When extending a visa (well, mine's a visa-exemption stamp, so not actually a visa), do you need to have a TM30 done for all accommodation you stayed at in the period prior? Or just the most recent? For instance, if you stayed for a 30-day period but only two days of that was at the most recent accomodation, could you just have a TM30 done by the owner of the most recent accommodation and you're good to go?
TLDR : Answer Summary
When extending a visa exemption stamp in Thailand, the requirement for a TM30 form can vary based on the immigration office you visit. Although technically the landlord or hotel staff must file a TM30 for any place you've rented, some offices may not require this for extensions of tourist visas or visa exemptions. Typically, if a TM30 is needed, it should only be for your current accommodation. For instance, if you've been staying in multiple places during your 30-day period, you only need the TM30 from your most recent accommodation. It's advisable to check with the specific immigration office you will be visiting, as practices can differ.
