No worries. Just go thru the airport. They will direct you to overstay counter in BKK. If only one day, you will not likely be fined the 500 baht but receive a red overstay stamp
not really correct on the financial comparison as DTV is multi entry. If you want equivalent on retirement extensions, you need to add on 3800 baht per year also.
you have absolutely no clue what you are talking about. I’m a little embarrassed for you to be honest man. One becomes a 'legal' thai tax resident on day 181. Regardless of visa type.
