salary of QR 12,000/- is good enough to get your family aboard. its all the better to have 3 months bank statement, along with your application / sponsor's letter. you might be called-in for a face-to-face interview with 2-3 officers who sit at the labor office on c-ring road. don't forget to get your statements stamped from the bank. the banks here "strangely enough" charge QR 25/- for each months stamp. good luck.
