Hi there,
Dont want to sound rude !! but there are a few threads that you can read on the question that you have put out to everyone.
To make it simple, if you not from the country or a resident for a few years, eg: 6 to 8, then there is no point in moving cause you will have a long wait till you can go op's on a airline or even private on a local reg. a/c.
Brazil - you need to know portuguese, be a resident, and if you are not from a country of portuguese origin, eg: portuguese colonies, and you are not married to a brazilian, and a few more things, Then there is not a chance. Well there is, but you will have to wait a few years. You can do some hard core research on this, but the light is still far down the tunel.
Other Latin American countries go the same path with x-pats and non passport holders.
Unless, you get a job offer from a local company (or the local goverments change the regulations) the chances are 1/100. Although you know that there is a growth in the airlines, and the need for pilots is high, this is the facts that you will face.
I hope that i have answered you question, once again there are many threads on these matters that you can read up.
Safe Landings.
