Do I need to update my TM30 form for a DTV visa before my 90-day reporting?

The TM30 form should be updated whenever you re-enter Thailand, and it is important for your current visa status. If your previous TM30 is still valid and covers your current address and lease duration, you can use it for your 90-day report. However, for official documents or if your address has changed, you must have an updated TM30 that matches your current visa. Responses from community members indicate that practices may vary depending on the immigration office.
