The main problem for someone with a US ATPL is that it isn't an ICAO license. It might be worth thinking about getting a Canadian ATPL, since that is an ICAO license, as a first step to finding work outside the narrow boundaries of the USA and its affiliates.
Then the next problem will be having the hours and experience for anything but the bottom-level jobs. My experience has been coming up a day late and a dollar short on that, somehow, but I still have managed some sort of always being in work, at least.
Have a look in the back pages of Flight International for a basic idea of what is on offer, if anything. Things seem to be in the doldrums right now, sad to say.
I wouldn't worry too much about being desperate to leave the States. You want out, you can get out. The problem will come later when you go looking for somewhere to go back to. Then you find out that, `You can never go home again.´
Good luck, and don't mind the jeers from the Yahoos.
