How does the DTV visa extension process work in Thailand?

The process of extending a DTV visa in Thailand involves several steps. You can extend your visa for an additional 180 days, but this can only be done once per entry. After this extension, you will need to do a 'border run' if you wish to stay longer, meaning you must leave Thailand and re-enter. Alternatively, you can extend your visa at an immigration office, but this can be more complicated as it requires documentation similar to your initial application, plus proof of financial stability (such as having $500,000 in a bank account for at least 30 days) and may involve a waiting period. Additionally, it’s important to file a 90-day report at a local immigration office during your stay.
