Okay...probably nil chances of a flying job in the USA at the moment.
Look at your alternatives. 600TT/300 on that filthy Jetstream. Your experience, with respect, is very limited and this means that you would have to stay for some years in Europe to even get close to a command or a jet job?
Now you have the opportunity to go to the USA during a recession. But their recession will end before Europe's has even got to the bottom. So there lies the main chance!
Thunder and lighteneing...go to the USA. Work as a hot dog boy, any trade,study and pass the US ATPL exams and be ready there, green card done, for the upturn. Oh, and while you are about it, become a naturalaised American.
Europe is a dead duck for a decade.
(You can let your JAA ATP lapse and renew it within, I thinkso, five years from expiry.)
