Stratocaster,
Not sure what experience you have had, but if you do everything by the rules, you can come over and do exactly what Lewy Boy wants to do.
When you come to the U.S.A. on one of these courses you need to be on a J-1 Visa. You will be able to complete all your F.A.A. Ratings and either instruct at Phoenix East or at any other Flight School in the U.S.A. until your J-1 Visa runs out. If you take a job at a flight school other than Phoenix East, you will need to keep in touch with Phoenix East at all times, since they are the ones sponsoring you while you are in the U.S.A., and give then monthly progress reports on your training (in this case amount and type of instruction given).
I currently have 7 instructors working for me who have J-1 Visas from other schools. They all trained for their F.A.A. Ratings after September 11th.
Happy Flying,
