I have a 1 year O-A visa expires 31/10/22. Have been in/out of thailand 3 times this year, every time I get stamped for 12 months stay from date of entry. I arrived this week and they would only stamp me up to the end of my visa, end Oct 22. Had a bit of an argument with the officials about it - showed them previous entries etc, but they were adamant and wouldn't change it.

Anyone have similar visa and can advise which is correct?

Thanks
