About going to the US of A. It will cost you around 1500 US To do it, however, if you don't have the right to work there. Don't bother, it's a nightmare. I just got back from Florida, I planed to do the same as you, however, the licensing down there is a pain. And the jobs are only there if you "know someone" or your an American. See if you get a work visa there, you have to work for that one company, no other, and if you leave that company. And they call INS, and you're gone. Be careful. Get a FAR/AIM and make sure you do your homework before you buy your ticket. Also make sure you meet their CPL/IFR requirements. You need stupid stuff as far as certain multi flights and IFR requirments.
Be careful. Good luck.
