I live in the U.S., but I'm travelling all the time and I really don't offer any physical goods, no inventory etc. So there is no shipping involved, etc. However, I am creating sites here in the USA at the moment. Should I register my business here in the USA, or should I look into other countries like costa rica, panama or the virgin islands? What are the advantages of registering my business over there? Any experiences? Thanks! any advice will be greatly appreciated.
