Hi, I've just flown into Thailand from Malaysia and have noticed that the TM6 departure card has not been stamped by immigration but my passport has. Is this an issue or is it Ok? I am currently here on a visa exemption.
TLDR : Answer Summary
Users have confirmed that it is not unusual for the TM6 departure card to remain unstamped, as the important validation for your stay is the stamp in your passport. This situation does not pose any issues and is fairly common among travelers.
