The Deadline Has Passed: What Happened
As of 20 August 2026, Portugal has not published the updated Regulamento da Nacionalidade, and the legal deadline to do so has now passed. Lei Orgânica n.º 1/2026 — the reform that raised the naturalization residency requirement to 7 years for EU and CPLP nationals and 10 years for everyone else — was published in the Diário da República on 18 May 2026 and entered into force on 19 May 2026. The law obliged the government to update the implementing regulation, the Regulamento da Nacionalidade (Decree-Law n.º 237-A/2006), within 90 days of publication. Counting 90 days from 18 May places that statutory deadline at around 16-17 August 2026. That window has closed with no regulation issued.
This is a change of state, not a change of law. Nothing about the naturalization requirements themselves has shifted: the longer residency periods, the civic knowledge test, and the permit-issuance clock were all in force from 19 May and remain so. What has changed is that the government is now past its own deadline for telling IRN (the Instituto dos Registos e do Notariado) precisely how to apply those requirements. Legal commentators tracking the reform had flagged mid-August as the trigger date; one immigration practice noted the government had until mid-August 2026 to issue the updated implementing regulation and that it remained pending in the days before the deadline (Lamares, Capela & Associados). With the date now behind us and the Diário da República still showing no updated Regulamento, applicants filing under the new law are operating in a defined-by-statute but undefined-by-procedure gap.
Why a Missing Regulamento Creates Legal Uncertainty
Portuguese citizenship runs on two instruments working together. The Lei da Nacionalidade sets out who qualifies and under what conditions; the Regulamento da Nacionalidade tells the registry how to assess and verify those conditions — which documents are accepted, which forms are used, how a requirement is tested, and how a pass or fail is recorded. When the law changes but the Regulamento does not, IRN officers are left with an instruction to assess something the law now requires, but without the standardized procedure that normally tells them how. That is the situation for every citizenship application filed on or after 19 May 2026.
The practical consequence of that gap is inconsistency. In the absence of a common procedure, individual IRN offices and officers must exercise discretion, and discretion produces divergence: one conservatório may suspend or hold new-law files until the Regulamento arrives, another may accept them and apply a provisional interpretation, and a third may request documents that a fourth does not. For an applicant, this means the outcome of a file can depend as much on which office handles it and when as on the strength of the file itself. It also raises the risk of a suspension or a request-for-documents (pedido de elementos) that stalls the process. None of this makes the new law unenforceable — it simply makes its early application uneven, which is exactly the problem an implementing regulation exists to prevent.
What Stays Undefined Without the Regulamento
The single most consequential undefined area is the civic knowledge and integration requirement. Lei Orgânica 1/2026 states that applicants must demonstrate sufficient knowledge of Portuguese language, culture, history and national symbols, along with the fundamental rights and duties of Portuguese nationality and the political organization of the Portuguese State. But the law does not itself specify the test: who administers it, what curriculum it covers, what the passing threshold is, whether the existing A2 language certificate satisfies the language portion, and which applicants are exempt. All of that was left to the Regulamento. Until it publishes, the civic knowledge requirement exists as a legal obligation with no examinable format — IRN cannot definitively test what has not been procedurally defined.
Two further areas stay open. The first is the evidence standard for "effective connection to the national community" (ligação efetiva à comunidade nacional) — a naturalization pillar that historically accepted employment, tax compliance, property, school enrolment, and civic involvement as proof, and which the reform's stricter integration philosophy may recalibrate. The second is the procedural machinery for verifying the new residency clocks: how IRN confirms that the 7 or 10-year period runs from the date AIMA issued your first residence permit rather than your entry or application date — a distinction that matters enormously given that many residents wait 18 to 24 months for a first card because of AIMA processing delays. Our companion guide on how the citizenship clock is calculated under the 2026 law covers that calculation, and the background primer on what the Regulamento is meant to define maps the full list of open questions.
Who Is Affected Right Now
The transitional rule is the dividing line. Any citizenship application filed at IRN before 19 May 2026 continues under the prior five-year residency rule and the existing Regulamento — those applicants are unaffected by both the new law and the missing regulation, and should simply continue their process. The applicants exposed to the gap are those filing on or after 19 May 2026, because their files fall under Lei Orgânica 1/2026 in full, including the parts the Regulamento was supposed to operationalize. If you submitted after that date, or are preparing to, you are the reader this situation directly concerns.
Within that group, the sharpest impact falls on people who were close to the old five-year mark, missed the 19 May window, and are now rebuilding their file under the 7 or 10-year framework. For them, the Regulamento's definition of the civic test and the connection-evidence standard determines what they need to assemble — and the missed deadline delays that clarity. EU and CPLP nationals, including Brazilians, who have already held seven years of permit-backed residence are technically eligible under the new framework, but in practice most IRN offices are expected to wait for the updated Regulamento before accepting these applications under the new 7-year standard. If your rule cohort is uncertain, our guide on which residency rule applies to your situation walks through the grandfathering logic in detail.
How to Protect Your Citizenship File in the Gap
The most important move right now is documentary discipline. If you file, or have filed, on or after 19 May 2026, keep dated proof of every interaction: the submission receipt, the reference number, and any acknowledgment or request from IRN. If your file is held or delayed pending the Regulamento, that paper trail establishes your date of submission — which can matter for how your application is ultimately assessed and for any later complaint about undue delay. Note explicitly in your file that you are proceeding under the new law with awareness that the implementing Regulamento is pending. This is not defensiveness; it is standard practice when a procedure is applied in a regulatory vacuum.
Beyond record-keeping, build the parts of the file that are already defined and will not change with the Regulamento. First, calculate your residency clock precisely from the issuance date on your first AIMA residence card — if that card is dated 3 June 2022, your 10-year clock reaches 3 June 2032, or your 7-year clock (EU/CPLP) reaches 3 June 2029 — and keep a copy of the card in your file. Second, obtain your A2 Portuguese language certificate if you do not already hold one; the requirement predates the 2026 reform, is procedurally settled, and IRN already accepts it, as our A2 course and certificate guide explains. Third, assemble your effective-connection evidence now: continuous employment or self-employment records, Portuguese tax returns, lease or property documents, children enrolled in state schools, SNS healthcare use, and any civic or association involvement. Collecting these before the Regulamento sets the exact thresholds means you enter the process with a strong file whenever the procedure is finalized, rather than starting from zero once it publishes.
What Happens When the Regulamento Finally Publishes
When the updated Regulamento does appear in the Diário da República — which, based on how Portugal has handled comparable implementing-regulation delays, is a matter of weeks or a few months rather than an indefinite wait — the procedural picture snaps into focus. The most concrete addition will be the civic knowledge test: expect the Regulamento to establish a formal test format, identify the body that administers and scores it, clarify whether the A2 certificate covers the language component, define the passing threshold, and list exemptions (for example, elderly applicants or those with documented disabilities). It should also confirm the evidence standard for effective connection and the procedure IRN uses to verify the permit-issuance residency clock. At that point, files that were held pending the regulation should begin moving again under a single, standardized process.
For most people filing under the new law, the Regulamento's publication is a reference point, not a filing trigger. Applications under the 7 and 10-year rules will not be filed in large numbers until the first post-May 2026 cohorts actually reach their residency minimum, which for many is years away. What the Regulamento does is remove the current uncertainty about what IRN will require — turning "we don't yet know the test format" into a defined checklist. Until it publishes, monitor the Diário da República at diariodarepublica.pt, keep your file current, and treat the missed deadline as a delay in procedure, not a change in your underlying eligibility. If you filed after 19 May and your process stalls, the post-in-force filing checklist covers the documentation and follow-up steps that keep a new-law application on track.
Frequently Asked Questions
The Q&A above answers the questions applicants are asking most as the deadline lapses: whether the Regulamento has been published, what happens to an application filed under the new law, whether the government can still be compelled to issue the regulation, whether you should wait before preparing your file, and whether the missed deadline changes the required residency period. The short version: the naturalization law is fully in force, the residency periods and the A2 requirement are settled and unaffected, and the missing Regulamento delays procedure — not eligibility. Build the defined parts of your file now, keep dated proof of every IRN interaction, and watch the Diário da República for the regulation's publication.
