Just wanted to give an update on my experience today. Arrived Jan 12th from the US visa exempt 30 days. Extended it another 30 days. And today received 60 day covid extention. Thai Immigration Bureau Muangthong Thani. Very busy and very chaotic. All I can say is make sure you double check everything you need. Good luck everyone.
