Hi, I'm moving from Bangkok to Chiang Mai on Dec.29. Is it really true that I must notify Immigration within 24 hours?!? That seems extreme.
TLDR : Answer Summary
Yes, it is true that you must notify Immigration within 24 hours of moving. This requirement is part of the Immigration law established in 1975. Other individuals have confirmed that failing to do so can lead to fines. However, it is now easier to report a change of address since landlords can do it online in a matter of minutes. If you move on a weekend, you can report to Immigration the following business day.
