Portuguese citizenship by descent, also known as citizenship by ancestry, allows those born outside Portugal to acquire citizenship through their familial ties to Portuguese citizens.

This pathway, based on the principle of jus sanguinis (right of blood), is available to individuals with Portuguese parents or grandparents, requiring proof of lineage and, in some cases, ties to the Portuguese community.

In this article, we’ll take a look at:

  • What Portuguese citizenship by descent is
  • Benefits of Portuguese citizenship by descent
  • Eligibility for Portuguese citizenship by descent
  • Required documents to apply for Portugal citizenship by descent
  • The application process

What is Portuguese citizenship by descent?

Portuguese nationality law allows individuals to become citizens of Portugal in two ways: Origin (through descent, passed from parent to child), or through acquisition (by marriage or naturalization).

This means that children of Portuguese parents or grandparents may apply for citizenship, provided they can prove their lineage or ancestral ties and meet documentation requirements.

Therefore, for individuals born outside Portugal, proving the lineage through birth and marriage certificates (apostilled and translated if necessary) is critical. You must have a direct ancestor, such as a parent or grandparent, who did not lose their nationality.

Benefits of Portuguese Citizenship by Descent

portugal citizenship by descent Obtaining Portuguese citizenship by descent offers many benefits, many of which stem from Portugal’s membership in the European Union (EU) and its favorable policies for dual citizens.

EU citizenship and mobility: Portuguese citizenship grants you full EU citizenship rights. This means you can live, work, and study in any of the 27 EU member states without the need for visas or additional work permits. It also provides freedom of movement across the Schengen Area, allowing visa-free travel to more than 180 countries worldwide.

High quality of life: You can enjoy the country’s exceptional quality of life, characterized by a mild climate, stunning landscapes, and rich cultural heritage. You gain access to affordable healthcare through Portugal’s national healthcare system, which is known for its comprehensive and high-quality services.

Portugal dual citizenship: Portugal allows dual citizenship, meaning you don’t have to renounce your current nationality as long as you home country allows dual citizenship, too. This flexibility allows you to retain the rights and privileges of your existing citizenship while enjoying the benefits of being a Portuguese citizen.

Generational continuity: Portuguese citizenship can be passed down to your descendants, ensuring that future generations can also benefit from the opportunities and rights associated with being a Portuguese and EU citizen. It also establishes a sense of belonging and connection.

Economic and financial advantages: Portuguese citizens can access the EU’s single market, which simplifies cross-border business and investment opportunities.

Eligibility Criteria and Requirements for Portugal Citizenship by Descent

The eligibility criteria for obtaining Portuguese citizenship by descent depend on proving a direct lineage to a Portuguese citizen. This route is available to individuals with Portuguese parents or grandparents, and the requirements will differ depending on your ancestor.

You have a Portuguese parent

portugal citizenship by descent As a Portuguese citizen, you can pass your citizenship to your children under several conditions. Portuguese nationality law allows for the transfer of citizenship to descendants, but the specific requirements depend on whether the child is born in Portugal or abroad and on the parents’ circumstances.

  • Automatic citizenship: If you are a Portuguese citizen and your child is born in Portugal, the child automatically acquires Portuguese citizenship at birth.
  • If your child is born outside of Portugal and at least one parent is Portuguese: If you are a Portuguese citizen and your child is born abroad, the child is entitled to Portuguese citizenship by descent. In this case, you will need to register the birth at the Portuguese civil registry or at the nearest Portuguese Consulate in the country where the child was born.

You have a Portuguese grandparent

If your grandparent(s) were Portuguese citizens, you’re also eligible to apply for Portuguese citizenship by descent. However, for eligibility, you would need to prove your lineage, just as you would through a parent. You will also need to:

  • Declare your intention to become a Portuguese citizen.
  • Demonstrate strong connections to the country, including a sufficient understanding of the Portuguese language.
  • Have a clean criminal record.
  • Register your birth in the Portuguese civil registry.

As a grandchild of a Portuguese citizen, you can apply for citizenship by descent at any age, as long as you fulfil the requirements to establish a connection to Portugal.

A recent proposal has also introduced the likelihood of extending the right to Portuguese nationality to great-grandchildren of Portuguese citizens as well, in cases of those born abroad.

You have Portuguese Sephardic ancestry

Individuals with Sephardic Jewish ancestry connected to Portugal can also apply for citizenship, requiring proof of lineage and connection to the Sephardic community.

The Portuguese nationality law recognizes the historical expulsion of Sephardic Jews from Portugal in 1496 and extends citizenship eligibility to their descendants. This initiative allows individuals with Sephardic Jewish ancestry to reconnect with their Portuguese heritage and obtain Portuguese citizenship.

In addition to proving their links to a Sephardic community of Portuguese origin, all applicants will be required to have legal residence in Portuguese territory for a period of at least three years, consecutive or interpolated.

Note: A proposal has been made to eliminate direct access to Portuguese nationality for Sephardic Jews. For the latest details, keep an eye on Global Citizen Solutions.

Here is a comprehensive list of the documents you will generally need when applying for Portuguese citizenship by descent: 

  • Official application form: Completed and signed by the applicant or their legal representative, and the signature needs to be notarized
  • Birth certificate: Must include the names of both of your parents

If the document is not in Portuguese, a translation by a translator recognized by the Portuguese Consulate is required.

How to Prove Effective Ties to Portugal

Establishing your connection to the Portuguese community is crucial for those looking to obtain Portuguese citizenship by descent. This can be accomplished by demonstrating a strong command of the Portuguese language. Another pathway is through cultural and community involvement, where you can participate in Portuguese cultural associations, show frequent visits to Portugal, or demonstrate engagement in Portuguese traditions.

Proficiency in the Portuguese language

While cultural involvement helps, language proficiency is the most important requirement for demonstrating effective ties. The following documents serve as acceptable evidence:

  • Certificate of proficiency obtained from a Portuguese private school or public school
  • Certificate of proficiency issued by the Portuguese Consulate during residency abroad, provided the Portuguese proficiency exam was taken through the Center of Evaluation of Portuguese Language (CIPLE) in Portugal or in other designated exam centers worldwide.
  • Certification of proficiency in Standard European Portuguese as a second language from any authorized Portuguese Evaluation Centre.
  • Diploma conferred by a recognized Portuguese public or private educational institution.
  • Submission of the school diploma suffices for graduates of public or private schools in Portuguese-speaking countries.

Portuguese speakers of former Portuguese territories, such as Brazil, don’t need to prove proficiency in the language. However, they still need to prove they have ties with the Portuguese community.

Step 2: Gather the required documents according to whether you are applying for citizenship through a parent or grandparent, complete the application form, and apply for Portuguese nationality at the Institute of Registries and Notaries of the National Center for Migrant Integration (CNAIM) in either Lisbon or Porto.

Step 3: The Portuguese authorities will assess and verify your documents and your lineage claim, and complete your criminal record background check. 

Step 4: Upon successful verification of your application, you will be granted Portuguese citizenship, and you will receive your Portuguese Citizenship Card as proof. You can then apply for a Portuguese passport.
