Spain Bucks European Trend, Legalizes Half Million Undocumented Migrants

Half a million people will gain legal status in one sweeping move. While the rest of Europe builds walls, Spain is opening doors wider than ever.

The Spanish government announced plans last week to legalize undocumented migrants who can prove they've lived in the country for at least five months before December 31, 2025, and have no criminal record. It's the largest regularization program in two decades.

"This is a historic day for our country," said Elma Saiz, Spain's Minister of Inclusion, Social Security and Migration. The program offers initial one-year residence permits, renewable thereafter. "We are reinforcing a migratory model based on human rights, integration, coexistence, and which is compatible with economic growth and social cohesion."

The Numbers Tell a Story

Spain's undocumented population has exploded. Conservative think-tank Funcas found numbers jumped from 107,409 in 2017 to 837,938 in 2025—an eight-fold increase. Most arrivals come from Colombia, Peru, and Honduras.

This surge coincides with Spain's economic outperformance. The country expects close to 3% growth in 2025, outpacing major EU economies. Unemployment, long Spain's Achilles' heel, dropped below 10% for the first time since 2008—figures released just this week.

Prime Minister Pedro Sánchez has consistently framed immigrants as bringing "wealth, development and prosperity" to Spain, highlighting their contributions to the social security system.

Europe's Outlier

Spain's approach stands in stark contrast to European trends. Germany tightens border controls, France harshens immigration laws, and the UK implements its points-based system. Spain swims against the current.

The decision follows pressure from far-left party Podemos, whose former minister Irene Montero argues that "providing rights is the answer to racism." A civic legislative proposal supporting mass regularization gathered 700,000 signatures but had been stalled in parliament.

By using royal decree, the government bypassed parliamentary approval entirely—a move that speaks to both urgency and political pragmatism.

The Backlash

Opposition voices are sharp and immediate. Conservative People's Party leader Alberto Núñez Feijóo warns the measure will "increase the pull effect and overwhelm our public services." Far-right Vox party spokeswoman Pepa Millán calls it an attack on Spanish identity and promises Supreme Court appeals.

The criticism reflects broader European anxieties about migration's impact on public resources, cultural cohesion, and political stability.

Historical Context

This marks Spain's first large-scale regularization since 2005. Between 1986 and 2005, both Socialist and conservative governments implemented various legalization programs, granting status to an estimated half million migrants.

Applications begin in April and run through June's end. The process is designed to be straightforward—a deliberate choice that signals Spain's commitment to making integration, not bureaucracy, the challenge.
