To Tugpilotsmiffy :- I don't know wether you are a looking for a fixed wing or rotary school, but if you are after a rotary school then try this link:-

These guys will sort all the paperwork out for you etc....
I will also refer you to the previous thread by decimal.
I know not how much flying you have done previosly, or wether you have any flying training, but read his thread and you may get some idea, that if you have training already, then obtaining a J-1 visa, may prove a bit of a headache?
Somehow, i just get the feeling that after 9/11, the US has become a little sensitive....Can't possibly understand why
Good luck with your search and don't give up
