I was originally going to train in the UK, however, a friend (who lives in Sarasota) said it might be worth my looking into how much it would cost to learn in the US. As you said, I didn't really do much homework - I just contacted the aforementioned helicopter school, they said they could train me, and all I would need to apply for, is permission from the TSA, which I did.
STOP!!!!!
You need to stop what you are doing - and do a lot more research otherwise you could waste tens of thousands of dollars!
I find it incredible you just booked without knowing about schools or licensing.
Slow down and do your research!
