Thats because you are converting from FAA to JAA. It is easier to get your JAA in the U.S and then apply for FAA based on your JAA.
I got my JAA PPL in Florida. When i got home my local club where not pleased that i did not get my PPL with them and tried to make me do another skills test. I put my foot down and told them i will do a check ride and that is it, as I have a valid JAA PPL i don't see why they should want to make me do another skills test. Some clubs will try it on and others won't, you just need to stand up to them.
As i still fly in the U.S from time to time i applied to the FAA for an Airmans Certificate based on my JAA PPL. it cost a grand total of £38 which was payable to the CAA!! The FAA actualy gave me an FAA license which is valid as long as my JAA license is valid.
I was not asked to any exams or test flights, just for a few signatures.
