The Portuguese passport is one of the most desirable passports in the world, granting visa-free entry or visa on arrival access to 187 countries and territories around the world. 


With Portugal being a State member of the European Union, a Portuguese citizen is also a citizen of the European Union. A Portuguese citizen is allowed free rights of movement and residence in any of the States of the European Union (EU), The European Economic Area (EEA) and Switzerland. Also, the family members of a Portuguese citizen are given the possibility to reside in any EU country. 


There are multiple ways to acquire the Portuguese citizenship. The most common is the citizenship by naturalization. The Government grants Portuguese citizenship, by naturalization, to foreigners who cumulatively meet the following requirements: 


  • They are of age or emancipated under Portuguese law;
  • They have lived legally in Portugal for at least five years;
  • They have sufficient knowledge of the Portuguese language;
  • They have not been convicted with a sentence of imprisonment of three years or more for a crime punishable under Portuguese law; and
  • They do not constitute a danger or threat to national security or defense, by their involvement in activities related to the practice of terrorism, under the terms of the respective law. 


There is also the possibility to acquire the Portuguese citizenship through marriage or non-marital union. According to the Law, a foreigner married to a Portuguese national for more than three years may acquire Portuguese citizenship. Also, a foreigner who lives in a long-term civil partnership for more than three years with a Portuguese national may acquire Portuguese nationality, after an action for recognition of that situation to be filed in the civil court. 


The Portuguese citizenship can also be acquired by investment. The applicant should invest in the country through one of the investment routes allowed by the Golden Visa program, such as in art & culture, scientific research, investment funds, companies and the creation of a certain number of job positions and maintain the investment for at least five years. The applicant only needs to stay in Portugal for at least 14 days during a 2-year period. 


A special regime, in force since 2015, still grants the Portuguese citizenship to descendants of Portuguese Sephardic Jews. Since 2022, the application shall be accompanied by a certificate or another supporting documents proving:


  • Ownership, transferred mortis cause, of rights over real estate located in Portugal, other rights of shareholding in commercial or cooperative companies based in Portugal, OR
  • Regular trips to Portugal throughout the applicant’s life when these facts demonstrate an effective and lasting connection to Portugal.


The Portuguese Parliament did not decide yet, but it is predictable that this special regime will end by 2024.

On 16 July 2025, the Portuguese Parliament approved major changes to the legal framework governing immigration (Law no. 23/2007). The reform ends the manifestação de interesse mechanism, tightens rules for job-seeker visas and family reunification, and sets a final deadline for transitional applications.

The Portuguese Parliament has decided to postpone the vote on the proposed amendments to the Nationality Law until September 2025. The decision was taken in a meeting of the Committee on Constitutional Affairs, Rights, Freedoms and Guarantees, following pressure from several political parties who requested more time to assess the implications of the proposed reform. The delay allows for additional hearings with legal experts, immigrant associations and civil society representatives before a final vote is held in plenary session. The proposed reform introduces significant changes to the current legal framework for acquiring Portuguese nationality. Among the most impactful measures is the extension of the minimum legal residence period required before applying for naturalisation. Under the new proposal, this period would increase from the current five years to seven years for nationals of CPLP countries (Community of Portuguese Language Countries), and to ten years for applicants from all other countries. Another major change concerns the introduction of mechanisms to revoke Portuguese nationality . According to the proposal, naturalised citizens who are convicted of serious crimes — defined as those resulting in prison sentences of five years or more , within ten years of acquiring nationality — could see their Portuguese citizenship revoked by a court decision, based on a proposal from the Public Prosecutor’s Office. In addition, the reform would tighten the requirements for acquiring original Portuguese nationality through birth in Portugal. For children born in Portuguese territory to foreign parents, it would become mandatory that at least one parent has been residing legally in Portugal for a minimum of three years , instead of the current two years. Although the government initially intended to approve these changes before the summer recess, political consensus has not yet been reached. Left-wing parties have raised concerns regarding the constitutionality of retroactive revocation of nationality and the potential impact on the rights of long-term residents and immigrant communities in Portugal. In response, the parliamentary committee agreed to postpone the process and schedule a new round of expert hearings in early September. A final vote on the reform is now expected to take place later that month. Until then, the current version of the Nationality Law remains in force , including the five-year legal residence requirement for naturalisation. Applicants who meet this requirement and wish to apply under the current rules may still do so in the coming weeks.
