To the hive minds of the Thailand visa group:
I am a US citizen with a non-immigrant O-A visa with a length of stay 1 year. The Visa ends May 2024. Typically every time I enter Thailand I am admitted to stay 1 year from date of entry. But on my recent entry in November 2023 the stamp read admitted to May 2024 not November 2024. Why was I not admitted for 1 year from date of entry? thank you.
