Its actually surprisingly difficult to open a bank account in Belize, even if you are investing a tidy sum of money. You will need an up to date written reference from two banks. You must also supply the address, phone number, fax and email address of your branches, which they will contact by one of those means. All 4 must be supplied, no email address for example = no account.
The good news is, if you do manage to get that account open, the interest on a savings account is a wonderful 7% compound interest, and that certainly makes it worth the effort!
