I see you have 3 very clear options and a one very black.
-go for Spanish ATC, when the "convocatorias" come out, they are very well paid. When?? who knows...it's Spain afterall. And I mean real ATC not the new small airport controllers.
-apply to US ATC. Not bad, you sleep home every night. Pay just got better.
-Fly in the US. Looks like its picking up again.
But forget about flying in Spain, the market is rotten. You will have to pay for your rating and it's pretty much impossible to land a job.
Good luck either way.
