Portugal's New Nationality Law (May 2026): What Changes for Citizenship

What changed and when it takes effect

On 1 April 2026 the Assembleia da República approved a sweeping revision of the Lei da Nacionalidade by 152 votes to 64. President António José Seguro promulgated the law and it was published in the Diário da República, entering into force on 4 May 2026. This is the largest single change to Portuguese citizenship rules in more than a decade and it affects almost every foreign resident planning to naturalise.

The new residency clocks

The headline change is the minimum period of legal residence required before you can apply for citizenship by naturalisation. The thresholds roughly double across every category, and the period is no longer measured from when you first applied — it now runs from the date your first residence permit (título de residência) was actually issued.

• Third-country nationals (non-EU, non-CPLP): 10 years (previously 5)
• EU citizens: 7 years (previously 5)
• CPLP nationals — Brazil, Angola, Mozambique, Cape Verde, Guinea-Bissau, São Tomé and Príncipe, Equatorial Guinea, East Timor: 7 years (previously 3)
• Residence must be continuous and uninterrupted — a lapsed permit can reset the clock
• Clock starts from the issue date of your first residence card, not your application date

The 'clock starts at permit issuance' trap

Under the previous regime, the residency count effectively began when you lodged your first residence application. From 4 May 2026 it begins on the date AIMA (or its predecessor SEF) actually issued your first residence card. With AIMA backlogs adding 6–18 months between application and card delivery, this single rule can push borderline applicants months or even years further from eligibility. Pull out your first título de residência and write down the issue date — that is now your real Day 1.

Tightened criminal record bars

The new law lowers the criminal threshold that disqualifies an applicant and expands the list of offences that can trigger loss of nationality once granted.

• A prison sentence of 3 years or more (previously 5) bars naturalisation
• A sentence of 5 years or more for certain serious crimes can trigger loss of already-acquired Portuguese nationality
• The qualifying offence list now includes leadership of criminal associations, arms trafficking and drug trafficking, in addition to aggravated homicide, slavery, human trafficking, rape and sexual abuse of minors
• The disqualification can apply to sentences handed down abroad in certain circumstances

Birthright citizenship is restricted

Children born in Portugal to foreign parents no longer acquire Portuguese citizenship at birth on a simple one-year residence rule. The new minimum parental residence is significantly longer.

• At least one CPLP-national parent must have been legally resident for 3 years before the birth
• At least one parent of any other nationality must have been legally resident for 4 years before the birth
• Previously, one year of parental residence was sufficient
• Children who do not qualify at birth can still naturalise later under the general rules

New civic knowledge requirement

In addition to the unchanged A2 European Portuguese language requirement, applicants must now demonstrate civic knowledge of Portuguese democratic institutions, history, and the rights and duties of citizenship, plus a formal commitment to democratic values. Implementing regulations — exact format, passing threshold, and administering body — are expected by decree-law in the months following entry into force. The A2 CIPLE exam (CAPLE) and the 150-hour PLA course remain the two accepted ways to prove language ability.

No transitional regime — the most controversial point

There is no grandfather clause. From 4 May 2026 the new rules apply in full to every new application — including residents who arrived years ago and structured their lives around the previous five-year timeline. The Socialist opposition pushed for transitional protections; PSD and Chega voted them down. Pending applications already filed with the IRN before 4 May 2026 remain protected by the principle that the rules in force at lodgement govern the case, but anyone who had not yet submitted on that date now falls under the new regime.

Old law vs new law — at a glance

A side-by-side view of what changed on 4 May 2026.

• General residency: 5 years → 10 years
• EU nationals: 5 years → 7 years
• CPLP nationals: 3 years → 7 years
• Clock starts: application date → first permit issue date
• A2 Portuguese: required → required (unchanged)
• Civic knowledge test: not required → required
• Criminal bar: higher threshold → 3-year sentence disqualifies
• Loss of nationality for serious crimes: limited → expanded list, 5-year sentence trigger
• Birthright (jus soli): 1 year parental residence → 3 years (CPLP) / 4 years (others)
• Transitional regime: n/a → none — old rules apply only to applications already lodged

Pending applications: are you protected?

If your file was formally lodged with the Instituto dos Registos e do Notariado (IRN) before 4 May 2026, your case is processed under the previous five-year regime — even if the decision arrives years later. Roughly 40,000–60,000 cases were sitting in the queue when the law took effect. You do not need to top up your file to comply with the new 10-year rule. Continue responding to IRN requests for documentation and keep proof of submission (receipt, reference number, email confirmations) in a safe place in case the file is later questioned.

What to do based on where you are

Your urgency depends on how far along the residency path you already are. Use this as a starting point and confirm with an immigration lawyer before acting.

• Already 5+ years of legal residence and ready to file: you missed the pre-promulgation window — file now anyway only if you previously qualified and have evidence your application was lodged before 4 May; otherwise the 10-year rule applies
• Pending application already with the IRN: protected, no action needed on the timeline; respond promptly to any document request
• CPLP national with 3–6 years: re-plan around the 7-year track from your first permit issue date
• EU national with 5–6 years: re-plan around the 7-year track
• Non-EU, non-CPLP under 10 years: consider permanent residence (still available after 5 years of legal residence) as an interim status with most of the practical rights short of voting and a passport
• Children born in Portugal after 4 May 2026: confirm at least one parent meets the new 3- or 4-year parental residence threshold; otherwise plan for naturalisation later

Permanent residence is now more attractive

Permanent residence (autorização de residência permanente) was not changed by this reform. It still becomes available after 5 years of legal residence, has no renewal cycle in the same sense as the temporary card, and grants almost all practical rights — work, SNS access, family reunification, EU long-term resident status — short of voting in national elections and holding a Portuguese passport. For many residents now staring down a 10-year wait for citizenship, permanent residence becomes the primary medium-term goal.

What stayed the same

Despite the political noise, several core elements were not touched.

• A2 European Portuguese language requirement (CIPLE or PLA 150-hour course)
• Citizenship by descent (jus sanguinis) for children of Portuguese citizens
• Sephardic Jewish heritage route — still closed to new applications since 2024 reforms, no further change
• Marriage / união de facto route to nationality (with its own residency conditions)
• Permanent residence eligibility at 5 years
• The right of pending applicants to be judged under the rules in force when they applied

Documents you should already have on file

Whatever timeline now applies to you, the documentary trail is the same and gets harder to reconstruct the longer you wait. Build the file as you go.

• First and all subsequent títulos de residência (keep PDFs and photos of every card)
• AIMA appointment confirmations, receipts, and any proof of attempted bookings during backlog periods
• A2 language certificate (CIPLE from CAPLE, or PLA 150-hour course certificate)
• Portuguese criminal record (Certificado de Registo Criminal) — issued close to filing
• Criminal record from your country of birth and any country lived in over the past 5 years (apostilled, translated)
• NIF registration with Autoridade Tributária and proof of Portuguese tax filings
• NISS number and Social Security contribution history if employed or self-employed
• Proof of Portuguese residential address (utility bills, lease, atestado de residência)
• Valid passport

FAQ

The questions we are seeing most in the AskPortugal community since the law was signed.

• Does the new law apply to me if I arrived in 2022? Yes — unless you formally lodged a citizenship application before 4 May 2026, the new residency clock applies
• I'm Brazilian — do I really now wait 7 years instead of 3? Yes, CPLP nationals are now on the 7-year track measured from first permit issuance
• Did the A2 language requirement change? No — it is unchanged. CIPLE or PLA 150-hour certificate still apply
• Do native Portuguese speakers from CPLP countries get a language exemption? No — CAPLE assesses European Portuguese specifically
• Will the Constitutional Court strike this down? Possibly in part. The lack of transitional protection and the loss-of-nationality provisions are the most exposed; expect litigation through 2026–2027
• Can I still get permanent residence at 5 years? Yes — permanent residence rules were not changed
