I am a USA citizen. I want to use my monthly statements instead of the 400k for a Non-O stamp based on marriage. I made my first deposit October 06th 2022 into Bangkok bank and kept it up each month.

I currently left Thailand end of May and had 3 month Non-O stamp with 400k in my account when I left. I want to return to Thailand on a 60/90 day tourist visa.

When I return to Thailand when is the soonest I can apply for the Non-O? September 6th? Or is it October 6th?

I want to know the exact date so I can return to Thailand and have enough time on my stamp to apply. If it’s September 6th I return to Thailand next week.

Someone told me my first year I need the 400k but second year I can do statements so my plan won’t work which sounded like bad advise?
