as per my experienced, you should have with you complete documents (yours & your husband) for easy and fast processing e.g.6 months bank statement, salary cert. NOC, birth cert of your children, passport copy then obtain an application form from typing area (lady section) of the main immigration at Gharaffa. For further info, you can talk with the Qatari lady there at Bldg. 2 counter 15 (left side from entrance). She's very good and well in English
