Why the Regulamento Matters: Law vs Procedure
Portuguese citizenship is governed by two separate instruments: the Lei da Nacionalidade (Nationality Law), which sets out who is eligible and under what conditions, and the Regulamento da Nacionalidade, which specifies the administrative procedures through which that eligibility is assessed and verified. Lei Orgânica n.º 1/2026 significantly changed the eligibility requirements — extending the minimum residency period, introducing a civic knowledge test, changing how the residency clock is calculated — but those changes only become practically applicable once the Regulamento is updated to tell IRN (the Instituto dos Registos e do Notariado) exactly how to implement them.
Without an updated Regulamento, IRN officers processing applications filed after 19 May 2026 face a gap: the law tells them what to assess but not precisely how. The civic knowledge requirement, for example, is now legally mandated — applicants must demonstrate knowledge of Portuguese constitutional principles — but the test format, the responsible examining body, the passing threshold, the exemptions, and how to document compliance are all questions that the Regulamento will answer. Until it does, applicants and IRN offices are in a period of formal legal obligation with incomplete procedural guidance.
The 90-Day Deadline: When It Must Be Published
Article 14 of Lei Orgânica n.º 1/2026 gives the Council of Ministers 90 days from the law's publication date to update the Regulamento da Nacionalidade (Decree-Law n.º 237-A/2006, of 14 December 2006). The law was published in the Diário da República on 18 May 2026. Counting 90 days from 18 May places the statutory deadline around 17 August 2026 — approximately one month from the date of this guide.
Portuguese governments have historically complied with implementing regulation deadlines in the immigration and nationality space, though with occasional delays. If the government misses the August deadline, the law remains in force and IRN must continue processing applications — but without standardized guidance. In practice this tends to generate inconsistency: some IRN offices may suspend or delay applications pending the Regulamento; others may apply their own interpretation. Applicants in this window are advised to keep records of all submissions and, if applying from May 19 onwards, to note explicitly in their file that they are proceeding under the new law with awareness that the Regulamento is pending.
What the Regulamento Will Define
The updated Regulamento is expected to specify several areas left open by Lei Orgânica 1/2026. The most operationally significant are the civic knowledge and integration requirements. The law states that applicants must demonstrate, by test or certificate, sufficient knowledge of Portuguese language, culture, history and national symbols, as well as fundamental rights and duties inherent to Portuguese nationality and the political organisation of the Portuguese State. The Regulamento will need to define: the test curriculum and format, which body administers and grades the test, whether the A2 language certificate satisfies the language portion of this requirement (probable) or whether a separate civic test handles only the non-language components, how scores or certificates translate to a pass/fail determination at IRN, and what exemptions apply (for example, for elderly applicants or those with documented disabilities).
The Regulamento will also need to address the updated evidence standards for "effective connection to the national community" (ligação efetiva à comunidade nacional), which remains a legal ground for naturalization independent of the residency period. Previous versions of the Regulamento accepted employment in Portugal, property ownership, school enrolment for children, and demonstrated tax compliance as evidence of effective connection. It is expected that the updated Regulamento will retain or clarify these, though the threshold for what constitutes sufficient connection may be recalibrated to align with the stricter integration philosophy running through the 2026 reforms. Additionally, the Regulamento will update the procedural requirements for the new 7-year (EU and CPLP nationals) and 10-year (all others) cohorts — including how IRN verifies that the residency period runs from permit issuance, not application or entry.
Who Is Affected: Applications Filed After 19 May 2026
Any citizenship application filed at IRN on or after 19 May 2026 is governed by Lei Orgânica 1/2026 in full. The transitional provision in Article 13 protects applications that were already submitted to IRN before 19 May — those continue under the prior five-year residency rule and the prior version of the Regulamento. The new requirements — longer residency, civic knowledge test, permit-issuance clock — apply exclusively to filings from 19 May 2026 onwards.
The practical effect of the Regulamento gap is greatest for applicants who were eligible under the five-year rule, missed the May 19 window, and are now rebuilding their citizenship file under the new 7 or 10-year framework. For these applicants, the Regulamento's definition of the civic knowledge test and the evidence-of-connection standards will determine what documentation they need to start assembling. Waiting for the Regulamento to publish before beginning to compile that documentation wastes time — the evidence-gathering process for a 7 or 10-year citizenship file begins from the moment your first residence permit is issued.
EU and CPLP nationals (including Brazilians) who have held legal residence for at least 7 years from permit issuance are technically eligible to apply under the new framework once the Regulamento provides the procedural framework — but in practice, most IRN offices are expected to await the updated Regulamento before accepting applications under the new 7-year standard. If you fall into this group, monitor the Diário da República at diariodarepublica.pt and check with IRN directly after the August 2026 deadline passes.
What Citizenship Applicants Should Do Before August
The most important action before the Regulamento publishes is to calculate your residency clock accurately. Under Lei Orgânica 1/2026, the clock runs from the date your first residence permit was issued by AIMA — not from your entry date, your visa date, or the date you submitted your AIMA application. If your first residence card is dated 3 June 2022, your 10-year clock reaches 3 June 2032; your 7-year clock (if you are a CPLP or EU national) reaches 3 June 2029. Document this date from your physical residence card and keep a copy of it in your citizenship file. The post on how the citizenship clock works under the 2026 law explains the calculation in detail, including the impact of AIMA processing delays.
Second, obtain your A2 Portuguese language certificate if you do not already have one. This requirement was present in the pre-2026 law and carries forward; it is procedurally defined and IRN is already set up to receive it. Courses are available through state-subsidised providers including IEFP (Instituto do Emprego e Formação Profissional) and university language centres. The A2 course and certificate guide covers the approved providers and the certificate formats IRN accepts.
Third, begin building your effective-connection evidence file. Effective connection to the national community is both a standalone naturalization pathway and an evidentiary pillar of standard naturalization applications. Documents that have historically supported this case include: continuous employment records or proof of self-employment in Portugal, Portuguese tax returns showing residency and income, lease agreements or property ownership documentation, children enrolled in Portuguese state schools, social or civic involvement (association memberships, volunteer work, community organisations), and medical care through the SNS. Collecting and organising these documents now, before the Regulamento defines exactly what IRN will require, gives you a stronger starting file whenever you submit.
What Changes After the Regulamento Publishes
Once the updated Regulamento da Nacionalidade publishes — expected around 17 August 2026 — the procedural picture for citizenship applications filed after 19 May 2026 becomes clear. The most concrete changes will be in how the civic knowledge requirement is tested and verified. Based on the law's text and the government's stated policy direction, the Regulamento is expected to establish a formal civic knowledge test, likely administered by an IRN-affiliated body or through IEFP-accredited training providers. The test is expected to cover constitutional principles (the right to due process, the role of Parliament, the structure of government, fundamental rights), Portuguese history and national symbols (dates, events, and figures the law explicitly mentions), and civic duties (tax obligations, voting rights, mandatory education for children).
For applicants who are still years away from their 7 or 10-year residency minimum, the August Regulamento publication is the reference point for building the right evidence file — not a filing trigger. Applications under the new law will not be filed in large numbers until the first cohort reaches 7 or 10 years of permit-backed residency, which for most post-May 2026 applicants is many years away. What the Regulamento publication does is give those applicants a clear understanding of what evidence and test results IRN will require so they can plan accordingly. This is particularly relevant for applicants who entered Portugal in 2018 to 2022 under the old D7, D3, or job-seeker visa routes and whose first AIMA-issued card came in 2020 to 2023 — for them, the 10-year clock and the new Regulamento requirements are the operating framework for their eventual naturalization.
