Spain's mass migrant legalization

The program offers a one-year renewable residence permit for those who have lived in Spain for at least two years and can prove they have a work contract.

Thousands of migrants have already queued up to register in the first few days of the initiative.

The socialist government argues the measure is necessary to address labor shortages and integrate long-term residents into the formal economy.

Critics have expressed concerns that the program could encourage more illegal immigration and strain public services.
