The single permit, explained: one application, one document, three EU variations

Before 2011, a non-EU worker coming into the European Union often had to clear two separate files: one for the right to work and one for the right to live in the country. The EU Single Permit Directive (2011/98/EU) collapsed that into one application procedure and one combined document. File once, get a single card that carries both the work authorisation and the residence right. That is the rule on paper across most of the bloc. The way each member state runs it is where employers lose time, and Belgium is the clearest example of why one directive does not mean one process.

What the directive actually changed

The directive did two practical things. It created a single application procedure, so an employer or worker submits one file instead of two, and it created a single combined permit, one document that proves both the right to reside and the right to work for the named employer. It also attached a common floor of rights. Holders get equal treatment with nationals in pay and working conditions, along with certain social benefits, which means a Nepali welder on a single permit in a given country is owed the same hourly rate and the same safety standards as a local doing the same job.

The directive also set a ceiling on how long the state can take. Many national transpositions adopted a maximum decision period of four months from a complete application. That number is a legal limit, not a promise of speed. In practice the clock only starts once the file is genuinely complete, and a missing labour-market document can keep the application out of that window for weeks.

Belgium: one card, two levels of government

Belgium is the case that breaks the tidy "one application" picture, and it does so for a structural reason. In Belgium the labour-market authorisation, the part that decides whether a non-EU worker may take the job, is a regional competence. The residence element is federal. So the single permit, the permis unique or gecombineerde vergunning, is processed at two levels of government at once even though the worker ends up holding a single card.

That regional split is the named complication. Flanders, Wallonia, and the Brussels-Capital Region each run their own labour-market rules and their own processing. A warehouse role in Antwerp is assessed under Flemish rules; the same role across the regional border in Wallonia is assessed by the Walloon authority under its own list and its own criteria. The federal Immigration Office handles the residence side once the region has cleared the work side, then the combined permit is issued. An employer who assumes Belgium has one national queue is planning against a map that does not exist. The first question for a Belgian hire is not "what does Belgium require" but "which region is the workplace in."

The same directive, different national names

Because each member state transposed the directive into its own law, the single permit travels under different names and different administering bodies. The document is the same idea; the label and the authority change at every border.

• In the Netherlands it is the GVVA, the combined residence and work permit, and the recognised-sponsor status of the employer largely decides who can be hired at all. The mechanics of that are in the Dutch GVVA single permit.
• In Czechia it is the zamestnanecka karta, the Employee Card, which carries the same dual authorisation but gates the hire on a public vacancy register that the job must sit on first. The detail is in the Czech Employee Card.
• In Croatia it is the jedinstvena dozvola, the single permit our Zagreb desk works with most often for construction and tourism roles.
• In Belgium it is the single permit or permis unique, split by region as above.

Same directive, four documents, four authorities. The procurement lesson is that "we hold a single permit in country A" tells a hiring manager almost nothing about what country B will ask for.

The recast: what changes for workers

In 2024 the EU adopted a recast of the single permit directive. It keeps the one-application, one-document structure and strengthens the worker side. The headline change is a clearer right to change employer during the permit's validity, rather than being locked to the single employer named at issue, subject to conditions each member state sets. The recast comes with a transposition window during which member states write it into national law, and until each state has done so the older national rules still govern day to day. Treat the recast as a direction of travel rather than a rule you can rely on in every corridor today, and confirm where a given country stands before you build a plan on the right to switch employers.

The failure mode that costs weeks

Here is the concrete way a single permit goes wrong in Belgium. An employer in Flanders has a complete federal residence file ready and assumes that is the application. It is not. The labour-market authorisation from the Flemish region is the gating half, and if the role does not meet the regional criteria or the regional file is incomplete, the Flemish authority refuses or returns the labour-market part. The federal residence side cannot carry the application on its own, so the combined permit is not issued. The worker stays out of the country and the start date slips. The employer often discovers the problem only after booking flights against a date that was never real. One file, two authorities, and the slower of the two sets the timeline. Build backwards from the regional labour-market decision, not from the federal residence paperwork.

Processing times across these corridors vary more than the shared directive suggests, and the corridor-by-corridor timeline is the quickest way to see where Belgium, the Netherlands, and Czechia actually land against each other.
