Spain Takes a Different Path on Migration as Much of Europe Tightens Borders

While immigration continues to dominate European politics as a source of anxiety and polarization, Spain is moving in the opposite direction. The government has announced plans to grant legal residency to a large share of undocumented migrants already living and working in the country, positioning itself as a notable outlier among Western democracies.

The Socialist-led administration of Prime Minister Pedro Sánchez says undocumented migrants who have lived in Spain for at least five months before the end of last year and who have no criminal record will be able to legalize their status in the coming months. Officials estimate that around 500,000 people could benefit, though some analysts believe the final number may be higher.

The government argues the move is pragmatic as much as it is humanitarian. Spain’s economy has shown resilience, unemployment has fallen, and several sectors face persistent labour shortages. Bringing undocumented workers into the formal system is expected to increase tax revenue and social security contributions, while reducing undeclared work.

To speed up implementation, the government plans to enact the measure through a royal decree, avoiding a parliamentary vote it might struggle to win due to its lack of a majority. Support for the initiative comes from labour unions, many business groups and the Catholic Church, all of which see regularization as a way to stabilise the workforce and improve social cohesion.

Large-scale migrant regularizations are not unprecedented in Spain. Over the past five decades, governments across the political spectrum have carried out similar measures several times, most recently in 2005, when more than half a million people gained legal residency. Experts note that Spain’s relatively calm reaction reflects this history, even if the topic remains politically sensitive.

That does not mean the policy is uncontested. The far-right Vox party has built much of its recent momentum on opposition to immigration, arguing that large inflows strain public services and contribute to insecurity. Its leader has warned that the regularization could encourage further irregular migration. However, criticism from the mainstream conservative People’s Party has been more restrained, focusing on how the policy will be implemented rather than rejecting the principle outright.

Estimates suggest that around 840,000 undocumented migrants currently live in Spain, the vast majority originating from Latin America. Countries such as Colombia, Honduras, Peru and Venezuela have been among the main sources in recent years, as people flee economic hardship, violence and political instability. Most arrive legally on temporary visas and later overstay, often relying on family or community networks to find work.

Researchers point out that shared language and cultural ties make integration easier in Spain than in many other European countries, where migration is more heavily linked to the Middle East or Africa. Public opinion surveys consistently show Spaniards to be among the most positive in Europe about immigration’s impact, even among voters on the political right.

Economic studies cited by the government suggest that previous regularizations strengthened public finances, with each newly legalized worker contributing several thousand euros per year on average. Supporters argue this undercuts the case for keeping large numbers of workers in legal limbo.

Politically, the decision raises the likelihood that immigration will become a central issue ahead of Spain’s next national elections in 2027. Vox is expected to campaign aggressively against the policy, while the governing Socialists may seek to present regularization as proof that immigration can support growth rather than undermine it.

Whether Spain’s approach remains an exception in Europe is uncertain. Analysts warn that polarization is likely to deepen, and that shifting political winds could narrow the space for consensus. For now, however, Spain is betting that bringing migrants out of the shadows will pay off economically — and that voters will ultimately agree.
