Portugal's Nationality Law Sits on the President's Desk — Three Scenarios for What Happens Next
Parliament doubled the residency requirement for citizenship to 10 years on April 1. The decree now sits with President Seguro, who can sign it, veto it, or send it to the Constitutional Court.
On April 1, Portugal's parliament approved the most significant overhaul of the country's nationality law in a generation. The decree passed 152 to 64, clearing the two-thirds supermajority required for organic legislation, after the governing Social Democratic Party (PSD) struck a last-minute deal with the right-wing Chega party that sidelined the Socialists and their demand for transitional protections.
The bill now sits with President António José Seguro — a former Socialist Party leader who took office in February after winning January's presidential election. His decision will determine whether hundreds of thousands of foreign residents face a dramatically longer path to Portuguese citizenship, or whether the law returns to parliament or the courts for further scrutiny.
What the Law Changes
The core shift is stark. The residency requirement for naturalisation doubles from five years to ten. Citizens of Portuguese-speaking (CPLP) countries and EU nationals get a reduced threshold of seven years — still a 40 per cent increase over the current rule. Children born in Portugal to foreign parents, who currently acquire nationality if a parent has been legally resident for one year, would now need to demonstrate five years of legal residency.
The criminal record bar also tightens: a prison sentence of three years or more — down from five — disqualifies an applicant. And critically, the PSD-Chega version contains no transitional provisions. Anyone mid-process under the old rules when the law takes effect would be subject to the new requirements immediately.
Scenario 1: Promulgation
Seguro signs the decree into law, and it is published in the Diário da República. From that date, the new residency requirements apply. This is the fastest path — potentially days or weeks away — but also the least likely given Seguro's political background. As PS leader from 2011 to 2014, he championed inclusive immigration policies. Promulgating a law his former party voted against, and which lacks the transitional safeguards the PS demanded, would be a sharp departure from his known convictions.
That said, presidents are constitutionally expected to respect clear parliamentary majorities. The 152-vote supermajority is difficult to dismiss as illegitimate, and Seguro may calculate that a veto would only delay the inevitable.
Scenario 2: Political Veto
The president vetoes the decree and sends it back to parliament with a reasoned message. Under the Portuguese constitution, the Assembly can override a presidential veto with an absolute majority — 116 votes — which the PSD-Chega bloc comfortably commands. A veto would therefore be symbolic rather than terminal: it would force a second vote, buy time for public debate, and put the absence of transitional protections back on the agenda.
This is arguably the most politically elegant path for Seguro. He registers his objection, the PS can claim a partial victory on framing, and parliament ultimately passes the law anyway — but possibly with minor concessions on the transitional regime.
Scenario 3: Referral to the Constitutional Court
Seguro requests a preventive constitutionality review before signing. This is what happened in November 2025, when then-President Marcelo Rebelo de Sousa referred an earlier version of the nationality law to the Constitutional Court. The court's ruling struck down several provisions, which is partly why parliament had to vote again in April.
A fresh referral would suspend the law's entry into force until the court rules — a process that could take weeks or months. The legal questions are genuine: the retroactive application of new residency requirements to people already in the naturalisation pipeline raises serious proportionality concerns under both the Portuguese constitution and EU law.
What It Means for Residents
For the estimated 180,000 foreign nationals who have been legally resident in Portugal for between five and ten years, the stakes are immediate. Under the current law, many are eligible to apply for citizenship now. Under the new law, they would need to wait years longer — unless transitional provisions are added or the Constitutional Court intervenes.
Immigration lawyers report a surge in citizenship applications filed in recent days, as residents race to submit before the new rules take effect. Whether those applications will be processed under the old or new framework depends entirely on what President Seguro decides — and how quickly he decides it.
