3 years ago, my husband also have to wait for 3 months to get his working visa in Qatar. But Alhamdulillah he got it.

There is a quota given for each nationality. So, your future company can only be able to apply for your visa, once there is vacant visa, means other pakistani cancel his visa, means his quota number is vacant, then your company will process.

Just pray for the best, that one of your compatriot getting a better job out of qatar, so you can come to re-fill his place.
