there are a few options if you'll actually run out a day early.

1) depending on your flight time, you can try checking in early and crossing through passport control before midnight

2) you can go 2-3 days before your extension expires and see if they'll accept an extension application that you don't qualify for. If they accept the application, they'll give you a 7-day "extension denied" stamp starting from the day of application.

3) overstay one day. There's no fine for one day overstay if leaving from an airport.

A tourist visa wouldn't benefit you. You would get 60 days when you entered and then that would be invalidated when you left 4 days later. Paying for a visa for 4 days would be pretty wasteful.

I'm a little confused. Which extension are you applying for? They will 100% not add an extra day for you, so you can forget about that option. But it's hard to say what options you might have because your post is confusing and doesn't include enough information like when you entered, when your entry stamp went until, what extension you are applying for and when it will go until.

they're not being more strict with border runs. They're being more strict with people entering Thailand visa exempt, without a visa. You have a visa.

That says ITINERARY, it does not anywhere say you need a ticket. The e-visa application for non-O just asks for flight information in and flight information out. A quick google flights search can get you that information. It's just ticking off a box because a non-O is only valid for 90 days, so you give a flight out within 90 days and done.

There's no requirement to stay out any nights. Who told you there was?

@Dawn ******

What is the game plan then? Is this just a temporary trip to Thailand? Otherwise the only option moving forward is going to be extensions, or returning back to the US every 2 years to apply for a new non-OA visa.

While it's at the discretion of the embassy, there's no reason that shouldn't work.

ALL Immigration offices in the country will be closed the following days in December:

Friday December 5th

Wednesday December 10th

Wednesday December 31st

Thursday January 1st

Friday January 2nd

A visa grants you the full stay from the day you arrive. The day you arrive is counted as day 1 and you'll receive 89 additional days after that.

Departure information isn't mandatory for ANYONE on the TDAC. It's not a mandatory field. Don't touch it and it will remain not required. Touch it and it all becomes mandatory.
