Hi, I am currently in Da Nang, Vietnam where there is no Thai embassy and consulate. Would it be possible to get a visa exemption when I arrive at the airport in Bangkok and then purchase a 30 day visa extension on the same day from the airport? Any advice is welcome! (I hold a British passport btw). Thank you and happy new year! ๐
TLDR : Answer Summary
A British passport holder can arrive in Bangkok on a visa exemption for 30 days. However, they cannot purchase a 30-day visa extension at the airport. Extensions must be obtained at local immigration offices after arrival in Thailand.
