Hi easy,
Some command time would make you employable by
VB, but neither they nor any of the large regional Turbo-prop opertors take DECs, so you'd be going back to the RHS.
No, there is no discrimination because of where you come from. The only problem is you won't "Fit the mould" with regards experience and background, simply because the system is so much different where you come from.
I've no crystal ball, but my feeling is expantion will be incremental rather than explosive for the next little while.
Hope this helps. BTW where are you based?
