I found this thread through a search for how to get money out of the country.
An Argentine friend of mine needs to start moving money to a dollar-denominated bank account he's opening in a Caribbean country. He can change his pesos into dollars here if he needs to; I understand, from my discussions with him, that the real challenge is just finding a way to move money to the offshore bank. How would someone with a bank account outside Argentina actually move money to it? One factor that might complicate things slightly is that he lives in Mendoza, so I'm not sure if he has access to a cueva to do the transfer for him.
