Can UK passport holders still extend their stay in Thailand from 60 days to 90 days, and how is this done?

UK passport holders can enter Thailand for 60 days, with the possibility of extending their stay to 90 days. To extend your stay, you can typically apply for an extension at your local Thai Immigration office within 30 days of your arrival date. However, be aware that some offices, like the Jomtien Immigration office in Pattaya, have specific timelines for accepting extension applications.
