How do I extend my DTV visa in Thailand, and what is the process for obtaining a 180-day stamp?

The process for extending a DTV visa in Thailand raises some confusion among expats. Firstly, to extend a 180-day stay at the immigration office, one must typically provide the same documents as during the initial DTV application, with no guarantee of approval. Conversely, leaving Thailand and returning can grant an automatic stamp upon re-entry. Additionally, regarding the new passport check system, expats are currently required to present their passport and visa to an immigration officer, as only exit machines are fully automated. Therefore, it's recommended to avoid extensions and consider traveling abroad every few months instead.
