Shygirl,

I think you need to consider a few points

1) as mentioned by Gumbo, you need to check with your sponsor.
2) Checked out your profile, your disadvantage is age & job title
3) As to what i understand, only female govt employees can sponsor family members into qatar.
4) Your next option will be Visit visa thru Qatar Airways, after you arrive in Qatar.

All the best, please post your comments when you do arrive or u need any more information, or you have information to share.

Cheers

Angelo
