Spain has launched an extraordinary regularization programme that could give legal status to large numbers of undocumented migrants, but the eligibility criteria mean that not everyone living in the country irregularly will benefit. An InfoMigrants analysis breaks down who qualifies and who remains outside the scheme.

The programme forms part of a broader immigration reform approved in 2025, which took effect on 20 May 2025. It relaxes several long-standing requirements — notably the period of prior residence and the strict documentation rules that previously blocked most applicants.

What does the regularization change?

The reform lowers the barriers that made earlier regularization attempts fail in practice. Under the new rules:

• Applicants no longer need to prove uninterrupted residence with exhaustive documentation.
• The reform simplifies the procedure for obtaining residency permits and opens a pathway from temporary status toward longer-term residence.
• Facilitated access to the labour market is a central pillar, responding to employers and sectors that have long reported labour shortages.

Spanish authorities have framed the measure as both a rights-based correction and a practical response to demographic and economic needs. Migrants already living and working in the country without papers are the core target group.

Who benefits?

The main beneficiaries are undocumented migrants who can demonstrate roots in Spain — in practice, people with time spent in the country, family ties, or work history. The relaxation of documentation requirements matters most here: under the old rules, applicants who could not produce utility bills, rental contracts or formal employment records for every month of their stay saw applications rejected.

The reform also matters for migrants in vulnerable situations. InfoMigrants reports that the new framework gives officials more discretion to recognize individual circumstances, reducing the risk that a missing document alone sinks an application.

Employers in agriculture, construction, hospitality and care work also stand to gain, because regularization moves workers out of the informal economy and into formal contracts.

Who is left out?

Not everyone qualifies, and the InfoMigrants analysis highlights the gaps. The scheme sets conditions, and migrants who cannot meet them remain in irregularity. Key exclusions include:

• Applicants with certain criminal records.
• People who arrived too recently to satisfy the residence requirement.
• Those who still cannot evidence their presence in Spain, even under the relaxed standard.

Advocacy organizations have warned that the people most likely to be excluded are often the most vulnerable — recent arrivals, victims of exploitation who worked entirely off the books, and people whose documentation was lost or never issued.

Why does this matter now?

Spain hosts one of the larger undocumented populations in the European Union, and successive governments have struggled to bring those numbers down through ordinary procedures. The extraordinary regularization is designed to do what standard routes could not: convert irregular presence into legal status at scale.

The measure also carries political weight. Regularization divides opinion in Spain and across the EU, with supporters citing integration and labour-market data, and critics arguing that regularization encourages further irregular arrivals. The InfoMigrants analysis situates the Spanish case within this wider European debate.

What should affected migrants do?

Applicants should rely only on official channels. The Spanish Ministry of Inclusion, Social Security and Migration, along with the official immigration portals, publish the application requirements, forms and deadlines. Independent legal advice from licensed practitioners or accredited NGOs is the safest route, because eligibility depends on individual circumstances.

No applicant should pay intermediaries promising guaranteed permits. Officials and migrant-support organizations have repeatedly warned that irregular-status communities are a prime target for fraud during regularization windows.

The road ahead

The regularization programme marks one of the most significant shifts in Spanish migration policy in years. Its success will be measured in two ways: how many people manage to regularize, and how many remain excluded once the process runs its course. InfoMigrants' central finding is that the answer depends heavily on where an individual migrant falls within the eligibility criteria — the difference between a residence permit and continued irregularity can come down to a single requirement.
