I left with my US bank a residential address in Argentina and a different mailing address in the US. For the purpose of providing a mailing address, I use the OCASA box of a friend of mine in the United States but I never include the word "box" in the mailing address, just in case. I get all the forms and statements online and if I need to receive a credit or debit card, sometimes it takes too long or they get lost so I call the bank and ask them to send it to me to Argentina via UPS or via Courier with a tracking number, that way I receive it safely.
