For every thing you need your Qatar ID card. To obtain a Q-ID card, you must go through your medical, finger print, visa / RP stamping etc., all these your company should take care.
Once you get your ID card, take NOC letter of sponsor for driving licence procedures.
After RP stamping, speak to your sponsor about bringing your family, get his NOC papers, then you can apply for 6 months visit visa. If you meet the deadly criterias set for Family RP, you can go ahead but for every thing you must go through SPONSOR ( except to go for toilet & bathing ) DONT WORRY, BE HAPPY, GOD BLESS U.
