unfortunately the answer is yes. and more unfortunate you are coz the wait period is not 2 but 3 months.

there are 3 ways to get ur wife back.

1) apply for her RP. for that you need to have 6 month bank statement, marriage certificate etc etc etc.
2) get some wasta and try to apply for one more visit. the 3 month rule is not mandatory for everyone. if you got good wasta, they can help you.
3) approach some visa agents. they can help you get the visit visa but will charges you huge sums (upto 1500 QAR).

any other comments welcome.
