Spain’s decision to reform its immigration system has revived a question the European Union has long avoided rather than resolved: how national regularisation policies function inside a borderless continental space, and what consequences they produce beyond the state that adopts them.
Madrid’s initiative is driven by concrete pressures. Spain faces labour shortages, rapid demographic ageing and a substantial backlog of unresolved asylum and residency applications. Expanding legal pathways, regularising undocumented migrants already present in the country and simplifying administrative procedures are presented as pragmatic responses to economic and social realities. Considered in isolation, these measures are defensible. Within the framework of the EU’s free-movement regime, however, their implications extend far beyond Spain.
Once legal residence is granted in a Schengen country, internal borders largely cease to function as meaningful barriers. Mobility across much of Europe becomes effectively frictionless, even when legal status has been obtained under national criteria that differ widely from one member state to another. This is both a cornerstone of European integration and one of its most persistent governance blind spots.
Criticism of Spain’s reform does not amount to opposition to migration itself. The concern is that national regularisation decisions increasingly generate Europe-wide effects without corresponding European-level coordination. When residency is granted under broad eligibility criteria, mobility is no longer confined to Spain’s labour market or integration system. It extends to France, Germany, Italy and beyond, in the absence of harmonised standards, shared monitoring mechanisms or consistent enforcement.
Government announcements indicate that the reform could regularise up to 500,000 undocumented migrants nationwide, subject to conditions such as proof of continuous residence and the absence of a criminal record.
The scale of interest is already evident. This reflects both the size of the community and the perception that Spain’s reform offers not only legal stability, but also potential onward mobility within Europe.
European interior ministries have long acknowledged the phenomenon of secondary movement: migrants regularised in one member state later relocating to another with stronger labour markets, higher wages or more generous welfare systems.
The outcome is policy fragmentation. Integration efforts become uneven, enforcement responsibilities diffuse and public confidence in Europe’s capacity to manage migration coherently weakens. This is not a question of nationality, religion or culture. Framing it that way obscures the real issue: a system in which asymmetric national policies operate inside a unified mobility space.
Spain’s reform also exposes a deeper tension between humanitarian intent and governance capacity. Regularisation can reduce illegality and labour exploitation. Yet without EU-level alignment on background checks, security screening, data interoperability and post-regularisation monitoring, it can also create significant blind spots—particularly when migrants originate from regions affected by instability, informal economies or transnational criminal networks.
Europe has already seen how such gaps are exploited. Smuggling networks, document fraud and informal labour intermediaries operate across borders, adapting far faster than regulatory frameworks. In this context, even well-intentioned national reforms risk being absorbed into a system that lacks sufficient continental oversight.
Spain is not acting recklessly. It is acting within a system that places the burden of managing European-scale migration pressures on national governments, while offering them limited tools for coordination. The deeper failure lies at the European level, and in member states’ continued reluctance to confront the structural contradictions embedded in Schengen.
A credible European migration policy would harmonise entry criteria, security vetting, labour pathways and integration benchmarks. It would strengthen shared databases, enhance intelligence cooperation and acknowledge a basic reality: free movement requires shared governance, not unilateral action.
Spain’s immigration reform, and its likely impact on large migrant communities and on the security and cohesion of other EU states, illustrates the broader dilemma confronting Europe. Free movement without common governance is not openness; it is drift.
And drift—at a moment when Europe is already under political, social and institutional strain—is a risk the Union can no longer afford.
