I got 30 days on arrival at Suvarnabhumi, I guess that's visa except then, and not visa-on-arrival, I didn't know the diff. First time for me arrival on a 30 day stamp like this. Ubon Ratchathani immigration just offered me 30 days extension or Covid extension. I opted on 30 days as I'd like to apply for Covid extension next month.
PS: as I'm staying at a Pvt address in Ubon, immigration ask for my friend's ID Card and Tabien Ban.
Thanx Joe
