Just entered Thailand on my one year B Visa non immigrant multiple type but immigration officer stamped on my passport only 45 days stays as TR Visa and crossed on my visa as Last entry 18th April 2023 but my visa valid till December 21st 2023. He thought it was single entry tourist Visa.
I just seen after come out from the air port.
I supposed to get 90 days to stay ok same as before but now allowed me only 45 days and cross by a pen on my one year Visa.
Please advise me where and how to solve this issue?
