Friend had a weird situation at Phang-nga immigration yesterday. Said covid extensions weren’t a thing anymore and was given 30 days only (even though they had already had their 30 day standard extension). Looking at the stamp it seems like a standard covid extension stamp, but for only 30 days. Same happened to a friend in Bangkok, but another friend who went at the same time in Bangkok got 60 days…
This happened to me twice before, it's a bit annoying! They've been able to sort mine out at the local immigration office in the past, but that was a while ago. The second time I caught it before I left the booth at the airport.
