Why Spain is giving undocumented migrants a legal way to stay

The move gives hundreds of thousands of people a path out of limbo, even as many countries tighten immigration rules.

• Spain to offer temporary legal residency to undocumented migrants in-country
• Migrants must prove arrival before Dec 2025 and 5 months' residence to qualify.
• Residency permits valid for one year, allowing legal work and possible renewal

Spain has taken a sharply different approach to immigration from much of the Western world, approving a decree that will allow hundreds of thousands of undocumented migrants already living in the country to apply for temporary legal residency.

The measure, approved unexpectedly on Tuesday by the Socialist-led government of Prime Minister Pedro Sánchez, offers a pathway out of legal uncertainty for migrants who can prove they arrived in Spain before December 2025 and have lived in the country for at least five months. Successful applicants will receive one-year residency permits that allow them to work, with the option to renew, the New York Times reported.

Why Spain is taking a different route

Spain’s migration minister, Elma Saiz Delgado, said the decision was driven by both social and economic considerations. Migrant labour, she said, is essential to sectors such as agriculture, tourism and care work, and regularising undocumented workers would strengthen social cohesion while supporting economic growth.

The decision places Spain at odds with a broader international shift toward tougher immigration enforcement. In the United States, the Trump administration has launched an aggressive campaign of arrests and deportations. Britain has tightened refugee rules, Greece has introduced prison sentences for rejected asylum seekers who remain in the country, and Italy has sought to process asylum claims outside its borders.

A large undocumented population already embedded in the economy

Spain does not publish official figures on the number of undocumented migrants living in the country, but estimates from research institutions suggest the total could range from 500,000 to one million, out of a population of nearly 50 million.

Many of these migrants are already deeply embedded in the labour market, often working in precarious conditions without legal protections. Officials argue that bringing them into the formal system is more realistic than continuing to police an underground workforce.

How the new residency scheme will work

Under the decree, applications will be accepted only between April and June. Migrants must show proof of arrival before December 2025 and demonstrate at least five months of residence in Spain. People with criminal records will be excluded.

The residency permits will be valid for one year and will allow recipients to work legally. The government says limiting eligibility to migrants already present in Spain reduces the risk of encouraging new arrivals.

Relief on the ground for migrants

For migrants themselves, the decision has been met with relief. Sady Traoré, a 28-year-old from Mali who works in citrus fields in eastern Spain, said the decree brings him closer to what he described as a basic aspiration: living and working legally, without fear.

He arrived via the Canary Islands in 2024 but has since been unable to secure an appointment to apply for asylum, leaving him in legal limbo despite steady employment.

Economic impact and labour market realities

The push for regularisation gained momentum during the Covid-19 pandemic, when undocumented migrants continued working through lockdowns, often in essential roles. Economists at the European Central Bank have credited migrant labour with easing shortages and helping Spain outperform many peers economically.

Ismael Gálvez, an economist at the University of the Balearic Islands, said the measure was unlikely to put significant pressure on the labour or housing market for native-born Spaniards, since it applies only to people already in the country. Migrants, he noted, tend to compete primarily with other migrants for jobs.

Political backlash and legal challenges

Opposition parties were quick to criticise the move. The conservative Popular Party accused the government of using the decree for political advantage, while the far-right Vox party said it would challenge the measure in court, portraying it as an invitation to further migration.

Despite the criticism, Spain has taken similar steps before. Since the mid-1980s, the country has carried out at least eight large-scale regularisation campaigns under governments of different political stripes, granting legal status to more than one million migrants.

A calculated bet on regularisation

For the Sánchez government, the decree is being framed not as a radical departure but as a pragmatic response to an existing reality. In an international climate increasingly defined by enforcement and exclusion, Spain is betting that legal recognition will deliver more stability than prolonged uncertainty — for migrants, employers and the state alike.
