I've carefully checked: in 2024 I stayed less than 6 months in Thailand (175 days). I made 1 border run in Nong Khai and stayed 10 days in Hong Kong. The border run was the first in many years. And in 2025 I came in February 18 with a tourist visa. So, if they refuse me at Suvarnabhumi or Don Mueang, nobody is going to be accepted.
