Without MERCOSUR passport or residence via spouse, pretty much forget it unless you got couple thousand hours and specialist skills (long lining, military etc.) for example for Chile. Some folks did mention contracts for old salts over there. Not for gringo newbies. I'd fancy flying rotary in Chile or Argentina, but the market is small and hoops to jump through. Brazil? hmm.
Sure, there is a demand for booming Pre-Sal oil exploration in Brazil, but, do you:
have 600ish rotary hours, fluent Portuguese, Brazilian passport?
As for other countries and stuff, well, you have to sober up a bit in your aspirations.
Also, you're not going to be 'commander' of anything else than training helicopters either as solo pilot or flight instructor after your CPL training. Doing JAA IR(H) may open doors to some co-joe job that'd be great chance (TWIN TIME), but you'd not be commander, so..
You've chosen tough career to get into and stay. But oh boy, isn't it great to buzz around in helicopter?
