Mia, from what I've read from this post and your post on the Answers forum it seems you were taken in by an illegal visa scheme. If you do not work for your sponsor - and you have said he is an unknown "Qatari police" - and you were working for someone else then you were sold an illegal visa. It seems your previous employer knows this and is willing to take advantage of you. All I can say is I'm glad you posted this so that everyone can see what a mess an illegal visa is and wish you the best.
