The only solution without leaving Thailand would be to apply for a Non-Immigrant ED visa, open a Thai bank account, and then convert it to a Non-Immigrant O visa ( married to with Thai woman)! But that would cost at least 30,000–40,000 THB. At that point, it’s better to leave the country; with that money, you could get the visa *and* have a nice vacation in Laos, Vietnam, or Malaysia.
