TL;DR: ⚠️ Important update — April 2026: A new Nationality Law approved by the Portuguese Parliament increases the citizenship residency requirement from 5 years to 10 years for non-EU nationals (UK, US, Australia, Canada) and to 7 years for EU and CPLP nationals. The law is not yet in force as of May 2026 — publication in the Diário da República is pending. Pending applications submitted under the 5-year rule are protected by Constitutional Court ruling. For families starting their residency now, plan for 10 years before citizenship eligibility. Requirements: minimum 5 years of continuous legal residency, A2-level Portuguese language certificate, clean criminal record (both Portuguese and from your home country), and demonstrated connection to Portugal. The application is submitted at IRN (Instituto dos Registos e do Notariado) offices or online via the Portal SIMPLEX. Processing times run 12–24 months. Children born in Portugal to legal residents have a simplified path. Portuguese citizenship gives EU citizenship — one of the most significant benefits for UK and non-EU families post-Brexit.
Portuguese citizenship is the end-state goal for many expat families — and for good reason. A Portuguese passport is an EU passport, giving the right to live and work anywhere in the European Union. For British families in particular, who lost EU freedom of movement with Brexit, Portuguese citizenship restores what was lost and then some.
This guide covers the naturalisation route — the path to citizenship through residency — including the requirements, the process, the language test, and what happens to children along the way.
Why Portuguese Citizenship Matters for Expat Families
Beyond the emotional significance of belonging, Portuguese citizenship has concrete practical benefits:
- EU freedom of movement: the right to live, work, and study anywhere in the 27 EU member states — permanently, without visa applications or income thresholds
- Portuguese passport: one of the strongest passports in the world, visa-free or visa-on-arrival access to 185+ countries including the US (under ESTA)
- Dual citizenship: Portugal permits dual citizenship — you do not have to give up your existing passport. Check your home country’s rules — most (UK, Ireland, Australia, Canada, US) permit dual citizenship, but verify your specific situation
- Children’s future: children who acquire Portuguese citizenship can study at EU tuition rates across Europe and work freely across the EU throughout their adult lives
- Voting rights: Portuguese citizens can vote in Portuguese national elections and EU elections
The 5-Year Residency Requirement
The core requirement is 5 years of legal and continuous residency in Portugal. This means:
- Your residency must have been legal throughout — no gaps in visa or residence permit status
- Residency is counted from your first legal entry as a resident (your D7/D8 visa issue date, not your AIMA appointment date)
- Short absences from Portugal are permitted — the rule is that you should not have been absent for more than 6 consecutive months or more than 8 months in total during the 5-year period
- The 5 years must be immediately before your application — you cannot count residency from a previous stay if there was a significant gap
Keep your residency documents meticulously throughout the 5 years: all residence permits, all renewal documents, entry and exit stamps where possible, and any official correspondence with AIMA. These form the evidence trail for your application.
The Portuguese Language Requirement (A2 Level)
You must demonstrate Portuguese language proficiency at A2 level (the second level of the Common European Framework — basic conversational Portuguese). This is lower than many families expect — A2 is functional, not fluent. Most families who have lived in Portugal for 5 years and made any genuine effort with the language will be at or above A2 level.
How to prove A2 level:
- CIPLE (Certificado Inicial de Português Língua Estrangeira): the official A2 Portuguese language certificate issued by Camões Instituto da Cooperação e da Língua. This is the standard route and most immigration lawyers recommend obtaining this certificate even if you’re confident your Portuguese exceeds A2 — it removes all ambiguity from your application.
- Other recognised certificates: DIPLE (B2), DAPLE (C1) — any Portuguese language certificate at A2 or above is accepted. If you’ve taken Portuguese classes at a recognised institution that issues a certificate, check whether it’s accepted.
- Alternative evidence: in some circumstances, evidence of having completed Portuguese schooling or professional qualifications in Portuguese may be accepted. Discuss with your lawyer if you have relevant evidence that isn’t a formal language certificate.
Taking the CIPLE exam:
The CIPLE exam is administered by Camões — Instituto da Cooperação e da Língua at designated test centres in Portugal (and internationally). In Porto, exams are held at the Universidade do Porto language centre. Sessions run several times per year. Register at camonesteste.pt.
The exam covers reading, listening, and writing at A2 level. Most people who’ve been speaking Portuguese in daily life for 2–3 years pass comfortably. Consider a short intensive course in the 6–12 months before your application if you want to be certain of passing. See our Portuguese language guide for resources.
Criminal Record Requirements
You need a clean criminal record from two sources:
- Portuguese criminal record certificate (Certificado de Registo Criminal): obtainable online at registocriminal.justica.gov.pt or in person at IRN offices. Takes 1–3 days.
- Criminal record certificate from your home country: must be apostilled and, if not in Portuguese or English, officially translated. Processing time varies by country — UK DBS certificates take 2–8 weeks; US FBI background checks can take 2–3 months. Start this process well before you plan to submit your application.
A criminal record does not automatically disqualify you from citizenship — minor offences are assessed contextually. Serious offences may bar applications or require a longer waiting period. Discuss your specific situation with an immigration lawyer if you have any concerns.
Connection to Portugal
Beyond residency, language, and clean criminal record, applications must demonstrate a genuine connection to the Portuguese community (ligação efetiva à comunidade nacional). For families who have lived in Portugal for 5 years — with children in school, integrated into the community, speaking the language — this requirement is typically satisfied by the evidence of residency itself. Additional supporting evidence can include: school enrolment records for children, employment or business records in Portugal, tax returns filed in Portugal, and community involvement.
Where and How to Apply
Applications are submitted to the IRN (Instituto dos Registos e do Notariado) — the registry office. You can apply:
- Online via the Portal SIMPLEX at simplex.gov.pt — increasingly the preferred route, faster processing
- In person at an IRN service point (Conservatória do Registo Civil) — book an appointment online
- Via a Portuguese consulate if you are outside Portugal at the time of application — relevant if you have temporary absences
Most immigration lawyers recommend submitting through an IRN office in person or via a lawyer rather than online, at least for the first application — the in-person process allows for immediate clarification of any document queries.
Documents Required for the Application
- Valid passport
- Portuguese residence permit (current and valid)
- Evidence of 5 years of legal residency — residence permits covering the full period, AIMA registration receipts, renewal documents
- A2 Portuguese language certificate (CIPLE or equivalent)
- Portuguese criminal record certificate (recent — typically issued within 3 months of application)
- Criminal record certificate from home country (apostilled, recent)
- Birth certificate (apostilled, with certified translation if not in Portuguese or English)
- NIF
- Proof of current address
- Application form (provided at IRN or downloadable from irn.gov.pt)
- Payment of application fee (currently approximately €175 per applicant — verify current fee)
Processing Times: The Honest Reality
Processing times for Portuguese citizenship applications have been long — 12–24 months is the realistic range as of 2026, and some applications have taken longer. The Portuguese immigration system has been under significant pressure since 2022 with the increase in applications.
During processing, your existing residence permit remains valid and you remain a legal resident. Your existing passport continues to serve you. The wait is frustrating but your status is not in jeopardy while the application is pending.
Applications can be tracked online through the IRN system once submitted. If you hear nothing for over 18 months, follow up through an immigration lawyer who can chase the application on your behalf.
Children: The Simplified Path
Children have several routes to Portuguese citizenship that are faster or simpler than the adult naturalisation route:
Children born in Portugal to legal residents
A child born in Portugal to parents who have been legal residents for at least one year at the time of birth can apply for Portuguese citizenship. This has been one of the most significant changes in Portuguese nationality law in recent years. The application is made at the Conservatória do Registo Civil — typically done at birth registration. The child does not need to wait 5 years.
Children who complete primary school in Portugal
Children who complete at least one year of primary schooling in Portugal while their parents are legally resident may be eligible for citizenship through this route — the legal threshold varies and has been subject to reform. Discuss with an immigration lawyer for the current specific criteria.
Minor children of naturalised parents
When a parent obtains Portuguese citizenship, minor children can apply to acquire citizenship simultaneously or shortly after — through a declaration of acquisition rather than a full naturalisation application. This is faster and cheaper than a separate application.
Do You Need an Immigration Lawyer?
You can apply for citizenship without a lawyer — the process is navigable by a well-prepared applicant. In practice, most families use a lawyer for the citizenship application because:
- Document requirements are specific and a missing or incorrectly formatted document causes significant delays
- A lawyer can track the application and chase on your behalf
- Children’s applications, particularly those involving the birth-in-Portugal route or minor-of-naturalised-parent route, benefit from specialist guidance
- The cost (typically €500–€2,000 for a family application depending on complexity) is low relative to what’s at stake

The Timeline: Planning Backwards from Citizenship
| Milestone | When |
|---|---|
| Arrive in Portugal on D7/D8 visa | Year 0 |
| AIMA appointment — receive residence permit | Months 3–9 |
| First residence permit renewal | Year 2 |
| Start CIPLE language test preparation | Year 3–4 |
| Take CIPLE exam | Year 4 |
| Gather criminal record certificates (allow 3 months) | Year 4–5 |
| Submit citizenship application | Year 5 |
| Citizenship granted (estimated) | Year 6–7 |
The families who reach citizenship smoothest are those who start preparing — language, documents — in year 3 or 4 rather than scrambling in year 5.
Portuguese nationality law and application procedures change. This guide reflects the process as understood in 2026. Always verify current requirements at irn.gov.pt or with a licensed immigration specialist. Nothing here constitutes legal advice.
