I'm currently staying in a guesthouse in Bangkok. I'm here as a tourist. At some point, I might have to go to the immigration office to get an extension. I'm here on a 30 day visa exempt stamp. My question is this : do I have to worry about TM 30? I will only be staying in Bangkok.
TLDR : Answer Summary
If you are staying in Bangkok on a 30-day visa exemption stamp, you need to ensure that your guesthouse files a TM30. This is important for obtaining an extension at the immigration office. It's advisable to talk to your guesthouse management to confirm that this has been done to avoid any fines.
