well in order for you to get nurse license in Qatar, you should ask first your company letter; stating that you are a qualified nurse from whatever country you from. then show all your pertinent docs i.e school records, nurse license and you have to take ILS training which is necessary to get this NHA license, then medical test conducted in medical commission. It's a long process specially if you are working from distant location.. anyway just go and see the NHA office to get the complete info.
