As long as you are a post graduate, you can apply for the PhD degree. Ofcourse, your percentage in PG degree has to be higher. Now, it may take anywhere between 2-10 years to complete your PhD for a simple reason that you will have to select your subject and prepare thesis on the same. This thesis has to be unique, with support from lot of research. I personally think that it will take 3 years when you are 100% on the studies. Good luck with your PhD. As in Qatar, you can approach Qatar University, or CNA-Q, or other colleges to confirm if they offer PhD here!
