No exams or flights tests required, just pay your money and they will turn up in the post.

Very funny
Not everyone took your hard grind route to a JAA licence !
There are an awful lot of pilots around with dual licences who did just that before the loopholes closed and they are usually the worst at damning FAA pilots and heralding their wonderful JAA licences!
Not referring to your good self but many I know of wished I had jumped through those loopholes myself now.
Anyway there should be a differences exam and that's it to convert nothing more is defensible
Intact I have it hot off the press that the FAA have taken over EASA and will now be the worldwide governing authority this was because EASA were determined to be a waste if space, and money and negative to the advancement of aviation in Europe!
