I actually think it would be a good idea to come to the US as a Flight Instructor - as long as you do it legally.
We are still looking at an instructor shortage in the US. Considering the regionals are going to start hireing again arround 3rd quarter 2002 it would be safe to assume that many american instructors will jump off to join them.
The time is right to broaden your horizons and if you then have FAA and JAA ratings you will be very marketable worldwide.
Good luck!
