@John ********
being that you are on a type O extension based on Thai wife you can work, and get a work permit, by starting your own business in partnership with your wife. By doing this you cut in half the amount of registered capital needed in the business to just bt1million, and the number of Thai employees to just two, with one of them being a licensed Thai accountant, that can be part time. With this business, and your work permit, making at least bt40,000 a month, and paying your Thai income tax for three years, plus other requirements, you will be eligible to apply for Thai permanent residency, or directly to Thai citizenship. If you don't work then none of the other requirements matter. This is just something to think about if you plan on living here.
