Portugal Dual Citizenship is becoming one of the most sought-after options for Americans looking to expand their opportunities abroad. 

In 2025, gaining Portuguese nationality offers U.S. citizens the freedom to live, work, and travel across the EU, while keeping their American passport. 

With new law changes on the horizon, this guide walks you through the latest requirements, available pathways, and a clear roadmap to securing dual citizenship in Portugal.

📢 Portugal Citizenship Law Update 2026

On May 18, 2026, Portugal officially published the new Nationality Law in the Diário da República, confirming the latest legislative changes affecting Portuguese nationality procedures and eligibility rules. The new law entered into force on May 19, 2026.

Key changes:

  • Residency requirement: 10 consecutive years, or seven years if you are a citizen of the Community of Portuguese Language Countries
  • Start date: counted from the first residence permit issuance
  • No transition: previous 5-year rule not protected
  • Waiting time: no longer counts

The Government will have 90 days to issue implementing regulations, mainly to clarify procedures.

Does Portugal Allow Dual Citizenship?

Yes. Portugal allows dual citizenship, meaning you can become a Portuguese citizen without renouncing your original nationality, as long as your home country also permits dual nationality.

Once approved, you hold the same rights as any Portuguese citizen, including:

  • living and working anywhere in the European Union
  • visa-free travel to over 185 countries
  • access to Portuguese healthcare and education.

How to Get Dual Citizenship in Portugal

There are several legal pathways to obtain Portuguese citizenship while keeping your original nationality. Portugal allows dual citizenship, meaning you can become a Portuguese citizen without renouncing your existing passport if your home country also permits dual nationality.

The most common routes include the following:

1. Citizenship by descent

Individuals with Portuguese ancestry may be eligible for citizenship through their parents or grandparents.

For example, if one of your parents is Portuguese, you can usually apply for citizenship directly. If you have a Portuguese grandparent, you may also qualify, provided you demonstrate a connection to the Portuguese community.

This pathway is often the fastest way to obtain Portuguese citizenship.

2. Citizenship by naturalization

Foreign nationals can apply for Portuguese citizenship after 10 years of legal residency in Portugal, or seven years if you are a citizen of a CPLP country

Applicants must typically demonstrate:

  • basic knowledge of the Portuguese language (A2 level)
  • a clean criminal record
  • proof of legal residency during the qualifying period

For example, someone living in Portugal with a D7 visa or work visa can apply for citizenship after completing five years of residence.

3. Citizenship by marriage

Individuals married to or in a long-term relationship with a Portuguese citizen may apply for citizenship after three years of marriage or de facto union.

Applicants may need to show evidence of a genuine connection to Portugal, such as language knowledge, residence in the country, or ties to the Portuguese community.

4. Citizenship through residency programs

Many foreign nationals first obtain Portuguese residency through visa programs and later apply for citizenship.

Common residency routes include:

After maintaining legal residency for five years, applicants may become eligible to apply for Portuguese citizenship and obtain a Portuguese passport.

For example, an investor using the Golden Visa program can maintain minimal physical presence in Portugal while still qualifying for citizenship after the required residency period.

Can US Citizens Have Dual Citizenship with Portugal?

The United States does allow dual citizenship, even though it doesn’t openly encourage it. US law doesn’t require citizens to choose one nationality over another, so you can legally hold a US passport alongside a second one — like Portugal’s.

However, the US government expects dual citizens to follow US laws and obligations, such as filing taxes (even if you live abroad) and, for men, registering for Selective Service if applicable. You won’t lose your US citizenship just by becoming a citizen of another country, unless you voluntarily intend to give it up.

For example:

  • An American moving to Portugal with a D7 visa could apply for citizenship after five years.
  • A US investor using the Golden Visa program can also apply for citizenship after maintaining residency for the required period.

Benefits of Portugal Dual Citizenship

Holding dual citizenship with Portugal offers significant advantages, particularly for U.S. citizens seeking greater mobility, lifestyle flexibility, and long-term security.

1. Freedom to Live Anywhere in the EU

As a Portuguese citizen, you automatically become a European Union citizen. This allows you to live, work, study, or retire in any of the 27 EU countries without needing visas or work permits. For example, you could live in Portugal while working in Germany, studying in France, or retiring in Spain.

2. Visa-Free Global Travel

A Portuguese passport provides visa-free or visa-on-arrival access to over 185 countries, including the UK, Canada, Japan, and most of Europe. This makes it one of the most powerful passports in the world, offering greater flexibility for travel, business, or international living.

3. Access to Public Healthcare and Education

Portuguese citizens have full access to Portugal’s public healthcare system and education network. Healthcare costs are generally low, and public universities offer high-quality education at relatively affordable tuition fees.

4. Family Opportunities

Dual citizenship can also benefit your family. In many cases, children can inherit Portuguese citizenship, giving them EU rights from birth. Citizens can also sponsor family members to live in Portugal through family reunification pathways.

5. Greater Security and Flexibility

Holding two citizenships provides greater personal and financial flexibility. It allows you to live, work, and invest across multiple jurisdictions while maintaining legal rights in both countries — offering an additional layer of security in an increasingly uncertain global environment.

Does Dual Citizenship Mean Paying Taxes in Portugal?

Not necessarily. Portugal taxes individuals based on tax residency, not citizenship.

You generally become a Portuguese tax resident if you:

  • spend more than 183 days in Portugal, or
  • maintain a permanent home in the country.

How to Apply for Portuguese Dual Citizenship: Step-by-Step

Getting dual citizenship in Portugal is a structured process, but with the right guidance, it’s very achievable. Here’s a step-by-step overview on how to get dual citizenship in Portugal:

1. Determine Your Eligibility

You may be eligible through naturalization, marriage, descent (Portuguese parents or grandparents), or Sephardic Jewish ancestry. For naturalization, you typically need at least 5 years of legal residence in Portugal. Time under certain visas, like the D7 or Golden Visa, can count toward this.

2. Gather Required Documents

  • Valid passport
  • Portuguese residence permit
  • Criminal background checks (from Portugal and your home country)
  • Proof of language proficiency (A2 level in Portuguese)
  • Birth certificate and other supporting documents depending on your case

3. Submit Your Application

Applications are submitted to IRN (Instituto dos Registos e Notariado) or through a Portuguese consulate if you’re abroad.

4. Wait for Approval

Processing times can vary but generally range from 6 to 29 months, depending on your citizenship route and the complexity of your case.

5. Obtain Your Citizenship Certificate

Once approved, you’ll receive your Portuguese citizenship certificate and we can then apply for the Portuguese ID Card and passport.

What Our Clients Say

Tim Evans
Tim EvansUSA
We began working with Portugal Residency Advisors (PRA) in April 2024 to consider residency in Portugal. Pedro Branco and Beatriz Garcia provided critical incite and information in helping us decide how best to apply for the Portugal Golden Visa Program. The most wonderful thing was that their advice was completely independent and they were not trying to sell us any investment scheme that they would benefit PRA. They provided professional advice and let us decide what worked best for us. We completed the process in less than two months. I highly recommend that you talk with them regardless of who you have talked with already.

My experience with Portugal Residency Advisors has been exceptionally good. Pedro Branco (client manager) provided me with clearly set out details of their services and costs and timeline. Right from the start, Beatriz Garcia (immigration lawyer) has promptly set out clearly what steps I needed to take for my visa application. She was always helpful and supportive (when I was feeling stressed by the process) and guided me through it with patience and a quick response. Portugal Residency Advisors took me through a complicated and detailed process efficiently and clearly, and I am sure that it would have taken me much longer, and with much more stress, without them.

I recommend to Beatriz Garcia and Portugal Residency Advisors completely. They helped us with our immigration meetings scheduling and preparation. I am quite sure that without Beatriz we would still be waiting for our immigration appointment. The onboarding process and documents collection process was incredibly smooth and professional.

Language Test for Portuguese Citizenship

The CIPLE (Certificado Inicial de Português Língua Estrangeira) is the required Portuguese language exam for anyone applying for Portuguese citizenship. It’s an A2-level test, meaning it checks for a basic understanding of the language — just enough to communicate in everyday situations.

If you’re eligible for Portuguese nationality, taking and passing the CIPLE is part of the process.

Here’s what to expect from the exam:

  • Oral Comprehension (30%) – 30 minutes
  • Reading & Writing (45%) – 90 minutes
  • Oral Expression (25%) – 15 minutes

The entire exam takes about 2 hours, and to pass, you’ll need a minimum score of 55%. There’s also a €72 exam fee.
