So far I did not get a proper reply for my post in Qatar Living. To know this answer I went all the places and I spend a lot of time for this. Anyway I am very glad to help you in this case as i have already gone through this process.

As per this problem, you should reapply for a new visa. So pls do the following :

1. Go to Al Garafa Immigration Department and cancel your Wife’s old expired visa.

2. Go to Labor department and apply for a new visa as you did before(Full process with all necessary documents).

3. Once it is approved, get the VP number from Labor and go to Immigration department and print your Visa.

* You can pay Qr.500 and renew your visa only under one condition.

Example : Your Wife is out of Qatar more that 6 month and his Visa is still valid. Since her visa has been already expired when he is in your mother country, you should go again through all the process as you did before.

I hope that the explanation above is clear to you

regards,
