If I file a complaint, will I have to stay in Belgium?

For the research it is of course important to have as much information as possible and proof to the institution or persons who follow up your file. It is also important that you remain available so that they can ask you questions if things are unclear. So make sure they can reach you by telephone, WhatsApp, Facebook, etc.

If you have provided all the evidence and information necessary and ensure you can be reached, you do not need to stay in Belgium.
