Most Europeans applyin for RHS jobs via the middlemen are sent off to Asia so I understand as its hard for the companies in the US to justify to the Immigration service why they are using non-Americans.
There are a number of providers such as Eagle Jet, a search on here under 'scum' will bring up the rest
2nd - I'm not sure if the requirements out here for the TR are the same as in Europe, maybe someone can enlighten us. But the article I posted seemed to allude that there was a flight portion. Maybe the JAA cost covers everything and the US is itemised.
Mate, I'm still 4 months away from doing the TR, all I can advise is do your homework, research on here extensively, take everything with a pinch of salt and go with what your brain tells you, avoid emotion.
