Anonymous participant right, and that's because Koh Phangan, Koh Samui and Jomtien all tell people who enter on 60 day free stamp OR real 60 day tourist visas to come when they have a week or less left on your stamp

BUT

You aren't here free stamp or on a tourist visa 😮 you have a Destination Thailand Visa and you could have applied for a new extension any time you had 30 days or less left on your entry stamp 🙁

The best way to do it would be to move the stamps to the new passport then file the 90 day report under the new passport number so that the new passport number will be in the 90 day reporting system meaning you can do the following 90 day reports online.

Anonymous participant seeing as an extension is for 180 days (it can't be issued any shorter) they aren't gonna care in the least when you're leaving the country

It's all down to the documentation (which is pretty much a carbon copy of the stuff you used to get the DTV at the consulate AND the proof you have 500K baht in a bank account in your name for a month

Anonymous participant report back if you can on how it goes for you

Best of Luck with it, the DTV extensions are pretty hit-or-miss at immigrations

Anonymous participant 237 you do NOT, there is no "playing with luck and fire"

When you stamp out on an extension (without a re-entry permit) you're "off that extension" <- meaning you can't re-enter on it

AND

That means you CAN buy a new visa to enter thailand on

Anonymous participant 237 many MANY people kept their ED extensions and went to a thai consulate in another country to get a DTV, without any problem what so ever

@Mathew *******

you are confused, the O/P is NOT on a valid VISA, they are here on an extension of stay and even WITH a re-entry permit there's no issue going out of the country to get a DTV

Many MANY people have done exactly that <- left the country with a valid ED extension gotten their DTV and came back without any issue at all

@Christine ********

The school can't do it without him sitting there at the immigration office as the extension is in his passport

So what that means is that's the day you need to have your ducks in a row by because you need to go with him to immigrations on that date and cancel your extension too <- you lose your extension the same day the primary visa/extension holder loses theirs because yours is piggy backed to theirs

@Christine ********

you are getting yearly extensions of stays that match the primary visa/extension holder than.

@Christine ********

look at the stamp in your passpot, it will clearly say in english "extension of stay permitted until" and have a date you're allowed to be here during it
