Was at Chiang Mai immigration today for TM30 check in after spending a week in out of Thailand then 2 night in BKK. Immigration officer specifically told me no need to check in for TM30 if I’m coming from spending time in another province and returning home to the same address in Chiang Mai.
TLDR : Answer Summary
A recent experience at Chiang Mai immigration revealed that if you return to Chiang Mai from another province within Thailand, you do not need to check in for TM30, according to an immigration officer. However, this policy seems to vary across different locations, as others reported needing to submit TM30 notifications for any travel, even within the country. The discussion includes mixed experiences from places like Phuket and Krabi, highlighting inconsistencies in the enforcement of TM30 reporting.
