Well that is one persons viewpoint......
Visa is the first obstacle I would say.
As for the flying, well instructors do not earn much, but is that any different to the UK?
The difference here must be the amount of flying. More schools than you could shake a stick at. Weather is generally better, so more flying. Alternatively, the weather can be worse (MN), so there is true experience of IMC and IFR.
Not sure what is needed, but the license conversion isn't going to be tough, as long as the real flying is up to scratch.
As usual, watch out for the cowboy outfits, fly lots, and get in some real experience.
Good Luck.
