What is Dual Citizenship?

Dual citizenship, also referred to as dual nationality or second citizenship, is a legal status where an individual is recognized as a citizen in two countries at the same time. Dual citizenship can be obtained through various routes, including naturalization, descent, and more, to be explored in detail later on. Having a second passport is ideal for Americans moving to Portugal, as it allows them to legally set up a base in the country.

Does Portugal Allow Dual Citizenship?

Yes, while Portugal does not have any specific dual nationality agreements, the Portuguese government does allow second citizenship with a number of countries and will not require you to give up your original citizenship to become a Portuguese citizen and simultaneously an EU citizen. Here are a few things you need to know before you apply for Portuguese citizenship.

Dual Citizenship in Portugal

Now that we know Portuguese law allows dual citizenship and for individuals to maintain ties with their home country, it is important to note that to gain citizenship, you must have lived in Portugal for at least five years as a legal resident. To meet this residency requirement, you could also have been married or living in a non-marital partnership with a Portuguese national for over three years. Additional requirements to obtain Portuguese nationality include Portuguese language proficiency, a clean criminal record certificate, and proof of Portuguese residency, such as a legal residence permit.

US Policy on Dual Citizenship

According to the US Department of State’s Bureau of Consular Affairs, the United States of America does recognize dual citizenship and allows American citizens to have foreign citizenship without losing their American citizenship. US law will also not require US citizens to choose between their US citizenship and Portuguese nationality or other foreign nationality, keeping their US citizenship risk-free. However, dual nationals are required to obey the laws of both countries and may be required to use their US passport instead of their second passport to enter and leave the United States.

How to Move to Portugal from the USA and Get Dual Citizenship

As mentioned before, there are a variety of routes to obtaining Portuguese citizenship.

Portugal Dual Citizenship Eligibility

Take a look at the following eligibility criteria to acquire Portuguese citizenship as well as Portuguese dual citizenship:

Portuguese Citizenship by Investment

With the Portuguese Golden Visa, Americans have a pathway to acquire Portuguese citizenship by making a qualifying investment in the country and contributing to economic growth. This visa scheme speeds up the process for foreign nationals and non-EU/non-EEA citizens to obtain a legal residence permit in Portugal. Golden Visa holders are granted a temporary residence permit in exchange for making a minimum investment starting from €250,000. After five years of maintaining the temporary permit and their investment, Golden Visa holders can then apply for Portuguese citizenship or permanent residence.

Portuguese Citizenship by Descent

portugal citizenship by descentPortuguese Law recognizes nationality through jus sanguini (right of blood, which is citizenship derived from Portuguese ancestors) and jus soli (right of soil, which refers to persons born in Portuguese territory). THis means that those with Portuguese ancestry may be eligible for acquiring Portuguese citizenship based on descent.

You can apply for Portuguese citizenship by descent if you have a Portuguese ascendant. This means you would be eligible if you have Portuguese parents or at least one parent born in Portugal. You can also qualify via this route through a Portuguese grandparent who retained their nationality.

To acquire citizenship through this route, you must submit the birth certificate(s) of your Portuguese parent(s) stating that they were born in Portugal as proof of Portuguese descent.

The Portuguese government also lets you apply to obtain citizenship by descent if you have a Portuguese grandparent. In this case, you must also submit the birth certificate of your Portuguese grandparent confirming that they are indeed a Portuguese national. To qualify via this route, you must have lived in Portugal for at least three years with demonstrable ties to the Portuguese community (such as proficiency in the Portguese language and cultural engagement).

For US citizens, it is important to note that if you have Portuguese parents or your parents have citizenship from another country, you may be granted citizenship and a second passport.

Portuguese Citizenship by Marriage: Spousal Eligibility

You can also obtain Portuguese citizenship through spousal eligibility. After being married to a Portuguese citizen for three years, you can apply for Portuguese citizenship. You will need to provide the required documents, such as a marriage certificate and a copy of your spouse’s Portuguese citizen card. Portuguese law does not have a minimum residency requirement for this route, and your citizenship in Portugal will remain valid even if you divorce or separate in the future.

Portuguese Citizenship Under the Jewish Law of Return

The Portuguese parliament passed legislation in 2013 called “Law of Return” granting descendants of Sephardic Jews expelled during the Inquisition a path to citizenship. Eligibility hinges on proving Sephardic ancestry and affiliation with Portugal’s Sephardic Jewish community. Unlike Israel’s Law of Return, requiring residency, Portugal primarily focuses on lineage and cultural ties to the Portuguese Sephardic community. This program, however, faces potential changes, so it’s important to consult with immigration specialists to make sure that you’re up to date with any changes to the legislation.

Portuguese Citizenship by Naturalization of Foreign Residents

Living legally in Portugal for at least five years is one of the main routes to obtaining Portuguese nationality. This is a lengthy process referred to as citizenship by naturalization and requires that the applicant has a legal residence permit during the application period. The naturalization process allows long-term residents to obtain citizenship after meeting certain eligibility criteria, including Portuguese language proficiency (read Portuguese language test to learn more). Visa options such as the Portugal D3 Visa, Portugal D7 Visa, and Portugal D8 Visa follow a naturalization process and do not require an investment like the Portugal Golden Visa does.

Non-EU nationals residing in Portugal usually begin the journey with a temporary residence permit through one of Portugal’s visa options, which is valid for one year and renewable for two-year periods. After five years of holding a temporary residence permit, you will be able to apply for a permanent residence permit. Both the temporary and permanent residence permits will count towards the five-year residency requirement for naturalization.

Citizenship through residence in Portuguese overseas territories

You can claim Portuguese citizenship in certain cases if you are a resident of one of the following former Portuguese colonies:

  • Angola
  • Cabo Verde
  • Portuguese India
  • Guinea-Bissau
  • East Timor
  • Macao
  • Mozambique
  • São Tomé and Príncipe

You’ll need to prove that you are either a descendant of Portuguese nationals or are part of a community that practices Portuguese values and traditions.
