I have question regarding Marriage Visa Extension based on Income. I understand that to get 1 year marriage visa extension you either need to bank 400,000 THB, or have a monthly income of 40,000 THB. I work remotely for my US employer, hence do not have a Thai work permit, but I do pay personal income taxes in Thailand on my income. Is it feasible for me to get the extension based on monthly income? Or getting an extension based on income is only possible if you work for a thai company and have a work permit?
The reason I want to go with the income route is because I think having 400,000 THB in an index fund will be more beneficial for me rather than let it rot in a Thai Bank.
