Once again you are up against the same problem as others who have decided to move abroad. How are you going to get the legal right to stay there? You cannot, for instance, decide you want to move to Barbados and just show up and settle. You must apply for residency and prove sufficient income to live, by their definition of sufficient. In many countries you are required to invest a minimum amount of money, or to start a business and employ locals.

Howver, you can move to Puerto Rico or the US Virgin Islands, as they are US territories. It wouldn't be any more difficult legally than moving to Hawaii would have been back in the fifties. They are US Territories.
