How can you extend your OA visa while living in Thailand?

To extend your OA visa in Thailand, you must fulfill certain financial requirements, including showing 800,000 baht in a Thai bank account for at least three months prior to your application. Alternatively, you can leave Thailand before your visa expires and re-enter with a new insurance certificate to receive another year on your visa. This method is commonly referred to as a 'border bounce.' You do not need a re-entry permit when bouncing back in as long as you do so before the expiry date of your visa. For subsequent years, you can continue to extend your OA visa by meeting the same financial and insurance requirements or switch to a Non-O visa, which has different criteria.
