Hi,
My friend from Australia is trying to get a 30 day extension on his 30day visa exempt stamp at Cheangwattana. First extension on this stamp. He went and was told he needs a letter from embassy to get 30days, otherwise he will only get 7 days. This sounds very weird to me. Is it correct?
TLDR : Answer Summary
The consensus among commenters is that your friend from Australia should be able to obtain a 30-day extension on his first visa exempt stamp without needing a letter from the embassy. Some responses clarify that a letter is only required for a second extension on a 30-day visa exempt entry or a 60-day tourist visa that has already been extended. One commenter suggests that there may have been a misunderstanding during his initial visit, as he successfully received the 30-day extension on his next attempt.
