It's pretty easy to wire transfer money to any of the banks in Belize provided you can supply the multitude, and ever growing, list of information (a US legal requirement rather than Belizean).

Bear in mind it is always very easy to convert US$ to Bz$ - be that cash, Travellers Cheques, Money Orders or Cheques. It is very difficult to convert Bz$ to US$. We looked at opening a Belizean US$ account and part of the Central Bank (they control all foreign currency)terms is/were that if needed they can seize(my word not theirs) US$ funds in extreme cases of shortage in return for BZ$. I was told this had never happened but it was enough for me to keep my US$ elsewhere.
