More than one million undocumented migrants applied for legal residency in Spain under a mass regularisation scheme [1].

The initiative aims to stabilize the national economy and support the welfare state. By granting legal status to workers, the government seeks to address the challenges of an ageing population and ensure the continued funding of pensions [1, 2].

Prime Minister Pedro Sánchez said the application volume exceeded early projections. While previous government plans suggested granting legal status to 500,000 undocumented migrants [3], the actual number of applicants surpassed one million [1].

The application window opened in late April 2026 and officially closed on June 30, 2026 [4]. The programme allowed migrants across the country to submit requests for residency to move out of the shadows of the undocumented economy.

Spanish officials said that regularisation is a necessary step to sustain the workforce. The Socialist government maintains that integrating these individuals into the formal labor market is essential for long-term economic stability, a move intended to prevent labor shortages in key sectors.

The surge in applications indicates a high demand for legal certainty among the undocumented population in Spain. The government must now process these requests to determine who meets the criteria for residency.

“More than one million undocumented migrants applied for legal residency in Spain”

The disparity between the planned 500,000 grants and the one million applications suggests that the undocumented population in Spain is significantly larger or more motivated than the administration initially estimated. This puts pressure on the Spanish bureaucracy to process a massive volume of paperwork while attempting to balance economic needs with immigration controls.
