A 22 year old student who just graduated will join a private company in Belgium for a one month unpaid internship/training. The company did not provide any information or help regarding the visa he needs to apply for. Instead they said "Please check what is feasible on your side" (visa, accommodation etc.).
Could it be that he just needs to apply for a tourist visa, and join them casually?
Any guidance or info before he gets back to the company asking for info? I was expecting them to apply for a work permit for him (http://werk-economie-emploi.brussels/en/work-permit-intern).
