What documents do I need to provide for a DTV application as a self-employed business owner in Thailand?

An individual seeking a DTV visa in Thailand, who owns a trading business without clients, is uncertain about the documentation required for their application. The conversation suggests that a letter of explanation, tax returns (like Schedule C), and business registration documents may suffice. It's emphasized that working remotely for clients based in Thailand is not permitted. Responses indicate that requirements may vary by embassy, and it's advisable to reach out to them directly for specific guidance. Users also discuss the definition of self-employment and whether it qualifies as a legitimate business.
