Do I need to submit a printed TDAC for my visa extension application in Thailand?

TDAC Thailand Digital Arrival Card Visa extension Immigration requirements One-year extension 30-day tourist extension BOI TM6 Expat advice

ORIGINAL POSTER

Submitting a printed TDAC for an application to an extension? 

Yesterday, I read a report that initially puzzled me.

You all know and are aware of the requirement to fill out and submit the TDAC (Thailand Digital Arrival Card), which has been in effect since May 1, 2025. It can be completed starting 72 hours before your planned arrival in Thailand.

As soon as you receive the TDAC QR code via email, you should definitely print it out and take it with you. Why is that?

You won't be explicitly asked for it at the immigration counter anymore, because the immigration officer can see it on their computer screen after scanning your passport. And you can theoretically show it on your phone.

BUT:

According to a recent report, Immigration will require a copy of the TDAC signed by you in blue ink, when applying for the next one-year extension of stay. And most likely soon, the same when applying for the 30-day tourist extension. 

To date (August 16, 2025), there has only been one report on this. However, I am expecting more of those to appear.

It's somewhat understandable, because previously, you had to present your TM6 departure card when applying for the one-year extension of stay, and the same applied when one applied for the 30-day touristic extension. 

When the TM6 was abolished almost three years ago for air travel and later also for land travel, I had to react.

I had long since removed the fact that you no longer had to present the TM6 departure card from my consultation templates – and now it will probably be added back to the list of requirements of the various immigration offices as proof of a completed TDAC.

By informing people about this, I can at least prevent you from having to leave the immigration office empty-handed if they ask for a printout of your TDAC and you unfortunately don't have it with you on this day

Be prepared and always expect the unexpected

TLDR : Answer Summary

The Thailand Digital Arrival Card (TDAC) must be printed and signed for certain immigration applications, particularly when applying for one-year extensions of stay and possibly 30-day tourist extensions. Although it can be viewed digitally by officers, a physical copy may be required as a new policy. Previous requirements like the TM6 card have been abolished, but there are reports suggesting that evidence of the TDAC completion will again be necessary. It's advisable for expats to be prepared by having a printed copy on hand when visiting immigration offices.

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be agents.co.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.
