Hi, I am a UK citizen and I arrived in Thailand from Hanoi with 30 days tourist visa. Am I able to extend this for another 30 days? I have until 23rd November at the moment but I have a flight booked to Australia on 8th December. I am currently in Chiang Mai.
TLDR : Answer Summary
A UK citizen currently in Thailand with a 30-day tourist visa can extend their stay for an additional 30 days by visiting the nearest immigration office and paying a fee of 1,900 THB. The original admission date recorded in their passport will determine their eligibility for the extension, especially if they have previously used a re-entry permit.
