If I have a visitor visa to Belgium and I find an employer so can I change my status and get work permit?

You don't "change" it... work visas are very difficult to get for a reason... you will have to make a new application... and wait.

For most countries, you cannot change "status" to employment visa if you enter the country as a tourist. Procedures always take long time and your visitor's visa will expire before the approval date.

Have the employer handles paperwork while you return to your home country as you will need to apply for employment visa and must verify your eligibility with the consul at the interview. Don't overstay.. ever!

kanoshy does not find this helpful : he didn't specify where to make this application during the visit or must be abroad

You are rather stupid... are't you? You can't follow directions... and you can't follow rules of this site or anyplace else can you. And WHY do you think you are special enough they would bend the rules for you? Go back to wherever you came from. THink you are the only one to dream up the falacy that since you are already there they HAVE to give it to you? Dream on... they are wise to that (and far smarter than you) and make you go home and apply from your home country as a result.

Because even a simpleton knows it takes time and they won't do it they way YOU want... and of course were too stupid to mention on your original post.

YOU broke the rules about giving a not helpful because MY statement was 100% factual... just because you didn't have enough brain cells to provide all the information in your first post... you have to get RUDE and break rules. Well I hope they catch you, throw you in jail, and deport you, since YOU apparently have all the answers.

Just so you know... while YOU may have the ability to read other peoples minds... the rest of us don't. We rely on the information YOU provide.
