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

For the purposes of the investigation, it is obviously important to provide the organisation or individuals looking into your file with as much information and evidence as possible. It is also important that you remain available so that they can ask any questions if anything is unclear. 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.
