I always put the max allowable stay per entry: 180 days.

You don't and can't get your DTV transferred to a new passport. Bring both passports with you.

Apparently, if it's an e-visa, then there is no need to travel with your old passport but you should bring a photocopy of the old passport along with the e-visa paper. If it's a visa sticker, bring along both passports throughout the duration of the DTV.

Nothing special really. For now, if you enter by air and you have a visa sticker, make sure to show that to the officer. If it's an e-visa, print it out.

At a land border, fill out a TM6 form (the paper version) and write your visa number on there. The officer will find your visa (but do present the paper version, if it's an e-visa).

Some land borders temporarily exempt travelers from having to fill in a TM6 including Sadao, Nong Khai, Mukdahan and Aranyaprathet (including Ban Khao Din, which is under their jurisdiction). At these borders, show the officer your visa so they don't accidentally stamp you in on visa exempt.

That's it.

Try an agent in Bangkok or Pattaya.

My son holds 4 too and it's the same for him. Expiry 5 years from the date of issue minus one day.

@Nick ******

Very true. I am a holder of multiple nationalities and every country does it this way.

Aha I see. I hope they can wait for you in Thailand then. I also hope your visa will be approved soon so you can meet them there.

@Sean ******

Sure. My point is that this is most likely to happen on your first entry on the DTV, especially if you do a same day switch rather than say in 1 or 2 years from now. This is because it's easiest to pick up at the beginning. An officer who is looking to refuse entry on a DTV due to fraud, probably wouldn't allow entry and only do an investigation after the holder has been re-entering the country a year or two into their DTV validity.

@Robert ******

I only made a comment, correcting you about Thai nationals and the TM6, which is to say that until 2017, they were included.

As for this online TM6, we don't know for sure whether it will enter into force on May 1. That's simply what the news is saying now.

I never said I knew anything about it, beyond what the news is saying. On the contrary, I've suggested waiting until the government clarifies the situation.

They're correct. Even passports expire 5 or 10 years from the date of issue minus one day. So if your passport was issued on January 29, 2025, it will expire on January 28, 2035, not January 29.
