Portugal missed an Aug. 16 deadline to update the regulations behind its new citizenship law, leaving some of the new requirements without clear procedures.
The country's new nationality law took effect May 19 and gave the government 90 days to amend the Regulation of Portuguese Nationality. That deadline has passed. The regulation still shows its most recent amendment as July 23, 2025, before the new law took effect.
For Americans applying now, the main rules are clear. The standard residence requirement increased from five years to 10, and new applicants also face additional language, cultural, civic and financial requirements. What's far less clear is how some of those requirements will be applied.
Americans now face a 10-year wait
Most Americans, as well as people of other non-EU nationalities, must now complete 10 years of legal residence before they can apply for Portuguese citizenship. EU citizens and nationals of Portuguese-speaking countries generally face a seven-year requirement.
The longer timeline survived Portugal's constitutional review of the broader nationality overhaul. AER previously covered the court's ruling on the citizenship changes. The change matters because Portugal has become a major destination for Americans. Government data counted 19,258 U.S. citizens living in the country in 2024.
The law also added requirements involving Portuguese language and culture, national history and symbols, civic knowledge and financial self-sufficiency.
The problem is that the government has not yet updated the regulations that normally spell out how applicants prove those things.
The regulations are still outdated
The current nationality regulation still reflects the old system. Portugal's own government guidance is also uneven. One Justice Ministry page now refers to the 10-year residence requirement, while other public information still reflects older rules.
That doesn't change the law, but it does make the application process less clear.
The missing rules matter most for requirements that need an administrative standard, such as how applicants prove cultural knowledge, civic knowledge or financial support.
The deadline was written into law
The Aug. 16 date was not a target set by the government. It came directly from the nationality law. A petition filed with parliament also flagged the deadline and asked lawmakers to monitor whether the government met it. It didn't.
That does not bring back the old five-year rule or pause the new law. The new citizenship rules remain in effect. It means the law is ahead of the regulations.
What this means for Americans in Portugal
People who already had citizenship applications pending when the new law took effect remain under the previous rules. Americans who hadn't yet applied generally face the new 10-year requirement and the added conditions.
For those applicants, the missed deadline creates uncertainty around procedure, not eligibility. The biggest open questions are how Portugal will test or document the new cultural and civic requirements and what proof will satisfy the financial-support requirement.
Until the government updates the regulation, those details remain unsettled.
