Overview
Other ways to acquire citizenship in Portugal include the following:
- Birth.
- Adoption.
- Marriage or partnership.
- Descent (Parents or grandparents).
- Sephardic Jewish ancestry.
- Belonging to former Portuguese territories.
Portugal Citizenship by Birth
Any person born in Portugal automatically receives citizenship if he/she has Portuguese parents or if at least one of his/her parents is a Portuguese national.
The Portuguese nationality law was amended on 11 November 2020. According to the amendment, children born to foreign parents will be eligible for Portuguese citizenship at birth if at least one has lived in Portugal legally for a year.
Portuguese Citizenship by Adoption
Any child who is adopted by a Portuguese citizen can apply for citizenship immediately if he/she is not up to 18 years of age. They must be legally adopted, however, and should show some connections to the Portuguese community.
Portuguese Citizenship by Marriage or Partnership
A foreign national who has been married or is in a de facto union for over 3 years with a Portuguese citizen is entitled to obtain Portuguese citizenship by marriage.
They must, however, show proof of the relationship (such as shared utility bills and shared rental or property deeds) and its duration as Portugal recognises marriages and long-term, stable relationships.
Applicants must also show proof of integration into the Portuguese community such as knowledge of the Portuguese language and ownership of property there.
Portuguese Citizenship by Descent (Parents or grandparents)
Foreign nationals who have a Portuguese grandparent or parent are eligible to apply for citizenship in Portugal at any age provided they can satisfy other requirements such as some level of knowledge of the Portuguese language.
To prove that the applicant has a Portuguese parent or grandparent, he/she would have to produce documents such as a birth certificate and marriage certificate.
The Portuguese ascendant of the applicant cannot be above the second degree (grandparent), otherwise, he/she becomes ineligible to apply for citizenship.

Portuguese Citizenship by Sephardic Jewish ancestry
The Portuguese nationality law offers citizenship to Sephardic Jews and those with Sephardic Jewish heritage. These categories of people have a history of being expelled from the Iberian Peninsula hundreds of years ago. Therefore, the Portuguese government is offering them citizenship to correct this moral wrong.
Persons who desire to obtain Portuguese citizenship through this route must be at least 18 years of age and not be found to have committed a crime punishable by three years (or above) of imprisonment under Portuguese law.
To apply for citizenship in Portugal via this route, the applicant must provide the following documents:
- A birth registration certificate.
- A passport copy.
- A criminal record certificate issued by the relevant Portuguese authorities, the country of residence, or the country of origin.
- A Portuguese Jewish community certificate proving Sephardic Jewish lineage of Portuguese origin. This can be through surname, language, genealogy, or family memory.
Portuguese Citizenship by belonging to Former Portuguese Territories
Persons who are citizens of former Portuguese colonies can apply for Portuguese citizenship because Portugal maintains a special relationship with them since post-colonization.
These colonies include Guinea-Bissau, East Timor, Macau, Brazil, Cape Verde, Angola, Portuguese India, São Tomé and Principe, and Mozambique.
