visa validity 17/11 means you will have to enter Qatar before 17/11/2013, after that you wont be able to cross the immigration. But you will have to enter at least a month back as you will be going for medical test and finger prints. For family usually the process can be completed within a month. once your medical and other issues are over, then only you will get one year visa. If rejected, you will have to go back again. Wish you best of luck
