If you are undocumented in Belgium and want to regularise your situation through work, you will in most cases need to return to your home country to file your single permit application. That is hard to hear — but it is also a procedure that works, when the file is well prepared.

The essentials
Two realities coexist: returning is often unavoidable, but it can also open a real door if your situation allows it.
To obtain a single permit (work permit + residence title), the procedure is in principle initiated from the country of origin. If you are in an irregular stay in Belgium, it is in most cases very difficult — or impossible — to regularise your situation without first returning to your home country.
The single permit can be granted in a near-automatic way when the file is complete and all conditions are met: an engaged employer, an eligible sector, documents in order. This is still an administrative decision, and there is always some uncertainty — but a solid file genuinely makes a difference.
An unprepared departure can complicate things: entry ban, pending procedure, missing documents. Before any departure, it is important to verify your exact situation so you do not unknowingly close a door.
In practice
The procedure and the chances vary depending on your exact situation. Here is what changes in practice.
This is the most common situation. To obtain a single permit, the procedure in principle requires you to be in your country of origin when the application is filed. Leaving is often a necessary step, not an abandonment.
This is an essential condition. Without a job offer, the procedure cannot begin. With an employer committed in an eligible sector, you have a concrete legal basis to start the process.
In that case, your chances of obtaining the permit are serious. The Belgian administration can grant the single permit in a near-automatic way when everything is in order. It is not an absolute guarantee, but it is not an impossible journey either.
You need to check very carefully whether an entry ban is attached to this decision. This can block or delay a legal return to Belgium — including through a work permit. This check must be done before any departure.
3 key steps
A well-prepared departure changes everything. Here are the three key points to check before making a decision.
Before leaving, make sure no measure would block your return. An order to leave the territory can sometimes come with an entry ban across the entire Schengen area.
The most common route is an employer ready to hire you in a sector eligible for the single permit. Without that, returning remains administratively possible, but there is no clear path to come back and work legally.
A solid file — with the right documents, the right steps and the right timelines — significantly increases the chances of a successful return. This is where LEXPAT Connect can help you find an employer matching your profile.
FAQ
Clear answers to questions that many people face alone before making a difficult decision.
In the vast majority of cases, yes. The single permit procedure is initiated from the country of origin or legal residence. If you are in an irregular stay in Belgium, it is generally very difficult to regularise your situation without going through that return. This is not a punishment — it is often the only legal path available.
Yes, your chances are serious. When all conditions are met — an engaged employer, an eligible sector, a complete file — the single permit can be granted in a near-automatic way. It remains an administrative decision, and there is never an absolute guarantee, but a solid file genuinely makes a difference.
The single permit procedure typically takes between 3 and 4 months once the complete file has been submitted. Timelines can vary depending on the region, the sector and the administration's workload. This is a difficult period, and it is important to prepare for it well before leaving.
Not necessarily. But you must check very carefully whether an entry ban is attached to that decision. That is the specific point that can block or delay a legal return — including through a work permit application. This check must happen before any departure.
