U can go Human Rights Committee, but really it is west of time sometime . Because they will send request to the company if company not answer they will send again and again, then if ur not follow up they will just let go slow. In this moment u need to go to the company ur wife work for and ask them to take out black list otherwise no one can help u. In Human Rights Committee u need to write all story about what happen in this company and what is the reason ur wife left the company if u can get marriage her in Qatar.
