I've read people saying that expats have trouble using efile because the efile system does not accept foreign addresses.
In order to get around this, is it OK to purchase a mail forwarding US address--one of those services where they scan your mail and you can read it online, and then put this addresses into the efile?
If not, is it OK to use either my US home address and a mailbox address that is tied to my US bank account?
