I am currently in Siem Reap and plan to travel to Bangkok next. It seems we will be travelling through the Poipet/Aranyaprathet border. Is it possible to get Visa Exempt entry as a UK citizen at this land border (this will be my second visa exempt entry this year).
I have looked online and there are mixed answers.
TLDR : Answer Summary
A UK citizen can enter Thailand visa exempt at the Poipet border, even for a second entry within the same calendar year. However, travelers should be prepared to present the "three proofs": proof of onward travel, proof of accommodation, and proof of sufficient funds (20,000 THB). There's always a slight chance of additional scrutiny at this border, but many have successfully crossed under similar circumstances.
