Wow, Garrett, I am really surprised by such an aggressive response. Instead of asking me for proof, you outright declared me a liar. Considering how many years I've been a somewhat active member of multiple groups about Thailand that you are in, I'm surprised you would react to my post this way and not at least show the courtesy to ask me for more information. I'll take some time to look for the proof for you, but I must call you out for reacting this way.
Yes, the 45 day visa exempt entry can be extended one time for 30 days, and potentially after that, you can extend repeatedly for the 60 day Covid extensions if they extend that program past the current late July end date.
Thank you both. I appreciate the clarification that the situation is different. It was not clear from the original post what visa he had. BTW, in my situation, I have a multi-entry Non-B, so it may differ from the OP's situation.
is that accurate if this was his first extension on his visa? Per Samui Immigration website, it says "The first application for extension of stay by the foreigner is equivalent to the notification of staying in the Kingdom over 90 days." Doesn't that mean the first 90 day report was considered done when the first extension was approved? I am in a similar situation where my original admitted to date was May 13th but I got a 60 day Covid extension granted on April 23rd good through July 12th so don't know if I actually have a 90 reporting requirement due now or not till July 12th.
The TM30 is not a proof of where you will be staying throughout your extension, as you seem to think. It is a form for the homeowner/hotel to inform immigration within 24 hours whenever a foreigner is staying somewhere. If you are staying at different places, each place should be reporting you via a TM30 when you arrive. In practice, immigration offices that want to see a TM30 for extensions just want to see that one has been filed for you before they grant the extension, and they have no way of knowing if you have been accurately reported every time you may have moved to stay in different places. It is not a report of where you will be staying in the future so if you are traveling around after getting the extension, that has nothing to do with the proof of filing TM30 you may need to show to get the extension. Also, as Benjamin stated, the TM30 is filed only after you arrive somewhere, so making a hotel booking doesn't mean they will file a TM30 for you until you actually check in.
