Spain's government announced plans this week to legalise 500,000 undocumented migrants and asylum seekers. This bold decision aims to boost "economic growth and social cohesion." The conservative People's Party leader Alberto Núñez Feijóo criticized it as rewarding "illegality" and warned it could "overwhelm our public services." Far-right Vox leader Santiago Abascal called it an "invasion" to replace Spaniards with foreigners. For many migrants, like a Bangladeshi man in Madrid, the news felt like a miracle. Living without papers, he struggled to earn a living selling umbrellas for €200 to €400 per month. "I’m so excited," he said. "It’s like a gift from God that will help keep me going." Mohammed Elahi Alam Alam from the Valiente Bangla Association welcomed the move as needed and a counter to Vox's plans to deport millions. "Who’s going to work in the fields? Immigrants. Who’s going to work in restaurants? Immigrants," he said. Rosa, a Colombian migrant working informally as a cleaner, saw the regularisation as a chance for better pay and job protections. "Many of us have sacrificed so much," she said, adding that some employers exploit undocumented workers. This is not Spain’s first regularisation programme; similar efforts from 1986 to 2005 showed economic benefits. Research found tax revenues rose about €4,000 per regularised immigrant yearly. Labour economist Joan Monràs said no "pull effect" caused more migrants to come, but immigrants' careers improved. Prime Minister Pedro Sánchez defended immigration as key for Spain’s ageing population. He said, "Migration has been one of the great drivers of the development of nations." Despite political backlash and fake news, the measure grants residency but not citizenship or voting rights. Even Elon Musk weighed in on social media, calling the policy "electoral engineering," to which Sánchez replied, "Mars can wait. Humanity can’t." Catholic and migrant groups praised the decision as "an act of social justice." Edith Espínola from Regularisation Now! said it helps migrants regain dignity and rights with this "plastic card" recognizing them as residents. The decree offers work, study, and a more humane life for thousands now living in the shadows.
