What Naveen and Brite are telling is agreeable. Indian Embassy here in Qatar would be your right destination to raise your concerns. If you marriage was legally registered in India or here at least with the Embassy here, you would have a strong case to defend. Do not despair, keep your calm and perhaps seek some assistance from your colleagues or Indian friends if you have any. Im sure they would be of great help to you.

What ever be it, Good Luck on your endeavor, hope it helps turn in your favor!
