act does not change whether your parent was Portuguese at your birth. It does not make you Portuguese by itself, though: if you were born abroad, you become Portuguese by origin once your birth is inscribed in the Portuguese civil registry or you declare that you want to be Portuguese, and that counts from your birth (Article 11). If you were born before 3 October 1981, the note near the top of this page applies.
Documents you'll need
All US-issued documents require an apostille from the Secretary of State of the issuing state. You need a translation only if the conservador asks — documents in English are exempt by default (Regulamento art. 37.º n.º 2). Portuguese-issued documents generally do not need apostille or translation, and you need not supply Portuguese civil-registry certificates at all 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 itself (Regulamento art. 37.º n.º 4). You do not need a criminal record certificate on the parent path — that requirement belongs to the grandchild route.
Your documents
- Your birth certificate — long-form (full) birth certificate, 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)
- Your valid government-issued photo ID — passport, driver's license, or equivalent
- NOT required: a criminal record certificate. The Regulamento da Nacionalidade puts that requirement in art. 10.º-A n.º 3 al. c), which governs netos (grandchildren). The parent route is art. 8.º, and its n.º 2 states the whole of what you file — 'prova da nacionalidade portuguesa de um dos progenitores', proof that one parent is Portuguese. Lei Orgânica n.º 1/2026 confirms the split: art. 1.º n.º 3 attaches the art. 6.º n.º 1 al. c)–h) requirements to alínea d) only, never to alínea c). The IRN's own forms encode it too — Modelo 1D (grandchild) has a criminal-record section, Modelo 1C (child) has none. Do not spend money on an FBI check or apostilles for this path
Your parent's documents (the qualifying ancestor)
- Proof of your parent's Portuguese nationality — if your parent was born in Portugal, their Portuguese birth record (certidão de nascimento); if your parent was born abroad: their Portuguese birth record made by inscription, or the registered declaration (Article 21(4)). Instead of ordering the certificate, you may give details that identify the record and let the registry obtain it (Regulamento art. 37.º n.º 4)
- Parent's marriage certificate (if your parents are or were married to each other) — apostilled if US-issued; a translation only if the conservador asks (Regulamento art. 37.º n.º 2)
- Parent's naturalization certificate (if they naturalized abroad) — confirms the naturalization date, which decides whether the pre-1981 loss rules and Articles 30 and 31 come into play
- Parent's death certificate (if deceased) — apostilled if US-issued; a translation only if the conservador asks (Regulamento art. 37.º n.º 2)
Document note: name discrepancies
Americanized names are a common problem in Portuguese applications. If your parent's name was changed upon immigration — for example, “António” becoming “Anthony” or “Maria” becoming “Mary” — the name on their Portuguese birth record will differ from their US naturalization certificate. Document this discrepancy and, where possible, include any prior documents that show the name transition. Address it proactively rather than leaving it unexplained.
Processing time
Portugal publishes no processing time for the parent path. The document set is simpler than the grandparent path — no A2 certificate, no effective-connection evidence — but that shortens how long it takes you to assemble the file, not how long the registry takes to reach it. 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.
Priority is narrower than it sounds
The IRN's standing priority covers only files for minors born abroad to a Portuguese parent who have no other nationality and remain undocumented — which does not describe a child who holds US citizenship.
Urgency must be proved
Any applicant may ask for a file to be treated as urgent, but only on exceptional grounds they can prove — among them statelessness, a serious humanitarian situation, urgent life-threatening treatment available only to EU citizens, or being aged 75 or over. Portugal publishes no figure for how long other files take.
How you file — by post to a Balcão da Nacionalidade, online, or in person at a consulate — does not change your position in that queue. Full driver analysis →
2026 nationality law reform: does it affect the parent path?
Lei Orgânica n.º 1/2026 was approved by Parliament on April 1, 2026, signed by the President on May 3, 2026, and entered into force on 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 the parent route under Article 1(1)(c), the reform added Article 19(2): the registration that confers nationality now has constitutive effects. The new Article 1(3) requirements apply only to the grandchild route, not to the parent route. Naturalization residency requirement is now 10 years (general) or 7 years (CPLP nationals and EU citizens). That residence-length requirement (Article 6(1)(b)) does not apply to the descent routes under Article 1(1)(c)–(d) — though since 19 May 2026 Article 1(3) applies Article 6(1)(c)–(h) to the grandchild route.

Where to apply
gov.pt lists three ways to file for Portuguese citizenship through a parent: by post, online, or in person. A private applicant may post the file directly to a Balcão da Nacionalidade or hand it in at a consular post; the online channel is reserved to mandatários (lawyers and solicitors) because online filing has been mandatory for them since 1 December 2023. 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). Where you file changes the fee, not the queue: €175 direct to the IRN, or €220 (~$257) filed at a US consulate (a consular filing is charged under the Tabela de Emolumentos Consulares). Minors are free either way.
US Portuguese consulates — and their intake rules
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. runs a consular section too; 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.Read the post's own nationality page before booking, and confirm document requirements with it or at irn.justica.gov.pt.
Filing through a Portuguese lawyer — what it does and does not buy
A licensed Portuguese lawyer files through the IRN — Instituto dos Registos e do Notariado online channel because they are required to — it has been mandatory for mandatários since 1 December 2023. It is not a queue-jumping lane, and we previously said it was. What a lawyer genuinely offers is a complete file, fewer exigência cycles, and someone to chase a stuck case. Not a better place in line.
