Portuguese President Marcelo Rebelo de Sousa has signed a revised version of the citizenship law that significantly tightens naturalization requirements for foreigners. The law will take effect upon publication in the Diário da República.
The main change concerns the length of residence required to apply for citizenship. For most foreigners, it increases from 5 to 10 years, and for citizens of EU countries and Portuguese-speaking Commonwealth states, to 7 years. Additionally, the period will be calculated not from the date of application for a residence permit, but from the date the first residence card is issued.
The reform also introduces additional integration requirements. Applicants for citizenship will need to demonstrate proficiency in Portuguese at the A2 level, pass a test on culture, history, and the rights and responsibilities of citizens, confirm their commitment to democratic principles, prove sufficient means of support, and demonstrate no serious criminal convictions.
A separate part of the reform, concerning the possibility of losing citizenship in the event of serious crimes, remains under review by the Constitutional Court. Previously, the court had already ruled unconstitutional a number of provisions related to automatic denial of citizenship and vague grounds for its revocation.
For foreigners who viewed Portugal as one of the fastest EU jurisdictions for obtaining citizenship through legal residence, the reform means a significant lengthening of the planning horizon. This could have a particularly noticeable impact on residence permit holders and investors under the Golden Visa program: the residency program itself, according to available data, remains unchanged, but the path from residency to citizenship is becoming longer.
The tightening of rules comes amid rapid growth in the number of foreigners in Portugal. According to AIMA, as of the end of 2024, more than 1.5 million foreign citizens resided in the country, which is roughly double the number from three years earlier. The largest group consists of Brazilians—more than 450,000 legal residents.
According to available estimates, the largest groups of foreigners in Portugal also include citizens of India, Angola, Ukraine, Cape Verde, Nepal, Bangladesh, the United Kingdom, Guinea-Bissau, and Pakistan. According to data cited from preliminary AIMA statistics for 2024, the number of Ukrainians in Portugal was estimated at approximately 79,200 people. Separately, regarding temporary protection, according to the Prague Process, as of February 2025, approximately 56,700 Ukrainians with temporary protection status were residing in Portugal. According to some estimates, the number of Ukrainians in Portugal could reach 300,000.
