Over here the medical check is done based on blood and chest X-ray, if your scaring is negligible then you have a good chance of getting away with it, if not and it is noticed then you can be rejected, although maybe if you explain it to them with all the documents you have they will make an exception.

One thing here in qatar is that all the Good doctors have been kicked out of the Government Medical Service. So you are left with all the crappy ones who get jobs cause they know arabic or they got it through qatarization and the Asian nurses here know better. You do not have a choice as far as expertise goes so might have a little trouble trying to get your point across since but Hey never say die....

Good luck to you, make sure you get reports certifying that you are completely free of the condition and it is certified by acceptable health authorities in your country. Get a certified doctor list from the Qatar Embassy in you country, and get it certified by them....
