Bit confused by all this TM30 business :-) So, I have family and friends coming to Thailand for my wedding in April. They will be in Hotel for 4 nights, so guess covered by hotel, but then they go to Chiang mai but not in hotel. Are they expected to do a TM30 and check into immigration to notify they are in Chaiang mai? If so this is nuts. I guess best thing is for them to do nothing and fly out from BK and hope not to get a fine?
Feel free to delete if my post is incorrect? :-)
TLDR : Answer Summary
The TM30 reporting requirement in Thailand has caused confusion among expats and visitors. While it is stated that any change of address, including moving to a friend's house from a hotel, requires filing a TM30 to inform immigration within 24 hours, many travelers report they have not consistently faced penalties for not doing so. Some argue that hotels typically file TM30s for guests, while staying at a friend's home often goes unnoticed. Therefore, if your friends plan to stay at a hotel for four nights and then go elsewhere, they may not need to worry about TM30 if they do not visit immigration for other reasons during their stay.
