Can I Have Dual Citizenship: Brazil and Portugal?

The short answer: yes, it is possible

One of the most frequent questions from Brazilians considering the Golden Visa or other residency routes in Portugal is this: if I obtain Portuguese citizenship, do I lose my Brazilian citizenship? The answer is no. Brazil explicitly allows dual citizenship — a Brazilian can obtain Portuguese citizenship and maintain their Brazilian nationality, holding both valid passports simultaneously.

What Brazilian law says about dual citizenship

The Brazilian Federal Constitution of 1988 generally prohibits the accumulation of nationalities — but establishes explicit exceptions. The most relevant exception for this context is Article 12, §4, clause II, item "b": a Brazilian does not lose their nationality when acquiring another citizenship through naturalisation in a country that imposes naturalisation as a condition for remaining in its territory or for exercising civil rights.

Portugal, for these purposes, is exactly that country: naturalisation in Portugal is a voluntary route to acquiring citizenship, not an imposition. Therefore, Portuguese naturalisation by a Brazilian is, in practice, widely accepted as compatible with maintaining Brazilian citizenship — and the vast majority of Brazilians naturalised as Portuguese retain both nationalities without any issue.

What Portuguese law says

Portugal, for its part, does not require the renunciation of prior nationality to grant Portuguese citizenship. A Brazilian applicant who naturalises as Portuguese maintains their rights and duties as a Brazilian citizen — including, if they reside in Portugal, any obligations to declare assets to the Brazilian state and military service (for those still subject to it).

What having two passports means in practice

Holding both a Brazilian and a Portuguese (European) passport simultaneously has very concrete practical implications:

  • Expanded global mobility: the Portuguese passport allows visa-free entry to all EU countries, the Schengen area, and dozens of other countries worldwide — including several where the Brazilian passport has more limited access.
  • Right to reside and work in the EU: with the European passport, the holder can reside and work in any European Union country without needing a visa or additional residence permit.
  • Maintenance of all Brazilian rights: the holder can continue to vote in Brazil, access Brazilian public services, and benefit from all the rights of a Brazilian citizen — including inheriting assets in Brazil, opening a business, etc.

Obligations that remain with dual citizenship

Having two passports does not mean having no obligations in either country. A Brazilian with Portuguese citizenship continues to have tax obligations in Brazil if they have income or assets there — and may have tax obligations in Portugal if they reside there and are considered a tax resident. Dual citizenship is not, by itself, a tax optimisation mechanism: each person's tax situation depends on where they reside, where they earn income, and what the applicable tax treaties say.

Note: Brazil-Portugal dual citizenship is legally possible and widely practised. But the tax, social security, and other obligations arising from each citizenship should be analysed with specialised advice, depending on each person's specific situation.

How to reach dual citizenship: the available paths

There are several routes for a Brazilian to obtain Portuguese citizenship:

  • Naturalization by residency: after 7 years of legal residency in Portugal (via CPLP). The Golden Visa is one of the ways to acquire this residency.
  • Luso-Brazilian Treaty route: after 2 years of residency with equality of rights status.
  • Citizenship by descent: for those with Portuguese grandparents or great-grandparents — regardless of residing in Portugal.
  • Marriage to a Portuguese citizen: after 3 years of marriage or recognised civil union.
