Just to add... You will need to get an FAA PPL based on your JAA PPL. This will involve a fee that you send the CAA authorising them to release your details to the FAA. Takes a few weeks to arrange, especially given that our postal system is on holiday at the moment.
You then have to book in with a local FSDO in the US and get a temporary FAA license and will have to do a Bi-annual review with an instructor when you get there... Allow at least 2-3 days to sort all this out, especially if you arrive on a Friday night as they aren't open at the weekend. You'll get your shiny credit card license in the post about 6 weeks after you get back home.
There are loads of posts regarding this on here, easily searched... I think the user SocalApp is pretty hot on all this stuff as well, might be worth PM'ing him/her (!)

Reason: FSDO, not FISO!
