I'm sorry first of all I think you should renegoiate your salary. An IT engineer only making 4000 QR a month??? First I should ask where you are from? I make that much in about 2 days of work. Anyway a buddy of mine got his wife and son a residency visa for about 3600 QR. Which isn't at all expensive especially if you want to be with your family. Well good luck with that. I hope all turns out well for you and your family.
