As said before you need a Bahamians partner in a % , but missed in this is that all jobs must first be offered to a Bahamian and if no one fills it you may apply for a work permit and wait and wait unless you connections.
Bahamas like some small countries are run by corrupt politicians-gee sounds like home!
Folks go every day with pipe dreams to live the life on some tropical island and well it just don't work that way!Been going to the Islands for 25 years and have had the same crazy ideas,Know locals and have friends on the island some great folks,the sad thing the islands are mostly in poverty, crime is high,drugs,corruption ect,,health care is mostly non existent so plan to fly to main land USA for health care,food cost are nut's and plan to live on fish,conch and chicken and its not bad!
Housing yes you can get some shack to rent as housing is high in good areas and other areas are just unsafe,
Most folks doing business are repatriates and give up all there rights, and taking money out of the country is a tricky thing to as the government dose not like this.
I hear there are some country's developing that welcome a skilled workforce-but for how long?
BTW the Bahamas has a book you can buy that tells all about the rules and regs, taxes,fees import and exports,partnerships,buying property's and so on.
