Can I extend my DTV visa stay at the immigration office or do I need to leave Thailand?

As you approach the end of your 180-day DTV visa stay, it seems you have two primary options concerning your extension: the possibility of extending at an immigration office or leaving the country to re-enter. Most commenters agree that while technically you can ask for a 180-day extension in Thailand, it often involves significant paperwork and challenges, as immigration may require updated documentation such as a bank balance of 500,000 baht. Many suggest that it is much simpler to leave Thailand for at least 48 hours and then return to gain a new 180-day entry, with one user emphasizing that there are reports of issues if you stay out for less than 48 hours. Overall, leaving and re-entering is largely viewed as the more practical route.
