Your options

3 Paths to Portuguese Citizenship.

Which route is right for you?

i

Ancestry-based route

Through Ancestry

If your parent or grandparent was Portuguese, you may already have the right to citizenship.

  • ·No residency required
  • ·No language test via a parent; the grandparent route is subject to the material requirements of the 2026 law
  • ·Apply from the US
  • ·We find Portuguese records
  • ·Filed via Portugal's Nationality Portal (lawyer access only)

Common for: Portuguese-Americans, descendants of Azorean immigrants, those with Portuguese heritage from New England, California, New Jersey, Hawaii.

ii

Spouse of Portuguese · 3+ years married

Through Marriage

If you're married to a Portuguese citizen for 3+ years, you can apply for citizenship.

  • ·No residency required
  • ·Ties to Portugal, including language and cultural integration, may be assessed
  • ·Apply from the US
  • ·De facto unions may qualify (judicial recognition required)

Requirements: Acquisition through marriage or a judicially recognised de facto union of more than three years with a Portuguese national is made by declaration and must not fall within the criminal, security and restrictive-measures grounds of article 6(1)(f) to (h). Where the marriage or union has lasted more than three but no more than six years, and the couple does not have common children of Portuguese nationality, evidence of effective ties to Portugal — including language and cultural integration — may remain relevant in opposition proceedings, which the Public Prosecutor may bring within two years of registration. Where the relationship has lasted more than six years, or the couple has common children of Portuguese nationality, opposition is limited to the applicable criminal, security and restrictive-measures grounds.

iii

Living in Portugal · 7 or 10 years

Through Residency

After the legal residence period — 7 or 10 years, depending on nationality — you can apply for naturalization.

  • ·7 or 10 years of residency required
  • ·Language, culture and civic requirements (2026 law)
  • ·Any legal visa qualifies
  • ·D7, D8, work permits count

Best for: Americans already living in Portugal on D7, D8, or other visas who want to become permanent EU citizens.

For US citizens

What Americans Need to Know.

Common questions from US citizens.

🇺🇸 Will I lose my US citizenship?

No. The United States allows dual citizenship. Becoming Portuguese does not affect your US passport or citizenship status. You will have two passports and can travel on either.

💰 What about US taxes?

Citizenship alone doesn't create tax obligations. As a US citizen, you already file taxes on worldwide income regardless of additional citizenships. Portuguese citizenship only creates Portuguese tax obligations if you become a Portuguese tax resident (living 183+ days in Portugal). The US-Portugal tax treaty prevents double taxation.

📍 Do I need to live in Portugal?

For a parent route, residence in Portugal is generally not required. A grandparent route has separate material requirements. Naturalisation by legal residence requires seven or ten years under the 2026 law. Any need for personal attendance must be checked for the procedure concerned.

🔐 Security clearances and government jobs?

Dual citizenship can affect certain security clearances or government positions. If this applies to you, we recommend consulting with your employer or legal counsel about your specific situation before proceeding.

FAQ

Frequently Asked Questions.

Yes. Both the United States and Portugal allow dual citizenship. You can become Portuguese while keeping your US passport. Neither country requires you to renounce the other.
The three main paths are: (1) Ancestry — if a parent or grandparent was Portuguese, (2) Marriage — if married to a Portuguese citizen for 3+ years, (3) Naturalisation — once the legal residence period is met: 7 or 10 years under the 2026 law.
The parent route does not generally require a language test. The grandparent route is subject to the material requirements introduced by the 2026 law, including sufficient knowledge of the Portuguese language and culture, history and national symbols, fundamental rights and duties, the solemn declaration and the applicable criminal and security conditions. Naturalisation by legal residence requires seven or ten years and the material requirements of article 6. Acquisition through marriage or a judicially recognised de facto union of more than three years with a Portuguese national is made by declaration and must not fall within the criminal, security and restrictive-measures grounds of article 6(1)(f) to (h). Where the marriage or union has lasted more than three but no more than six years, and the couple does not have common children of Portuguese nationality, evidence of effective ties to Portugal — including language and cultural integration — may remain relevant in opposition proceedings, which the Public Prosecutor may bring within two years of registration. Where the relationship has lasted more than six years, or the couple has common children of Portuguese nationality, opposition is limited to the applicable criminal, security and restrictive-measures grounds.
If you qualify through ancestry, much of the preparation and, depending on the parties' circumstances and the available procedure, parts of the formal process may be handled remotely or through legal representatives. Specific attendance or authentication requirements must be confirmed for each case. Naturalisation by legal residence requires living legally in Portugal for the qualifying period.
Legal fees are quoted in writing after the initial assessment, based on the scope and complexity of the work. Official fees and third-party costs are separate.

Yes. Portugal has not adopted any measure directed at US nationals: the visa routes remain open, the 2026 nationality reform changed timing rules for everyone rather than restricting any nationality, and Americans remain one of the largest groups of new residents in Portugal.
There is no shortcut: the route depends on your facts. Descent from a Portuguese parent or grandparent is typically the most expeditious where the records are consistent, because it does not depend on residence years. Marriage requires 3+ years of marriage or partnership with a Portuguese citizen. Naturalisation by residence requires 7 or 10 years under the 2026 law.
