Obtaining Portuguese Citizenship Through Your Parents

If one of your parents is a Portuguese citizen, you have one of the strongest possible claims to Portuguese citizenship. Under Portuguese nationality law, this is known as citizenship by attribution (atribuição da nacionalidade) — meaning you are treated as Portuguese by birth once the process is completed, rather than having to “earn” citizenship through residency or other conditions.

This is the most direct route to a Portuguese passport and, with it, the right to live, work, and travel freely across all European Union member states.

If your connection is through a grandparent rather than a parent, that route is also available but it is slightly more challenging as it requires you to show an A2 knowledge of Portuguese.

Do You Qualify?

You are likely eligible if at least one of your parents is a Portuguese citizen by birth. This applies even if:

• You were born in the United States, Canada, or anywhere else outside Portugal
• You have never lived in or visited Portugal
• Your parent emigrated decades ago and never returned
• Your parent has since passed away

One important distinction: Portuguese citizenship acquired through naturalization cannot be passed down. Only citizenship held by birth (nacionalidade originária) can be inherited. If your parent became Portuguese through naturalization rather than by being born Portuguese, this route is not available to you — but the grandparent route may still be worth exploring.

If you are unsure of your parent’s citizenship status, this is one of the first things worth clarifying.

Why This Is the Simplest Route

Compared to other paths to Portuguese citizenship, applying through a parent does not require you to:

• Pass a Portuguese language exam
• Demonstrate ties to the Portuguese community
• Have ever lived in Portugal

Your direct parentage is the tie. The law recognizes that.

Common Questions

Does my parent need to be alive? No. You can apply based on a deceased parent’s citizenship.

Does my parent’s marriage need to be registered in Portugal? In some cases, yes — particularly if names or records need to be matched across documents. This is something to check early.

What if my parent changed their surname? This can complicate record-matching but is not a barrier. Different civil registries may require different supporting documents to establish the link.

Can citizenship through a naturalized parent be passed down? No. Only citizenship held by birth can be inherited, not citizenship acquired through naturalization.

How Long Does It Take?

Processing times vary depending on the consulate or registry handling your application, but backlogs are significant across the board. You should expect anywhere from one to four years from submission to receiving your citizenship certificate and passport (passaporte português).

What If You Want to Move Sooner?

A citizenship application does not prevent you from pursuing other routes to living in Portugal or the EU in the meantime. Portugal offers several residency visas that many applicants use while their citizenship application is in progress, including:

• The D7 Visa — for those with regular passive income such as a pension, rental income, or Social Security
• The Digital Nomad Visa — for remote workers and freelancers
• The Golden Visa (Visto Gold) — for those with qualifying investments

A residency application can be approved in as little as three to twelve months. Running both processes in parallel is entirely possible and a practical option if moving to Europe is your goal rather than just the passport.

Getting It Right Matters

Knowing exactly which documents are required, obtaining records from Portuguese archives, getting those documents correctly apostilled and translated, and navigating consulate correspondence that can be slow to respond — this is where most people run into problems.

Errors or missing documentation at the submission stage can mean rejections or significant additional delays in an already long process.

Many applicants find that working with legal assistance gives them confidence that the application is being put together correctly from the start.
