Daniel, We have moved here from Austin and are legally able to work. Since moving here we have gotten at least half a dozen job offers. Although there are plenty of Belizeans out of work, the reality is sometimes employers prefer to hire a gringo/gringa for certain jobs. Gringos who want to come down here and become divemasters, for example, may feel a little (or a lot) of resentment. The fact is, if you want to work here and don't mind making little money, I'm sure you can find a job. Whats encouraged is for you to come here, open a business, and hire Belizeans. This island is still lacking in some areas and the right businesses can only improve island life.
When you come, remember to bring lots of money with you because it is more expensive than you might think to live here.
Good Luck to you, and Welcome
