Do I need to cancel my Non Immigrant ED Visa in person before applying for a DTV visa from the USA?

However, I left before my first 90 day extension. So after the first extension you're on the hook or your sponsor is and the sponsor can write a letter saying you've left early so immigration had a clear paper trail.

I literally just did this...there is no fine. Once you stamp out, you're out. As long as you do not overstay your visa you are good to go.

If you were stamped out by Thai immigration before your visa or extension expired, you’re fine — no penalty.

The overstay clock stops the moment you’re stamped out.

But if your extension had already expired before you left, even by a day, then yes — they’ll fine you on departure, right there at the airport. The officer calculates the number of days you overstayed and charges 500 baht per day, capped at 20,000 baht. Once you pay, you can leave freely.

If you cleared the checkpoint before expiration, you owe nothing, and when you later come back on a DTV visa, you’re entering clean.

So the simple rule:

Left before expiry → no fine, no issue.

Left after expiry → fined on departure, but usually no long-term problem if the overstay was short.

that will invalidate it if no re-entry permit was purchased. But that doesn't mean it was cancelled properly and is a failure to meet the requirements that were signed when getting the extension.

understand and agreed. What if I am out of the country but can not come back to Thailand within the permit date? For example, my visa will expire 10. November 2025. And I leave Thailand today. But something happens to me in the meantime, so I can not back to Thailand to renew or extend or cancel my visa by 10.Nov.2025.because I am not able to be in Thailand in time. So, what will happen to my visa? When I am back to Thailand, let me say, January, my visa is already expired. I need to apply new visa? or shall I be back to Thailand on tourism visa and cancel it at the immigration although it is already expired? then can I apply a new one?
