I posted the following in another thread, but I guess I'll post it here as well in case anyone is interested:
I went to MTT in Bangkok today (05 Jan 2022), got the 60-day extension until 25 Mar 2022, but they told me that this would be my last extension and that if I went in again, I would only get 7 more days. I entered Thailand in Feb 2020 and have been doing COVID extensions since then, and they said that part of the reason why I wouldn't get another extension is because of how long I've been here, but from what the woman at the counter said it sounded like they might be ending the COVID extensions generally or changing the system somehow, but this wasn't totally clear. I guess we'll see what the next announcement brings.
