I have a marriage extension (from Jomtien) that expires in November 2024. I used the 400k deposit method to meet the financial requirement. I have done this a couple times already. For my next extension in November, I would like to change to the THB40,000 per month deposit from a foreign bank. Question: in this situation, how many months would the 40k monthly deposit need to be made in order to qualify for the monthly deposit method? Would it still need to be 12 months?
