Spain's left-wing government has launched a sweeping regularisation programme set to grant legal residency to approximately 500,000 undocumented migrants currently living and working in the country — a move that bucks the increasingly hardline immigration policies taking hold across Europe and the United States. According to Antigua News Room, the programme was initiated on Tuesday by Prime Minister Pedro Sanchez's Socialist-led administration.
Foreign nationals with clean criminal records who arrived in Spain before the end of 2025, and who can demonstrate at least five months of residency, are now eligible for renewable one-year residence permits. Those who applied for asylum in the country before December 31 will also qualify.
The mass regularisation — the first of its kind in Spain in more than 20 years — originated from a citizen-backed proposal signed by approximately 700,000 people and supported by hundreds of civil society organisations, including the Catholic Church.
While the majority of immigrants in Spain hold legal status, the country's booming economy has drawn hundreds of thousands of largely working-age people into its informal labour market. Undocumented workers are employed on construction sites, farms, shops, restaurants, and private households. Most come from Spain's former colonial territories across Latin America and North Africa, including Venezuela, Colombia, Ecuador, and Morocco.
Contrary to the dramatic imagery of migrants crossing barbed-wire fences or navigating the seas toward the Canary Islands, most undocumented people in Spain entered the country legally and subsequently overstayed their visas, finding employment in what is commonly referred to as the country's "black economy."
Sanchez has consistently argued that migrants are not a drain on social services, as critics contend, but rather a vital pillar supporting Spain's welfare state. He frames the formalisation of half a million workers as a direct investment in the country's social security system, which faces mounting pressure from an ageing native-born population.
The initiative stands in sharp contrast to the direction taken elsewhere. European Union member states backed harsher migration measures in December of last year, permitting the deportation of rejected asylum seekers to offshore "return hubs." France, meanwhile, recorded rising deportation figures alongside a reduction in legal pathways for undocumented workers.
Migration Policy Institute Europe deputy director Jasmijn Slootjes said Spain's decision reflects deeper demographic and economic anxieties. "If you look at the demographic decline, the fertility rate in Spain is the lowest in Europe — so it's really, really low," she said. "There were a lot of skill shortages, labour shortages, and de facto a lot of irregular migrants are working, although in informal work. And through regularising you can, of course, get more tax payments, and you also get better matching to their skills — because people can actually work at their skill level. So it's a very pragmatic approach."
Slootjes noted that the Sanchez government — which announced the measure as part of an agreement with its former coalition partners, the leftist PODEMOS party — has positioned migration as a fundamental driver of Spain's economic growth.
Official data released on Tuesday showed that 52,500 of the 76,200 people who boosted employment figures in the final quarter of 2025 were born overseas. That same quarter marked Spain's lowest unemployment rate in 18 years.
"That's really something that's being mentioned time and again — this link to the economy, maintaining social welfare access and a healthy, competitive country. That is really a core argument in all of this, and the evidence is indeed pointing that way," Slootjes said.
She also highlighted what she described as a defining statement from the Prime Minister himself: "He says, 'Spain needs to choose between being an open and prosperous country, or a closed-off and poor country.'"
