Pls explain me how i'll apply fir visit visa for my wife and my kid?
What are the needed documents?

Bcz Im working for company more then two years on work visa by company sponsor ship. Now I am willing to bring my wife for 6 months. And my basic salary is 2000 QR. But Im getting more then 2000 QR as a commission. But If i request a salary certificate form my company they will give me as 2000 QR per month.

So, Is it possible to get my wife to qatar for 3 months by showing this salary certificate....?
