requirement is based on Section 37(5) of the Immigration Act B.E. 2522. Specifically for the DTV, Thai Immigration Order #

(2024) confirms that DTV holders must follow these reporting procedures.
How to Stay Compliant
The 90-Day Clock: Your count starts the day you enter Thailand. If you stay for 90 days straight without leaving, you must report.
The Reset Button: Every time you leave Thailand and re-enter, the clock resets to zero. Since your DTV is multiple-entry, taking a quick trip abroad before day 90 means you never have to file a report.
How to Report: If you do stay past 90 days, you can report in person at a local immigration office, by mail, or online (though the first report often must be done in person).
Timing: You must report within 15 days before or 7 days after your 90th day. Missing this window usually results in a 2,000 THB fine.
