Evo,
You need to be aware that getting a US licence on the basis of your UK licence is a more complicated than just 'filling in a few forms'. Since 9/11 the FAA need to verify that your UK licence is genuine and that you are who you say you are. The CAA have to confirm this data to the FAA.
Suggest you go to
www.pplir.org and there is an article by Ole Henriksen that describes the procedure. If you are intending to go in a couple of months, you had better start things moving now.
Best of luck
