Hi there mrboli,
Well to be as short as possible, I have a Canadian CPL etc. and moved to Peru.
It was pretty complicated do to the fact that south american countries protect their own pilots.
Therefore they asked to me either live in the country with an
PR or to get married. After that i had to pass the hoel exam again CPL IFR and flight test.
It might be the same for other countries down here so make sure that you're ready to get a lot of paper work to get done.
Hopefully it helps you out, in case you got some other questions just let me know.
See ya
