Countries I'm researching: Panama, Chile, Singapore, Hong Kong, Vietnam. All have ups and downs. Read the works of Doug Casey, Andrew Henderson (Nomad Capitalist), and Simon Black (sovereignman.com) for information on how to get offshore corporations and bank accounts so you can do business overseas, and second passports so you can optionally be unaffiliated with the US and don't have to worry about having your passport revoked by the US.
