MADRID – Spain’s left-wing government has finalized a sweeping immigration reform that will grant legal residence and work permits to approximately 500,000 undocumented migrants currently living in the country .
The measure, enacted via royal decree on Tuesday and bypassing a parliamentary vote, stands in stark contrast to stricter border policies being adopted across much of Europe . Prime Minister Pedro Sánchez defended the plan as both a moral and economic imperative, framing it as a necessary step to sustain the nation's aging workforce and pension system .
Key Details of the Legalization Scheme
Under the new rules, which open for applications on April 16 and close at the end of June, undocumented migrants can apply for a one-year, renewable residence and work permit . To be eligible, applicants must meet the following criteria:
- Residency Requirement: Proof of continuous residence in Spain for at least five months prior to the application .
- Entry Deadline: Proof of arrival in Spain before January 1, 2026, a cutoff designed to prevent a sudden surge in new arrivals seeking to benefit from the amnesty .
- Clean Record: A clean criminal background check .
The government estimates that bringing these workers into the formal economy will bolster the social security system through increased tax contributions. Official data indicates that foreign nationals already account for a significant portion of economic growth, comprising over half of the employment gains in the final quarter of 2025 . Think tanks and financial bodies have long warned that Spain requires hundreds of thousands of new workers annually to offset its low birth rate and support public services .
Political Opposition and Logistical Hurdles
The amnesty has drawn sharp criticism from the conservative opposition People's Party (PP), which has labeled the plan an "outrage" and argues it will incentivize further illegal migration . PP leaders have vowed to challenge the decree in court, although the government maintains the action is legally sound .
Beyond the political battle, the plan faces significant logistical hurdles. Immigration officers' unions are threatening strike action starting April 21, warning that understaffed offices lack the resources to process what could be an avalanche of applications . To manage the load, only five of the country's 54 immigration offices will handle the process, with support from social security branches and NGOs .
While many European neighbors are tightening internal borders, Spain's move marks the largest regularization effort in the country since 2005 and enjoys support from a broad coalition of NGOs and the Catholic Church .
