I would suggest that you probably want to incorporate in a company that doesn't tax worldwide income and not the United States. If you plan on living in Thailand forever, then you might find that incorporating where you live results in the most sane result for most people. I would not suggest the USA if you don't have any strong ties to the United States. It could just result in your being taxed here unnecessarily or being considered having close ties to the USA if you apply for a visa.
