Can I get a 30-day exempt stamp on arrival in Thailand from the UK and extend it for another 30 days?

Travelers from the UK can receive a 30-day exempt stamp upon arrival in Thailand and are eligible to extend their stay for an additional 30 days at the local immigration office. However, it's important to have a return or onward ticket to board the flight. Some immigration offices may have specific requirements, such as needing passport-sized photos for the extension application.
