Where should I go for my tourist visa extension, MTT or Chaeng Watthana, and is an appointment necessary?

And this is why terminology is SO very important people. :/

@William *****

there is no "original 30 day tourist visa" So you are here on what's known as a visa exempt entry <- it means you showed up with NO visa in your passport and were stamped in for FREE for 30 days? Right? 　

In that case you still go to MTT just like you have been at Counter K. and remember they are only letting 300 people a day show up SO go on the 27th OR on the 29th <- you won't be fined for overstay because the office was closed the date your stamp expired

@Benjamin *****

Could he still go to immigration on the 29th if his extension expires on the 28th because it's closed/holiday on that day? Guess you can still do this with any extenstion including an existing COVID one; might be busy on the Tuesday

Correct i was just in chaengwattana and make my visa covid extension. I'm arrived with 60 days tourist

What is a "tourist visa"? If this is a 45 day visa exempt stamp, then you would go to MTT. They only accept 300 people in a day. If this is a 60 day tourist visa, you would go to Chaeang Watthana 3 business days before your current stamp expires.

The appointment system is currently not working, and it's walk-in only service
