medical certificate for belgium work permit

That is a very specific question and I doubt you will find someone to answer that. 

Not many people from this part of the world get work permits for Europe and the few that do, are usually transfers from their companies to overseas offices with process being managed by the employer.

Why don't you ask your future employer?   but any recognized large hospital would be acceptable I assume.

Hello xtang..thanks for the response..i finally got the response from the embassy and you are right. big hospitals like doha clinic ,al ahli do this. I got the form from the vfs qatar center.
