It's actually the most sensible reply, even if you think it's unhelpful. It varies with date, etc., so only the individual can really make an assessment. I didn't read Ben's reply as anything other than logical.

How long is your visit?

@Jeff ******

There would be something to transfer, and that would be to update the passport number in their systems, so that the new passport would be registered instead of the old. But they don't do that, and they won't.

@Greg *******

Immigration don't ISSUE the DTV, so I doubt they'd be able to create a new one for a new passport.

@Greg *******

I very much doubt it, as there's also no reason there not to just have both passports with you.

What I received was this:

"Dear Sir/Madam,

Thank you for your email. If your current passport with your visa has expired, you must carry both your old passport (containing the valid visa) and your new passport whenever you travel to Thailand. Immigration officers will refer to your visa on your old passport when processing your entry and stamp your new passport accordingly. In the event that you lose the old passport containing the visa, you will be required to apply for a new visa without exception. Please note that we are unable to transfer a visa from an old passport to a new one.

Best regards,

The Visa Team"

As the others have stated (and I have an email from the Thai authorities), you'll need to carry both passports. It is not possible (despite what some have said) to transfer your DTV to a new passport, even if you visit the immigration centre.

If you lose your old passport, or no longer have access to it, you will need to reapply for a DTV from scratch.

Anonymous participant 698 You are them tattooed to make a new visa application.

Anonymous participant 385 You can't. That's not something they will do. I have this in written confirmation from the Thai authorities. You simply need to take both your new and old passports with the DTV

@Peter *******

That's Musk. Avoid like the plague.
