I just received a free COVID extension stamp until 30 November at Udon Immigration, so not December like some others have received elsewhere apparently. And they also gave me a little yellow reminder paper that says "4 November" and they said if I'm going to request a December extension then I'm only allowed to request on 4 November at their office, not any other day otherwise it will not be accepted... they also said I will need an additional letter from the US Embassy again... so yah, definitely not what I've been hearing from other expats... maybe Udon just sucks now! 🥴
