I have a tm30 for my place of residence in Chiang Mai. I stayed 1 night in Mae Hong Son last week. Is my tm30 still valid? Is it possible to check at immigration prior to trying to use it to apply for a covid extension? Thanks in advance
TLDR : Answer Summary
The TM30 form is used to inform the Thai immigration of your residence. After staying overnight in another province, you need to ensure that a new TM30 is submitted upon your return to Chiang Mai. One user reported that they were able to have their TM30 updated at immigration without any charge when they informed them of their recent stay in Mae Hong Son.
