Portugal Raises Citizenship Residency Requirement from Five to Ten Years

Portugal has enacted a significant reform to its nationality law, doubling the residency requirement for naturalization from five years to ten for most foreign nationals. President António José Seguro signed the revised Nationality Law on May 3, 2026, following a lengthy legislative process that included parliamentary votes, a Constitutional Court review, and a second round of parliamentary approval. The law takes effect upon publication in the Diário da República, which is expected within 30 days of the presidential signature.

Legislative Background

The reform originated in June 2025, when the Portuguese government presented a draft law proposing amendments to the existing Nationality Law (Law No. 37/81). The stated objective was to align Portugal's naturalization standards more closely with those of other European Union member states and to strengthen integration requirements for prospective citizens.

Parliament approved an initial version of the amendments in October 2025, but the Constitutional Court intervened in December of that year, striking down four provisions it found incompatible with the constitution. Among those was a clause that would have applied the new residency timelines retroactively to pending applications, which the Court ruled violated the principle of legitimate expectations. A revised version was brought back to parliament in April 2026, passing with a two-thirds majority, before receiving presidential assent.

Key Changes Under the New Law

The central change is a tiered extension of the legal residency period required before a foreign national may apply for Portuguese citizenship through naturalization. Most non-EU nationals, including citizens of the United States, the United Kingdom, Canada, and other countries outside the EU and CPLP, now face a 10-year requirement. Nationals of EU member states are subject to a 7-year requirement, up from five. Citizens of CPLP countries (the community of Portuguese-speaking nations, which includes Brazil, Angola, Cape Verde, Mozambique, and others) also move to 7 years, up from a prior preferential threshold of 3 years.

The law also changes when the residency clock begins. Going forward, the qualifying period is counted from the date Portugal's Agency for Integration, Migration and Asylum (AIMA) issues the physical residence permit, reversing a 2024 amendment that had started the clock at the application submission date. Given that AIMA currently holds a backlog of an estimated 40,000 to 60,000 citizenship cases, the gap between submission and issuance can span many months, effectively extending the wait beyond the stated 10-year baseline for some applicants.

In addition, the new law introduces a civic and cultural knowledge test as part of the naturalization process, complementing the existing requirement of A2-level proficiency in European Portuguese. A separate provision that would have allowed citizenship revocation for naturalized citizens convicted of serious crimes was struck down by the Constitutional Court and is not part of the enacted legislation.

Government Rationale and Broader European Context

Portuguese officials have framed the reform as an integration measure, aimed at ensuring that citizenship applicants have a sustained and genuine connection to Portugal rather than a minimal legal foothold. Golden Visa investors, who represent a comparatively small portion of overall immigration numbers, were not cited as the primary policy target.

Portugal's move is consistent with a broader trend across Europe toward stricter naturalization standards. Germany repealed its three-year fast-track naturalization pathway in October 2025, though its standard five-year route remains in place. The Netherlands has proposed extending its own timeline to ten years. Italy has tightened restrictions on ancestry-based citizenship. Spain discontinued its Golden Visa program in 2025. Portugal joins this shift while still maintaining residency pathways that are considered relatively accessible within the European context.

Implications for Current and Prospective Applicants

The Constitutional Court's ruling ensures that pending applications will not be subject to the new requirements. Individuals who submitted citizenship applications before the law's publication date will have their cases assessed under the previous five-year standard.

Residents who are between two and four years into their legal residency and had planned around a five-year pathway face the most uncertain situation. No grandfathering provisions are included in the current law, and legal challenges from affected residents, including a case filed by Golden Visa investors at the Constitutional Court in late 2025, remain pending.

Golden Visa holders retain their existing residency rights in full. Permanent residency remains available after five years of qualifying investment, and the program's minimal physical presence requirement is unchanged. What has shifted is the timeline to citizenship eligibility, which for investors who entered the program with naturalization as a long-term objective now extends considerably further.

When signing the law, President Seguro noted two concerns: that applicants with pending cases should not be prejudiced by the change, and that administrative delays attributable to state agencies should not be counted against applicants' residency timelines. These statements carry no binding legal force but may inform future judicial proceedings on the matter.

Practical Considerations on Timing

Legal practitioners have observed that the 10-year figure may understate the effective timeline for many applicants. Because the residency clock begins at permit issuance, and AIMA's processing delays can run from several months to well over a year, applicants starting the process now may not become eligible to apply for citizenship for 11 to 12 years or more. The citizenship application process itself has historically added further time on top of that.

What Remains Unchanged

Permanent residency, which is distinct from citizenship, continues to be available after five years of legal residence and confers the right to live and work in Portugal without periodic permit renewals. The A2 Portuguese language requirement remains in place for all naturalization applicants. The Golden Visa program continues to operate under its existing framework. Portugal's broader residency visa offerings, including the D7 passive income visa and other long-stay routes, are unaffected by the nationality law changes.

Applicants who are at or near the five-year mark are advised by immigration lawyers to file their citizenship applications before the law is published in the Diário da República, as applications lodged prior to that date will be governed by the previous rules. Those earlier in the residency process are encouraged to maintain thorough documentation of permit application and issuance dates, as the precise start of the qualifying period may be subject to scrutiny under the new framework.
