I am currently living in Chiang Mai and have to deal with the CM Immigration office. If I were to move to a different region in Thailand, say Bangkok or Phuket, what documents do I need to file to change offices? Would it be a TM28 for a permanent change of address or some other documents? Would they have to be filed in CM or the new region? Thanks
TLDR : Answer Summary
When moving to a different region in Thailand, such as from Chiang Mai to Bangkok or Phuket, you will need to file a TM28 for a permanent change of address and also ensure that your new property owner files a TM30 with the local immigration office. The TM30 must be reported within 24 hours of moving, and it is important to consult the new immigration office for any specific requirements.
