It took me 2 weeks. I phoned the FAA about 5 minutes after I faxed the forms to them to check they had them, The nice lady at the other end said yes and she would request the details from the CAA while I was on the phone and promptly sent a fax while I waited.. All of 5 minutes. I was then told that all that was needed was for the CAA to do there bit and return the forms.. I waited 10 days for that!!!!!! I chased the CAA up and they finally told me they had sent the forms back to the FAA, within 24 hours I had a call from the FAA to say it was complete and I could collect the Temporary cert from the FISDO office on my arrival!!
You make your own mind up who's dragging there heals! Although I have to say I was suprised how easily and quickly the FAA issued the license, I guess they could just be very efficient, who knows...
