I was able to just show my Canadian driver's license and get the Qatari license (with the permit letter from her/your employer and usually a letter from hubby) Took 20 minutes.

However, I understand that if you have a US license you can no longer follow the above (which was the same as for Canadians in the past) - I don't think it has changed, most of my colleagues who have arrived in the last 6 months haven't mentioned having to take a test or lessons.

Best you can do is go to the Traffic dept with your paperwork and see what they say
