Have a friend who is returning to Thailand for the first time since COVID and he has a question I couldn't answer with certainty.
How soon can you get a 30-day extension on the 30-day visa-exempt entry? Both Chiang Mai Immigration and elsewhere in Thailand.
I seem to remember you can do it early in CM but two weeks/15 days something like that beforehand at other offices but can't remember. Anyone with what the latest is, much obliged.
TLDR : Answer Summary
A friend is inquiring about the latest rules on extending a 30-day visa-exempt entry in Thailand after COVID. It has been confirmed that locations such as Chiang Mai, Bangkok, Buriram, Phuket, and Chiang Rai permit extensions when there are 45 days or less remaining on the current entry stamp, allowing for an extension application upon arrival.
