It is difficult, though not by any means impossible, to obtain living and working rights in the USA or EU for an alien. To find out how, you need to contact the embassies of the USA and any EU country in your own country. There may well be websites out there which will promise to arrange these things for you; many of them are scams, and I will not permit any such links on this forum (you might like to note that, strictly speaking, no links whatsoever are allowed on Pprune. I take a more pragmatic approach...).
