Current Requirements at a Glance
Portuguese citizenship can be acquired through several distinct pathways, each with its own set of requirements and timelines. The most common routes include naturalization after a period of legal residence, marriage to a Portuguese national, birth on Portuguese territory, and descent from Portuguese ancestors.
The table below summarizes the key eligibility criteria for each pathway as of early 2026.
| Pathway | Key Requirement |
|---|---|
| Naturalization by residence | 5 years of legal residence in Portugal |
| Citizenship by marriage (living in Portugal) | 3 years of marriage to a Portuguese citizen |
| Citizenship by marriage (living abroad) | 6 years of marriage to a Portuguese citizen |
| Children born in Portugal | At least one parent with legal residence at time of birth |
| By descent (children/grandchildren) | Standard procedure through Portuguese ancestry |
Proposed Legislative Changes
A citizenship bill is currently under re-review in the Portuguese parliament following Constitutional Court objections. The proposed amendments would increase naturalization periods to 7 years for CPLP citizens and 10 years for all other third-country nationals. These changes have NOT yet taken effect. All applications submitted now are processed under the current rules outlined in this guide.
Naturalization by Residence (Article 6)
Naturalization through legal residence is the most common pathway for immigrants seeking Portuguese citizenship. After five years of continuous legal residence in Portugal, applicants who meet the language and integration requirements may submit their application.
Eligibility Requirements
- Legal residence in Portugal for a minimum of 5 consecutive years
- Portuguese language proficiency at A2 level, confirmed by an official certificate
- Demonstrated knowledge of Portuguese culture, history, and civic values (official test)
- Understanding of the rights and duties of Portuguese citizens (official test)
- Clean criminal record — no serious convictions in Portugal or countries of previous residence
Required Documents
- Birth certificate with apostille and certified Portuguese translation
- Valid passport (original and copy)
- Current Portuguese residence permit
- Criminal record certificates from country of birth, country of citizenship, and every country of residence after age 16
- Portuguese language certificate at A2 level (CAPLE or equivalent)
- Completed application form 1F
Costs
The official application fee is €250 for adult applicants and €200 for minors.
Citizenship by Marriage (Article 3)
Spouses of Portuguese citizens benefit from a simplified citizenship procedure. The required duration of marriage depends on whether the couple resides in Portugal or abroad.
| Condition | Required Duration |
|---|---|
| Couple living in Portugal | 3 years of marriage |
| Couple living abroad | 6 years of marriage |
Key Considerations
- The marriage must be registered in Portuguese civil records (Registo Civil)
- Applicants must demonstrate a genuine connection to Portuguese society — for example, through a joint child with Portuguese citizenship, evidence of cohabitation, or shared tax filings
- Civil partnerships (união de facto) are also recognized, but require prior court confirmation of the relationship
- No Portuguese language test is required for this pathway
Citizenship for Children Born in Portugal (Article 1)
Children born on Portuguese territory may acquire citizenship under specific conditions. This pathway is straightforward and does not involve application fees.
Requirements
- At least one parent must have held legal residence in Portugal at the time of the child's birth
- Parents must submit an official declaration requesting Portuguese citizenship for the child
- No application fee is charged for this pathway
Decisions on citizenship for children born in Portugal can sometimes be issued on the same day as the application, making this the fastest pathway.
Citizenship by Descent (Portuguese Ancestry)
Descendants of Portuguese citizens may claim citizenship through their family lineage. The process and requirements vary depending on the generational distance from the Portuguese ancestor.
Eligibility by Generation
- Children and grandchildren of Portuguese citizens — standard application procedure
- Great-grandchildren — must demonstrate a genuine connection to the Portuguese community, such as cultural ties, knowledge of the language, or regular visits to Portugal
- The Sephardic Jewish route has been closed to new applications
How to Apply for Portuguese Citizenship
There are several ways to submit a citizenship application. The most convenient method depends on your location and circumstances.
Online Through a Lawyer (Recommended)
The most convenient method — applying through the IRN platform with a licensed Portuguese lawyer or solicitor. No personal presence is required, documents are professionally reviewed, and you can apply from anywhere in the world.
In Person at a Registry Office
Applications can be submitted at any Conservatória do Registo Civil nationwide, or at IRN offices in major Portuguese cities. You will need to bring all original documents.
By Registered Mail
Documents can be sent by registered mail to: Conservatória dos Registos Centrais, Rua Rodrigo da Fonseca 198, 1099-003 Lisboa, Portugal.
Through a Portuguese Consulate
Portuguese consulates abroad accept citizenship applications from residents of their respective countries. Processing may take longer through this channel.
Processing Times
Processing times vary depending on the type of application, the quality of document preparation, and the current workload at the processing office. The estimates below are based on 2025–2026 data.
| Application Type | Estimated Processing Time |
|---|---|
| Naturalization (Article 6) | 12–18 months |
| By marriage (Article 3) | 12–18 months |
| Children born in Portugal (Article 1) | Same day to several weeks |
| By descent | 12–24 months |
The quality of your document preparation is the single most important factor in processing speed. Incomplete or improperly certified documents are the most common cause of delays.
Portuguese Language Exam (A2 Level)
Applicants for naturalization must demonstrate Portuguese language proficiency at the A2 level according to the Common European Framework of Reference (CEFR). This requirement does not apply to citizenship by marriage or descent.
Accepted Proof of Language Proficiency
- CAPLE certificate (Centro de Avaliação de Português Língua Estrangeira) — the most widely accepted option
- Diploma from a Portuguese educational institution
- Certificate from accredited Portuguese language courses
CAPLE Exam Structure
- Reading comprehension
- Written component
- Listening comprehension (often cited as the most challenging section)
- Speaking / oral interview
The passing score is 55 out of 100. Most candidates who have lived in Portugal for 2–3 years and used the language in daily life pass the exam successfully.
Dual Citizenship
Portuguese law fully permits dual (and multiple) citizenship. Neither the Nationality Law nor the Portuguese Nationality Regulation require applicants to renounce their existing citizenship when acquiring Portuguese nationality.
This means you can hold a Portuguese passport alongside your current passport without any legal conflict under Portuguese law.
Check Your Home Country's Rules
While Portugal allows dual citizenship, your country of origin may have restrictions. Before applying, verify whether your home country permits its citizens to hold a second nationality.
