I’ve read the conversations and I believe there is a misconception here. I’ve owned 2 copies in Thailand legally since 1992 and always had an immigration lawyer. I never had or needed a work permit simply because unless you are being paid a salary in Thailand you do not need a work permit. My salary was only paid by the US company and zero payment by the Thai Companies. If you earn a salary and you are going to be paid in Thailand by a Thai company you must have a work permit however being paid by a foreign company for what you do in Thailand does not.
