Spain has opened one of Europe's largest-ever immigration regularisation programmes, with nearly 43,000 people submitting online applications in the first three days alone. In-person applications began on Monday at more than 370 post offices, 60 social security offices, and a small number of dedicated migration offices across the country. The programme, announced in January and finalised this month, offers undocumented migrants a one-year, renewable residence permit on the condition that they have lived in Spain for at least five months and hold a clean criminal record. Applicants have until the end of June to submit their paperwork.

The scale of the initiative is considerable. Spain's government estimates it could regularise around 500,000 people, while Funcas, a respected Spanish economic think tank, puts the eligible population closer to 840,000. Questions have been raised about whether the administrative infrastructure can process such a large volume of cases within the tight deadline, though early reports from applicants in Madrid and Barcelona described the process as manageable, if slow. "It's pretty simple since I made an appointment online," said Nubia Rivas, a 47-year-old Venezuelan migrant in Madrid. "The process here is a little slow, but it's fluid." Another Venezuelan applicant, Johana Moreno, who works as a cleaner after training as an archivist in her home country, said legalising her status meant the chance "to be well, to work, to contribute — to pay our taxes."

Prime Minister Pedro Sánchez has framed the measure in both moral and economic terms, calling it "an act of justice and a necessity" and arguing that people already living and working in Spain should do so "under equal conditions." Spain's workforce needs are a central justification: with an ageing population and a growing economy, the government contends that regularising workers — particularly in agriculture, tourism, and the service sector — is essential to sustaining the social security system. Business associations and trade unions have both expressed support.

Spain's approach stands in notable contrast to the broader European mood on migration, where numerous governments have moved to tighten borders and increase deportations. Around 10 million of Spain's roughly 48 million residents were born abroad — approximately one in five — with large communities originating from Colombia, Venezuela, and Morocco, many having left their home countries due to poverty, violence, or political instability. Crucially, this is not a policy innovation for Spain: the country carried out six similar regularisation programmes between 1986 and 2005, including under centre-right governments, lending the current measure a degree of cross-party historical precedent even as it draws criticism from the political right today.
