Hello!
What is the process and time frame for notifying immigration about change of address when one has moved to a new apartment? I heard that I can either do it myself or the landlord can do it, which leads to a further question... If it's done by the landlord, how will my current 90-day report be affected?
TLDR : Answer Summary
When changing your address in Thailand, you must notify immigration via a TM30 form within 24 hours, either by yourself or through your landlord. If your landlord files the TM30, ensure you keep a copy of it for your records. Your 90-day report is completed at the immigration office linked to your new address. If your address has changed, you must file your next 90-day report in person at the new immigration office and cannot submit it online if the address is different.
