Portuguese Citizenship

Portuguese citizenship grants all the rights of a European Union citizen, including freedom of movement, residence, and work in any country within the European Economic Area. For descendants of Portuguese nationals, spouses of Portuguese citizens, or long-term residents, Portuguese law offers various pathways to acquire nationality.

Ways to obtain Portuguese citizenship

By Descent (Assignment and Acquisition)

Portuguese law provides for different regimes depending on the degree of kinship:

• Children of Portuguese citizens citizenship granted automatically, regardless of country of birth
• Grandchildren of Portuguese can acquire citizenship by demonstrating effective ties to the Portuguese community (knowledge of the language, regular visits, active family ties)
• Great-grandchildren and later generations: can have access through the chain of acquisition (first the grandchild acquires, then the great-grandchild requests as a child of Portuguese)

By Marriage or Union de Facto

Spouses of Portuguese citizens can acquire nationality after 3 years of marriage (or recognized de facto union). The process requires a joint declaration and proof of the bond.

By Naturalization

Foreigners who have been legally resident in Portugal for at least 5 years and demonstrate sufficient command of Portuguese can apply for naturalization. The absence of serious convictions and effective ties to the community are also assessed.

Sephardic community

Descendants of Portuguese Sephardic Jews can apply for citizenship under a special regime by demonstrating historical ties to the Portuguese Sephardic community. Following legislative changes in 2024, new requirements have been introduced, including the demonstration of effective ties to Portugal.

Required documentation

The documentation varies according to the route chosen, but generally includes:

• Birth, marriage and death certificates (of the applicant and ascendants)
• Translated and apostilled documents (Hague Apostille)
• Proof of residence or link to Portugal
• Criminal record certificate
• For grandchildren: proof of effective ties with the Portuguese community

Our office advises on all the documentation, checks the completeness of the dossiers and accompanies the applications to the IRN and the Registry Offices.

Frequently Asked Questions about Portuguese Citizenship

Portuguese citizenship is granted to natural-born Portuguese citizens and to those who acquire it, such as: * **Children born in Portugal to foreign parents** if at least one parent was residing legally in Portugal for at least one year at the time of birth. * **Children born abroad to Portuguese parents** (father or mother) who are serving the Portuguese State. * **Children born abroad to Portuguese parents** if one of the parents is Portuguese and declares their wish for the child to be Portuguese and registers the birth in Portugal. * **Descendants of Portuguese Sephardic Jews** who demonstrate a tradition of belonging to a Sephardic community of Portuguese origin, based on a certificate from a Jewish community with ties to Portugal. * **Foreigners who have been legally residing in Portugal for at least five years** and meet certain requirements, such as knowledge of the Portuguese language. * **Spouses of Portuguese citizens** who have been married for at least three years and meet certain requirements. * **Individuals adopted by Portuguese citizens** after the adoption is finalized.

Children of Portuguese citizens have automatic entitlement. Grandchildren can acquire it by demonstrating effective ties with Portugal. Spouses of Portuguese nationals can apply for naturalization after 3 years of marriage. Residents for 5+ years can naturalize.

Can I have dual citizenship with Portugal?

Yes, Portugal allows dual citizenship without restrictions. This applies to Brazilians, Mozambicans, Angolans, Cape Verdeans and any other nationality. It is not necessary to renounce your original citizenship.

How long does the process take?

The timeframe varies depending on the type of application and the demand at the IRN. Applications for direct descendants (children) usually take between 6 and 12 months. Applications for grandchildren can take between 12 and 24 months, depending on proof of effective ties.

Do I need to speak Portuguese?

For naturalization (5 years of residency), yes — sufficient knowledge of the language is required. For citizenship by descent (children and grandchildren), fluency in Portuguese may be assessed as part of effective ties to the community, but it is not a mandatory formal requirement.
