Portuguese citizenship changed more in 2026 than it had in a decade. A new Nationality Law came into force on 19 May 2026, extending the residency most people need before they can naturalise and adding a language requirement across the board. The routes that run through ancestry, meanwhile, were largely left alone. If you have been reading older guides that promise citizenship “after five years,” set them aside — that number is gone. Here is the accurate 2026 picture, route by route.
Three main doors lead to a Portuguese passport: descent, naturalisation (living here long enough), and marriage or partnership with a Portuguese national. Which one fits you depends less on where you live now and more on your family tree and your paperwork.
Citizenship by Descent
If you have Portuguese ancestry, this is usually the fastest and cheapest route, because it does not require you to live in Portugal at all. It splits by generation.
Through a parent. If either of your parents was a Portuguese citizen when you were born, you are generally entitled to citizenship by attribution — you are considered Portuguese from birth, and the process is essentially registering something that is already true. You transcribe your birth into the Portuguese civil registry. This is an entitlement, not a discretionary grant, which makes it the most secure descent claim.
Through a grandparent. If a grandparent was a Portuguese citizen but your parent was not registered, you apply under the Article 6 route. There is no residency requirement, but the bar is higher than the parent line: you must prove the lineage with civil records, demonstrate effective ties to the Portuguese community, and — this is the part that catches people — show A2-level Portuguese. Crucially, the 2026 law did not curtail this grandparent route, so it remains open on broadly the same terms.
Descent cases live or die on documents. You are assembling an unbroken chain of birth, marriage and sometimes death certificates linking you to your Portuguese ancestor, often decades old and held in a parish or conservatória somewhere in Portugal. Locating and legalising those records is the real work. Our dedicated citizenship by descent guide walks through exactly which certificates you need and how to trace them.
Citizenship by Naturalisation
This is the route for people with no Portuguese blood who move here, build a life, and want to become citizens. It is also where the 2026 changes bite hardest.
Under the new law, you can apply for naturalisation after:
- Seven years of legal residence if you are a national of an EU member state or of a Portuguese-speaking (CPLP) country — Brazil, Angola, Mozambique, Cape Verde, Guinea-Bissau, São Tomé and Príncipe, East Timor.
- Ten years of legal residence for all other nationalities.
That is up from the previous five years, and it is the single most important thing to understand about citizenship in Portugal today. On top of the residency, you must:
- Demonstrate A2-level Portuguese, typically via the CIPLE exam or a recognised course certificate.
- Have no relevant criminal record — the threshold was tightened in 2026.
- Show effective ties to the national community.
One more detail that matters enormously for planning: the residency clock starts from the date your residence permit is issued, not from when you first set foot in the country or applied. Time spent waiting on an AIMA appointment before your permit is granted does not count. The old Sephardic-Jewish naturalisation route was abolished under the same reform.
Applications filed before 19 May 2026 are assessed under the old rules, so anyone who got in ahead of the deadline is grandfathered onto the five-year timeline. Everyone else is now on seven or ten.
Citizenship by Marriage or Partnership
Marry or enter a registered civil partnership (união de facto) with a Portuguese citizen and you open a separate route. You can apply after three years of marriage or partnership. You do not have to have lived in Portugal for those three years, but the longer and more genuine the connection — and the stronger your ties to the community — the smoother the process.
You will still need to show A2 Portuguese and a clean criminal record, and the authorities scrutinise the relationship to guard against marriages of convenience. Documentation of a shared life — joint finances, cohabitation, time together — supports the application.
Documents and How to Apply
Whatever the route, most applications share a common core:
- Your birth certificate, and the relevant ancestor’s or spouse’s Portuguese civil records.
- Marriage or partnership certificates where relevant.
- A criminal-record certificate from every country you have lived in as an adult, apostilled and translated.
- Proof of A2 Portuguese (exam certificate or course completion).
- For naturalisation, evidence of your legal residence period.
- Payment of the applicable fee, which varies by application type.
Foreign documents almost always need an apostille (under the Hague Convention) and a certified Portuguese translation.
Applications are handled by the IRN — Instituto dos Registos e do Notariado. In practice, lawyers and solicitadores must submit through the online nationality platform, while individuals applying without a representative can go by post or through a Balcão da Nacionalidade. The official overview and current fees live on the Justiça / IRN nationality pages.
Be realistic about timelines. Even straightforward descent cases commonly take 12 to 24 months, and complex or heavily backlogged files run longer. The IRN was working through significant volumes in 2026 as the new law bedded in.
Common Mistakes
- Believing the “five-year” figure. For new naturalisation applications it is now seven or ten years.
- Ignoring the language requirement. A2 Portuguese now applies across descent, marriage and naturalisation — start learning early.
- Missing a certificate in the chain. A single unlocatable birth or marriage record can stall a descent case for months.
- Miscounting residence. The clock runs from permit issuance, not arrival.
- Skipping apostilles. Uncertified or untranslated foreign documents get rejected.
Short FAQ
Does Portugal allow dual citizenship? Yes. You can become Portuguese without renouncing your existing nationality.
Can my children become citizens too? Often yes — minor children of a naturalising or descent applicant have their own routes; check the specific provisions.
Do I need to speak fluent Portuguese? No — the standard is A2, a basic conversational level, not fluency.
I have a Portuguese grandparent — do I have to move to Portugal? No. The grandparent (Article 6) route has no residency requirement, but you must prove lineage, effective ties and A2 Portuguese.
What if I applied before 19 May 2026? Your application is assessed under the old rules, including the five-year residency period.
Where you go from here depends on your route. If ancestry is your path, start with the descent guide. If you are moving here to eventually naturalise, the residence permits guide and our visa options show how to get the permit that starts your clock. As always, citizenship decisions rest with the IRN, and no one can guarantee an outcome — but a complete, correctly legalised file is what moves cases forward.
