- Spain requires a residence visa for posted non-EU workers if the assignment exceeds 90 days.
Understanding the Vander Elst Visa
Companies operating in the European single market often need to deploy their workforce across borders quickly. When those workers are non-EU citizens, standard immigration rules can halt operations. The Vander Elst visa solves this issue. It allows an employer based in one EU member state to temporarily post non-EU staff to provide services in another member state without obtaining a new, separate work permit for the destination country.
This mechanism keeps cross-border service delivery practical. By removing the requirement for standard work permits in the host nation, the framework ensures businesses can fulfill contracts efficiently. However, while a full work permit is bypassed, specific administrative steps and mandatory documents remain necessary to secure legal entry and compliance.
The Legal Origin of the Framework
This framework originated from a dispute involving Raymond Vander Elst, a Belgian demolition contractor. In 1989, Vander Elst won a contract to carry out demolition work in France. He attempted to post several of his Moroccan employees, who already held valid Belgian work permits, to the French job site. French authorities objected, which led to a landmark 1994 European Court of Justice (ECJ) ruling in Case C-43/93.
The ECJ ruled that member states cannot require additional work permits for third-country nationals who are already lawfully and habitually employed by an EU-based company providing temporary cross-border services. Forcing an employer to obtain new permits for existing staff restricts the freedom to provide services across borders. This ruling established that a worker's legal status in the home member state must be respected by the host country during temporary assignments.
Later, some member states tried to restrict this freedom by requiring workers to be employed for a minimum period before they could be posted. The ECJ addressed this in a subsequent 2006 ruling, Case C-244/04. The court clarified that member states are not allowed to require a minimum prior employment history before a worker can be posted under the Vander Elst regime. This means an employer can hire a non-EU worker and deploy them to another EU country almost immediately, provided all other legal conditions are met.
