Hi. I returned to Thailand today, and I’m planning to go update my TM30 tomorrow... I know it’s a bank holiday but last October, I got fined for not reporting within 24 hours and the officer at the time said the TM30 office at Chiang Mai immigration (right side of the building and up to the 3rd floor) is open every day, including Sunday, 8:30-4:30. Just checking to see if anyone has gone on a holiday to find it closed, etc. thank you!
