I pressume all requirments were provided before they (your family) got to Doha, so these are still filed in the Labour Department. You just have to secure that positive application # from that department and after 3 days you will be advised to collect a certain paper from them to continue the process to the immigration department...(mine took long process in the labour dept., I had to talk seriously to a man upstairs who only has decision for the said matters.)..good luck!
