Siddh, as far as driving licenses are concerned, an international driving license is usually only valid as long as you are not a resident, as far as i know. Once you get a residence permit you are expected to obtain a local license. I am not familiar with qatari law that well so i cant tell you whether an indian license can be converted into a qatari one, if not, youll need to take a new test.
