How to bring your wife to Qatar on family visa?

1) Check with your Mandoob or Immigration if your
salary & position would qualify you to sponsor

2) Check with the Immigration for the documentation
requirements & fees

If your documents are complete, you can apply her for
a visit visa, 1 mo. (easier & faster, 3 days approval). Then, extend her visit visa for 5 mos. when she is here in Qatar. Later, apply for her family visa but before the expiration of the extended visit visa.

Also check, the documents for a visit visa. More or less, these are the same with family visa requirements.
