Hi Rick,
Thanks for this feedback. In another thread "http://www.qatarliving.com/answers/travel-and-holiday/travel-ban" I found that, even if there is no travel ban and you get an exit permit, there could be something called "Travel Hold", which I presume is different than the normal travel ban.

I am a bit nervous as I would be travelling with my family and if some problem happens in the airport immigration, then I will be nowhere.

Thenks for your kind feedback,
