Portugal – Citizenship

Who is eligible to apply for citizenship in Portugal?

The rules governing Portuguese citizenship are contained in the Portuguese Nationality Law (Law No. 37/81, as amended), which operates alongside the Civil Code and is administered by the Central Registry Office. Several separate routes to citizenship exist, each carrying its own set of conditions — identifying which pathway fits your personal circumstances is an essential first step before commencing the process.

Naturalisation after residency

If you cannot claim citizenship through birth or ancestry under Portugal’s Nationality Law, naturalisation may be available to you. To qualify via this route, you must demonstrate that you have been residing in Portugal lawfully and without significant interruption for a minimum of five years prior to your application, and you must show an adequate command of the Portuguese language and familiarity with Portuguese culture. This five-year threshold is broadly comparable to the requirements found in countries such as Canada and France, though it is meaningfully shorter than the ten-year periods demanded by Germany and Switzerland. It is important to note that the 2025 amendments to the Portuguese Nationality Law have not yet come into force — the Constitutional Court struck down several of their provisions, requiring Parliament to revise the text before the President can promulgate and publish it. Until that process concludes, the existing five-year rule continues to apply.

“Lawful residence” means holding a valid Portuguese residence permit (Título de Residência). Time spent in Portugal on tourist visas or under visa-waiver arrangements does not count toward the five-year period. Holders of D-visas — including the D7 passive income visa, the D2 entrepreneur visa, and various work visas — all qualify, as does the Golden Visa investment permit.

Citizenship by descent

No residency requirement applies to citizenship acquired through ancestry. You may be eligible through a grandparent who retained their Portuguese nationality, provided you have either lived in Portugal for at least three years or can demonstrate a substantive connection to the Portuguese community, which ordinarily includes an ability to speak the language. Proposed 2025 reforms would confine this route to third-generation descendants who can establish a genuine link, so those relying on grandparental ancestry should follow legislative developments closely.

Citizenship by marriage or civil partnership

Citizenship may be granted following at least three years of marriage to, or civil union with, a Portuguese national. There is no specific prior residency requirement, but applicants must show a genuine connection to the Portuguese community, which typically includes demonstrating proficiency in Portuguese. The three-year marriage threshold resembles the spousal naturalisation route found in Australia — which also involves a two-year permanent residency requirement or a three-year de facto partnership — but it differs from many comparable systems in that physical residence in Portugal is not an absolute precondition.

Citizenship by investment (Golden Visa)

After five years, investors who hold a Golden Visa may become eligible for Portuguese citizenship and an EU passport, opening up extensive visa-free travel and the right to live and work throughout the European Union. The Golden Visa requires only a minimum of seven days of physical presence per year during the qualifying period, making it one of the most flexible investment-based routes available in Europe, where most other countries demand considerably longer stays. Following the removal of the residential property option in 2023, the programme now centres on alternative investment funds approved under the Portugal Golden Visa framework. The required investment stands at €500,000 in eligible funds.

Disqualifying conditions

Applicants must be free of serious criminal convictions. Under Portuguese law, a serious conviction is generally understood as one resulting in a custodial sentence of three years or more. Criminal record certificates from Portugal and from your country of origin — as well as any other countries in which you have resided — are required as part of the application. Those unable to prove continuity of lawful residence, or who have submitted falsified documentation, will also be ineligible.

What are the steps involved in applying for citizenship in Portugal?

The application is a rigorous administrative procedure managed by the Institute of Registries and Notaries (IRN — Instituto dos Registos e do Notariado). Meeting the eligibility criteria is necessary but not sufficient; applicants must also follow each procedural step with precision. The fee for a Portuguese nationality application is €250, payable by debit card at the point of submission. Always consult the IRN official website for the most up-to-date fee, as the figure is subject to revision.

1. Confirm your eligibility and assemble your documents. Begin by gathering all required materials, including proof of identity, documentation evidencing your residency, and certificates of language proficiency. Every document must be current, accurate, and — where required — translated into Portuguese and formally certified. You will also need criminal record certificates from Portugal and from every country in which you have lived since the age of 16.
2. Pass the language proficiency test. The standard approach is to sit the CIPLE (Certificado Inicial de Português Língua Estrangeira) examination and obtain the official certificate. This test assesses Portuguese at the A2 level and is administered by CAPLE (Centro de Avaliação de Português Língua Estrangeira) and its accredited centres worldwide. The CIPLE certificate is widely accepted by the IRN as evidence of language ability.
3. Complete the application form. The Modelo 6.1 application form can be downloaded from the IRN website. If submitting by post or in person, it must be printed double-sided and completed in black ink using block capital letters. If you are working with an immigration lawyer, they will fill in the form on your behalf based on the documents you supply.
4. Submit the application. Naturalisation applications may be lodged at an IRN office, at a CNAIM (National Support Centres for Migrant Integration), at a citizen shop, or — if you are outside Portugal — through a Portuguese embassy or consulate. Many applicants opt to use a licensed immigration lawyer, who can submit electronically and monitor progress on their behalf.
5. Pay the application fee. A fee of €250 is payable at the time of submission (as of 2024–2025). Verify the current amount on the IRN’s official website before proceeding.
6. Verification and background checks. The process involves several stages. The Registry Office and IRN system accept and log the application, authorities verify all submitted documents against legal standards, and relevant bodies are consulted to confirm the applicant’s criminal record. Once all conditions have been confirmed, a decision on citizenship is issued.
7. Monitor your application online. Applicants can follow the progress of their case online using a query code issued by the Central Registry Office in Lisbon. This service is free of charge and does not require a visit to the IRN in person.
8. Receive confirmation and register as a citizen. Successful applicants are formally recorded as Portuguese nationals in the Civil Registry. You may then apply for your Portuguese passport and citizen card (Cartão de Cidadão).
9. Apply for your passport. Once citizenship has been confirmed, passport applications can be submitted at IRN offices, at passport shops located in Lisbon and Porto airports, or at your local Portuguese embassy or consulate.

Current processing times run to approximately 18–24 months from the point of submission (as of 2025), though this can vary depending on application volumes. Consult the IRN website for the latest estimates.

What tests, interviews, or ceremonies are required as part of the citizenship process?

Portugal does not require a general citizenship test of the kind used in the United States; however, applicants must pass a language proficiency examination — the CIPLE (Certificado Inicial de Português Língua Estrangeira) — at A2 level. The A2 threshold on the Common European Framework of Reference (CEFR) reflects a basic conversational competence, sufficient for handling everyday interactions. By way of comparison, the UK Life in the UK test demands a higher combined standard of language and civic knowledge, and Australia’s citizenship test is a formal written assessment of civic matters.

The examination is divided into reading and writing (45%), oral comprehension (30%), and oral expression (25%). It is offered several times throughout the year at accredited testing centres in Portugal and internationally. Many candidates favour this route because it is straightforward, broadly recognised by the IRN, and relatively affordable.

In certain circumstances the law permits alternative evidence in place of the CIPLE certificate — for example, school diplomas confirming completion of basic or secondary education in Portugal or in another officially recognised Portuguese-speaking country (CPLP), or certificates from specific Portuguese language programmes — but only where the institution concerned is formally recognised by the Portuguese government.

The revised nationality law currently under parliamentary review would introduce an additional civics element: alongside demonstrating A2-level Portuguese, applicants would be required to pass a test covering Portuguese culture, history, and fundamental rights. This requirement has not yet entered into force, but prospective applicants should keep a close watch on developments.

The Civil Registry Office or AIMA authorities may also conduct an interview or screening to verify the authenticity of submitted documents and to assess the applicant’s ties to the Portuguese community — which may involve presenting evidence of relationships or integration. Unlike the United States, where a formal public oath of allegiance is a compulsory element of naturalisation, Portugal currently has no equivalent public swearing-in ceremony.

What are the benefits of citizenship in Portugal?

Acquiring Portuguese citizenship confers a wide range of rights and tangible advantages that extend considerably beyond what is available to long-term or permanent residents. A residence permit allows you to live in the country, but it carries conditions: periodic renewals, minimum stay obligations, and limited political rights. Citizenship, by contrast, is permanent. You can be absent from Portugal for many years and still return with the full protection of the law.

Portuguese passport holders enjoy visa-free or visa-on-arrival access to more than 190 countries, placing it consistently among the world’s most powerful travel documents. As a Portuguese national, you can move freely throughout all 27 EU and Schengen member states without additional visa requirements, facilitating leisure travel, business trips, and short-term stays across the continent.

The right to live and work throughout the EU is one of the most consequential practical benefits of Portuguese citizenship for non-EU nationals. As a citizen, you can establish yourself in any EU or EEA country without needing additional permits or authorisations — effectively opening the entire European labour market to you.

Holding Portuguese citizenship also means being entitled to vote in national elections, obtaining an EU passport, and ending the cycle of residency permit renewals and the uncertainty that can accompany changes in immigration policy. While permanent residency and citizenship share certain features, Portuguese citizenship additionally carries the right to participate in all elections and to hold a passport and citizen card.

Portuguese citizens enjoy full access to the national health service (SNS), which is recognised for its quality and affordability. Access to higher education is equally favourable: citizens benefit from lower tuition fees at Portuguese universities and from EU fee rates when studying elsewhere in Europe. Unlike residency-based entitlements, citizenship secures these benefits on a permanent footing.

One of the most enduring advantages of Portuguese citizenship is its transmissibility to future generations. Children born after naturalisation automatically acquire citizenship, allowing families to build lasting European foundations that extend across generations.

Once naturalised, the Portuguese Constitution places the new citizen on an equal constitutional footing with those born Portuguese — meaning access to public sector and civil service roles that may be reserved for citizens, as well as the right to hold a Portuguese diplomatic passport when travelling in an official capacity.

Does Portugal allow dual citizenship, or will you have to renounce your existing nationality?

Portugal permits dual and even multiple citizenship. Portuguese nationality law contains no requirement to give up your original nationality upon becoming Portuguese. The country imposes no restrictions on individuals who hold another citizenship alongside their Portuguese one, and this permissive approach is embedded in statute.

The Portuguese Nationality Law expressly allows dual citizenship, meaning foreign nationals can acquire Portuguese nationality without relinquishing the citizenship of their country of origin. Similarly, a Portuguese national who acquires a foreign citizenship does so without forfeiting their Portuguese status.

The key question, therefore, is not whether Portugal will permit you to hold two nationalities, but whether your current home country will allow you to do so. Portugal’s own position is unambiguous — but countries differ substantially in their approach. Nations such as the United Kingdom and Canada permit dual citizenship without restriction, while others, including China and Singapore, prohibit it entirely. You should consult the official immigration, foreign affairs, or interior ministry of your home country before proceeding, as the consequences of acquiring a second nationality can vary considerably depending on your situation.

Dual citizens are subject to the laws of both countries and may face tax obligations in each, depending on the relevant regulations. It is strongly advisable to obtain independent legal and tax advice covering both jurisdictions before submitting your application.

Naturalised citizens who are convicted of serious offences resulting in sentences of five years or more may lose their Portuguese citizenship within ten years of naturalisation, subject to judicial discretion and the principle of proportionality — this represents one of the very few circumstances in which Portuguese citizenship, once granted, can be taken away.

How long does it typically take to become a citizen of Portugal?

The overall journey from first arriving in Portugal to holding a Portuguese passport encompasses several distinct stages, and the total duration will depend on your chosen route, how quickly you satisfy the eligibility criteria, and the prevailing processing times at the IRN.

Under the legislation currently in force (as of early 2026), Portugal’s longstanding five-year pathway from legal residence to naturalisation has been the foundation of many foreign residents’ long-term planning. With effect from 1 April 2024, the date on which an applicant’s temporary legal residence permit commences is taken into account when calculating the qualifying period for naturalisation applications. This means the clock begins running from the start date of your D-visa residency, which in practice shortens the wait for many applicants compared with the position under earlier rules.

The legislative framework is, however, in a state of flux. On 28 October 2025, Portugal’s parliament approved significant amendments to the Nationality Law, including an increase in the residency requirement from 5 to 10 years for most applicants, and 7 years for CPLP nationals and EU citizens. These changes have not yet taken effect. Following parliamentary approval in October 2025, the law was referred to the Constitutional Court before the President could sign it. On 15 December 2025, the Court declared four provisions unconstitutional, preventing the law from proceeding in its current form. Parliament must now revise or remove the offending provisions before the President can sign the final text into law.

A realistic overview of the timeline under the current rules is set out below:

Should the proposed reforms ultimately enter into force in a revised form, the majority of applicants would need to allow at least ten years of residency before applying, making the overall realistic timeline substantially longer. Always check the most current processing times directly with the IRN, as these figures fluctuate with the volume of applications received.

What are the main reasons an application for citizenship in Portugal might be refused?

A clear understanding of the most common grounds for refusal will help you put together a stronger application from the start. The IRN applies the Portuguese Nationality Law strictly, and incomplete or defective submissions are among the most frequent causes of delays and rejections.

• Criminal record. Applicants must have no serious criminal convictions. A serious conviction is generally defined as one resulting in a custodial sentence of three years or more under Portuguese law. Even offences committed outside Portugal can give grounds for refusal if they meet this threshold.
• Insufficient or interrupted residency. The qualifying period is calculated from the date of entry with a Portuguese D-level residence visa to the date of submission to the IRN. Residing in Portugal in a physical sense is not enough — you must have maintained the correct legal status throughout, something the IRN will scrutinise carefully.
• Failure to satisfy the language requirement. Applicants must demonstrate a working knowledge of Portuguese at A2 level. For those who have not devoted sufficient effort to learning the language during their time in Portugal, this requirement can present a genuine obstacle.
• Incomplete or defective documentation. Missing apostilles are a particularly common cause of rejection. Documents that have not been correctly translated, notarised, or authenticated will typically prompt a request for supplementary information or may result in outright refusal.
• Inability to demonstrate genuine ties. Applicants who cannot show a genuine connection to the Portuguese community — a requirement that is especially relevant for citizenship by descent or by marriage — may find their applications refused on this basis.
• Threats to national security or public order. The Nationality Law provides for refusal where granting citizenship would constitute a threat to national security or public order.

If your application is refused, you have the right to challenge the decision through the Portuguese administrative court system. Working with a qualified immigration lawyer in Portugal is strongly recommended if your situation is complex, if documentation must be sourced from several different countries, or if you have received a refusal and wish to mount an appeal.

Where can you find reliable, up-to-date information about citizenship in Portugal?

Portugal’s citizenship rules have undergone significant change in recent years and remain subject to active legislative reform. The only sources that can be relied upon for accurate, current information on requirements, fees, and processing times are official government bodies and their websites. Blog posts, social media commentary, and third-party aggregator sites should not be used for specific legal requirements, as they may be out of date or incomplete.

• Instituto dos Registos e do Notariado (IRN): The principal official authority for citizenship applications. The IRN website hosts application forms, fee schedules, and guidance documents. Visit: www.irn.mj.pt
• Agência para a Integração, Migrações e Asilo (AIMA): AIMA now holds responsibility for immigration, asylum, and border control, having taken over from the former SEF (Serviço de Estrangeiros e Fronteiras). AIMA handles the verification of residency permits as part of the citizenship process.
• Official Portuguese Government Portal: The central public administration portal provides guidance on acquiring Portuguese nationality. Visit: www.gov.pt
• Portuguese Consulates and Embassies: If you are applying from outside Portugal, your nearest Portuguese consulate is the appropriate point of contact. The procedures for applying for nationality may vary depending on where you were born, how long you have lived in Portugal, the nationality of your family members, and your relationship with the Portuguese community.
• Ministry of Justice (Ministério da Justiça): The IRN operates under the Ministry of Justice, which publishes the official text of the Nationality Law and any amendments to it. Visit: justica.gov.pt

Given the pace and extent of recent legislative change to Portugal’s Nationality Law, checking official sources immediately before beginning the application process is especially important. If your circumstances are at all complex — for instance, if you are pursuing citizenship through multiple generations of ancestry, or if there are gaps in your residency history — seek advice from a qualified Portuguese immigration lawyer before submitting your application.

Frequently asked questions about citizenship in Portugal

Do children born in Portugal automatically acquire Portuguese citizenship?

Families should be aware of how pending reforms may affect children born in Portugal. Under the proposed changes, a child would only receive citizenship at birth if at least one parent had been a legal resident for a minimum of three years before the birth. Under the legislation currently in force, a child born in Portugal to foreign parents may acquire citizenship if at least one parent has been legally resident for the required minimum period. As this area remains subject to the pending legislative reforms, confirm the current position on the IRN website or with a legal professional before assuming any automatic entitlement.

Can Portuguese citizenship be lost or revoked?

Naturalised citizens convicted of serious offences carrying sentences of five years or more may lose their citizenship within ten years of naturalisation, subject to judicial discretion and the principle of proportionality. Citizenship acquired by birth or descent is far more difficult to lose. Voluntarily renouncing Portuguese citizenship is also possible by means of a formal declaration to the relevant civil registry authority, though this step is irreversible.

What happens to my citizenship application if I move abroad during the process?

Once you have lodged your application with the IRN, you are not obliged to remain in Portugal while it is being considered. However, you must hold valid legal residency both at the time of submission and at the point when the IRN verifies your eligibility. Should your residency permit expire or not be renewed during the processing period, complications are likely to arise. It is essential to keep all residency documentation current throughout the entire process.

Does my home country’s position on dual nationality affect my Portuguese citizenship application?

Portugal will not itself prevent you from holding dual nationality. The relevant question is whether your home country will allow it. Countries such as the United Kingdom and Canada permit dual citizenship without restriction, while others including China and Singapore prohibit it entirely. Your eligibility to retain your existing nationality will therefore depend on the laws of your country of origin. Always consult the relevant official authority — immigration, foreign affairs, or interior ministry — in your home country before proceeding.

Can I apply for citizenship through a great-grandparent’s Portuguese nationality?

Under the current Nationality Law, citizenship by descent is generally available through a Portuguese parent or grandparent. Claims through a great-grandparent have historically required demonstrating a particularly strong and genuine link to the Portuguese community. Under the proposed 2025 reforms, ancestry-based nationality would be restricted to third-generation descendants who can furnish evidence of a genuine connection. As the law remains under revision, establish your current eligibility with the IRN or a qualified immigration lawyer before pursuing this route.

Are there any age-related exemptions from the language test?

Applicants are generally required to demonstrate a basic knowledge of Portuguese, typically by passing the CIPLE examination at A2 level, which covers reading, writing, listening, and speaking. Certain exemptions exist for older applicants and for those educated in Portuguese-language institutions. The precise exemptions are set out in the Nationality Law and its implementing regulations — consult the IRN or a legal professional if you believe an exemption might apply to your situation.

Can I apply for Portuguese citizenship while living outside Portugal?

Naturalisation applications may be submitted through a Portuguese embassy or consulate if you are based abroad. However, you must have completed the required qualifying residency period inside Portugal before applying — having a connection to Portugal from abroad, without having actually lived there for the requisite period, does not fulfil the conditions for naturalisation, though the position may differ for descent or marriage routes.

Is there a Sephardic Jewish ancestry route to Portuguese citizenship?

Portugal has historically offered a dedicated citizenship route for descendants of Sephardic Jews who were expelled from Portugal in the fifteenth century. The 2025 reform proposals would abolish this pathway. However, because the reform law has not yet entered into force following the Constitutional Court’s review, the current legal status of this route should be confirmed directly with the IRN or a qualified Portuguese immigration lawyer.

Will proposed residency reforms apply retroactively to people already living in Portugal?

The proposed ten-year residency requirement would not apply automatically on a retroactive basis. The Constitutional Court held that pending citizenship applications cannot be reassessed automatically under the extended timeline. If you are already resident in Portugal and approaching the existing five-year threshold, seeking immediate legal advice is worthwhile to clarify your position under the current law and any transitional provisions that may be applicable.

What is the difference between permanent residency and citizenship in Portugal?

Permanent residency entitles holders to live and work in Portugal without the need to renew temporary permits every two years. It does not, however, confer voting rights or an EU passport, though it does allow visa-free movement within the 29-country Schengen area for stays of up to 90 days in any 180-day period. Citizenship goes further: it carries full voting rights in all elections, entitlement to a Portuguese passport and citizen card, and the right to live and work anywhere in the EU. Citizenship is also permanent and cannot be lost through inactivity, whereas residency status must be actively maintained and renewed.

Can I track the progress of my citizenship application?

Applicants who have already submitted a Portuguese nationality application can monitor the status of their case online using the query code provided at the time of submission by the Central Registry Office. For a more detailed review of your file, you should contact the registry where you lodged your application or the Central Registry directly. The online tracking service is free and available at any time, without the need to visit an IRN office in person.
