Portuguese citizenship law changes frequently — the information below reflects publicly reported sources as of May 26, 2026 and may not reflect subsequent developments.

How we source this page

Every factual claim links to a primary Portuguese government source (Diário da República at dre.pt, IRN at irn.justica.gov.pt) or to a reputable secondary source (Portuguese law firm analysis, immigration-specialist news outlets such as IMI Daily, Immigrant Invest, Outbound Investment). We do not conduct primary interviews, attend parliamentary sessions, or make independent legal determinations.

1. What happened: Lei Orgânica n.º 1/2026

According to Diário da República and corroborating coverage by IMI Daily, Outbound Investment, and Immigrant Invest, Portugal's Parliament approved Lei Orgânica n.º 1/2026 on April 1, 2026 by a two-thirds majority. The President signed the law on May 3, 2026. It was published in Diário da República n.º 95/2026 on May 18, 2026 and entered into force on May 19, 2026.

The reform is the most significant change to Portugal's Lei da Nacionalidade (Law 37/81) in over a decade. It came after an earlier October 2025 draft was ruled partially unconstitutional by Portugal's Constitutional Court in a December 15, 2025 decision (see Section 3 for background). Parliament redrafted the bill, removing or revising the unconstitutional provisions, and re-approved it on April 1, 2026.

The reform makes three substantive changes that affect would-be applicants. None of the three modifies the pure descent paths under Article 1(1)(b) (child of a Portuguese citizen) or Article 1(1)(d) (grandchild of a Portuguese citizen). The A2 CIPLE language requirement for the grandparent path is unchanged. Processing times at the Conservatória dos Registos Centrais (CRC) in Lisbon have not been adjusted by the law itself.

How the reform has been reported

“The reform doubles the general naturalization residency requirement from 5 to 10 years and from 3 to 7 years for CPLP nationals and EU citizens, with the residency clock running from the issuance of the first residence permit.”

“Portugal's President has signed the revised nationality law, doubling the citizenship timeline to ten years and closing the Sephardic Jewish descent route to new applicants under transitional provisions for cases already filed.”
IMI Daily (Investment Migration Insider) — As reported following the presidential signing. Source
“The signing of the revised nationality law extends the standard citizenship timeline to ten years and introduces a new great-grandchild descent route conditioned on five years of legal residence in Portugal — not a pathway exercisable from outside Portugal.”
Outbound Investment news desk — Reporting on the May 3, 2026 presidential signature. Source
“Pure descent paths — claims under Article 1(1)(b) for children of a Portuguese citizen and Article 1(1)(d) for grandchildren of a Portuguese citizen — are not changed by Lei Orgânica n.º 1/2026. The A2 language requirement for the grandchild path remains in force.”
Global Citizen Solutions advisory — As summarized in their Portuguese nationality law update. Source
“The revised law was redrafted after the Constitutional Court found portions of the original October 2025 draft partially unconstitutional in December 2025. The version signed by the President in May 2026 reflects those constitutional revisions.”

2. The three substantive changes, explained

(1) Sephardic Jewish descent route closed to new applicants

Per Valadas Coriel & Associados analysis and IMI Daily reporting, the Sephardic Jewish descent route originally created by Law 30-E/2015 and modified by Law 1/2024 is closed to new applicants as of May 19, 2026. Lei Orgânica n.º 1/2026 includes transitional provisions allowing applications filed before that date to continue under the prior rules — what those provisions require in practice depends on the stage of the filing and on how the IRN implements them. Applicants in pending Sephardic cases, or those who had begun gathering documents but had not yet filed, should consult a Portuguese immigration attorney who specializes in Sephardic applications.

(2) Great-grandchild descent route added — with a 5-year Portuguese residence requirement

Per Outbound Investment and Lincoln Global Partners analysis, the reform adds a new descent route for great-grandchildren of a Portuguese citizen — a generation previously without a direct descent pathway. The new route requires three things: (a) a B1 Portuguese language certificate (one level above the A2 required of grandchildren), (b) demonstrated effective connection to the Portuguese community, and (c) five years of legal residence in Portugal. Because the third requirement means physically relocating to Portugal under a residence permit, this is not a US-based DIY pathway. For most great-grandchildren of Portuguese ancestry in the US, the practical eligibility position is unchanged.

(3) Naturalization residency requirement doubled

Per Valadas Coriel, IMI Daily, and Global Citizen Solutions, the residency requirement for naturalization was doubled from 5 to 10 years on the general track, and from 3 to 7 years for nationals of CPLP countries (Comunidade dos Países de Língua Portuguesa) and EU citizens. The residency clock runs from the issuance of the first residence permit. This change applies to the naturalization pathway — a separate route from citizenship by descent — and does not affect descent applicants under Article 1(1)(b) or Article 1(1)(d).

What did NOT change

The parent descent path under Article 1(1)(b) is unchanged — citizenship still transmits automatically at birth when one parent was a Portuguese citizen at the time of the applicant's birth, with no language requirement and no residence requirement. The grandparent descent path under Article 1(1)(d) is unchanged — the A2 CIPLE language requirement and the demonstrated effective connection (ligação efetiva) requirement both remain in force. The chain-breaker analysis for pre-1981 naturalization, under Article 30 of Law 37/81, is unchanged.

4. What this may mean for applicants

The four scenarios below describe how different applicant situations may be affected by Lei Orgânica n.º 1/2026. If you are currently applying for Portuguese citizenship and your eligibility depends on any of these questions, consult a licensed Portuguese citizenship attorney for guidance on your specific situation.

I was planning to apply via Sephardic descent

The Sephardic Jewish descent route originally created by Law 30-E/2015 (modified by Law 1/2024) is closed to new applicants as of May 19, 2026. Pending applications filed before that date may continue under transitional provisions — what those require in practice depends on the stage of the filing and on IRN implementation guidance. New filings are no longer accepted. Consult a Portuguese immigration attorney who specializes in Sephardic applications about whether your specific situation falls within the transitional provisions.

I qualify through a parent or grandparent

Pure descent paths under Article 1(1)(b) (parent) and Article 1(1)(d) (grandparent) are not affected by Lei Orgânica n.º 1/2026. If your parent was a Portuguese citizen at the time of your birth, the parent path rules are unchanged. If you are claiming through a Portuguese-born grandparent, the A2 CIPLE language requirement, the effective connection (ligação efetiva) requirement, and the pre-/post-1981 chain-breaker analysis under Article 30 of Law 37/81 all remain in force as before.

I have Portuguese great-grandparent ancestry

A new great-grandchild descent route was added by Lei Orgânica n.º 1/2026, but it requires a B1 Portuguese language certificate, demonstrated effective connection to the Portuguese community, and five years of legal residence in Portugal. Because the third requirement involves physically relocating to Portugal under a residence permit, this is not a US-based DIY pathway. The two-step strategy (your grandparent establishes citizenship first, then your parent claims through them, then you claim through your parent) may still be available under the existing Lei 37/81 framework for some families — consult a Portuguese immigration attorney.

I'm in the naturalization process

The naturalization residency requirement was doubled — from 5 to 10 years on the general track, and from 3 to 7 years for CPLP nationals and EU citizens. The residency clock runs from the issuance of the first residence permit. Lei Orgânica n.º 1/2026 may include transitional provisions for cases at different stages of the naturalization process; how the IRN implements those provisions affects whether time already accrued under the prior rules counts toward the new threshold. Consult a Portuguese immigration attorney about your specific filing status.

5. What we're watching next

Lei Orgânica n.º 1/2026 is now in force. The implementation details — especially how the IRN administers the transitional provisions for pending Sephardic and naturalization cases — will become clearer over the coming weeks and months as guidance is published.

  • IRN implementation guidance. The Instituto dos Registos e do Notariado is expected to publish operational guidance on the transitional provisions of Lei Orgânica n.º 1/2026 — particularly for pending Sephardic applications and for naturalization cases mid-clock under the prior 5-year and 3-year rules. This page will be updated when published guidance is available at irn.justica.gov.pt.
  • Implementation of the great-grandchild route. The new great-grandchild descent route requires B1 Portuguese certification, effective connection, and 5 years of legal residence in Portugal. The B1 exam infrastructure and the effective-connection evidentiary standard for this route will need to be clarified. Because this is not a US-based DIY pathway, it is unlikely to be a primary path for most descendants of Portuguese ancestry in the US.
  • Possible follow-up litigation. Major nationality law reforms in EU member states often attract subsequent constitutional challenges and EU-law challenges (e.g., questions about whether new restrictions comply with EU citizenship principles). No such challenges are publicly reported as of May 26, 2026. This page will track any that emerge.
  • Processing time changes at CRC Lisbon. Lei Orgânica n.º 1/2026 does not directly modify CRC processing times. However, a sustained shift in application volume — for example, fewer Sephardic filings, more pre-deadline rush filings — could indirectly affect queue length. Current estimates (9–18 months on the parent path; 18–42 months attorney-submitted or 2–4 years consulate-submitted on the grandparent path) remain the baseline.

7. Frequently asked questions

Does this law affect my parent descent application?

No. Lei Orgânica n.º 1/2026 does not change the Article 1(1)(b) parent descent path. If your parent was a Portuguese citizen at the time of your birth, you acquired Portuguese citizenship at birth — the rules described on the parent path page continue to apply. Registration with a Portuguese consulate or via the IRN digital platform proceeds under the existing Lei 37/81 framework.

I was planning to apply through the Sephardic track — what now?

As of May 19, 2026, the Sephardic Jewish descent route (originally Law 30-E/2015, modified by Law 1/2024) is closed to new applicants. Applications filed before May 19, 2026 may continue under transitional provisions in Lei Orgânica n.º 1/2026 — what those provisions require in practice depends on the stage of your filing and on how the IRN implements them. If you had a pending Sephardic application or had begun gathering documents but had not yet filed, consult a Portuguese immigration attorney who specializes in Sephardic applications. This is not a DIY pathway under either the prior or current law.

Can I now apply as a great-grandchild?

Lei Orgânica n.º 1/2026 added a new great-grandchild descent route, but it is not a US-based DIY pathway. The new route requires: (1) a B1 Portuguese language certificate (one level above the A2 required of grandchildren), (2) demonstrated effective connection to the Portuguese community, and (3) five years of legal residence in Portugal. Because the third requirement means physically relocating to Portugal under a residence permit, US-based descendants typically cannot exercise this route directly. If you are already living in Portugal or planning to, consult a Portuguese immigration attorney about how the new route applies to your case.

Does the 10-year residency change affect me?

It depends on your path. If you are claiming citizenship by descent through a parent (Article 1(1)(b)) or grandparent (Article 1(1)(d)), the 10-year residency rule does not apply — those are pure descent paths that do not require residence in Portugal. The 10-year requirement (and the 7-year requirement for CPLP nationals and EU citizens) applies to the naturalization track, which is a separate pathway for people who do not qualify by descent and are instead seeking citizenship based on legal residence in Portugal. The residency clock runs from issuance of the first residence permit.

What was the Constitutional Court issue with the earlier version?

On December 15, 2025, Portugal's Constitutional Court ruled that portions of an earlier October 2025 draft of the nationality reform were partially unconstitutional. The law was redrafted and re-approved by Parliament on April 1, 2026 (by a two-thirds majority), signed by the President on May 3, 2026, published in Diário da República n.º 95/2026 on May 18, 2026, and entered into force on May 19, 2026 as Lei Orgânica n.º 1/2026. The version now in effect reflects the constitutional revisions made after the December 2025 ruling.
