Does my dual citizen spouse need a visa to travel to Thailand?

My Visa, based on marriage, has been approved. I confirmed this with Delta on their app. Pretty simple. Under my ticket, I was asked to confirm my Visa. That is it. I have printed my payment and confirmation for my travel and have them saved on my phone. I will complete the TDAC about three days before I leave

My question is my spouse. She is a dual citizen. Under her Delta ticket, it looks like she needs a Visa also. Does anyone know what that is called? And does that get completed through our Consulate? Thank you

TLDR : Answer Summary
The user confirmed their visa for travel to Thailand based on marriage and is inquiring about the visa requirements for their dual citizen spouse traveling with Delta Air Lines. Responses indicate that if the spouse is Thai, she doesn't require a visa or to complete the TDAC. Additional clarification on the passport to be used for travel is also discussed.
Thailand Digital Arrival Card (TDAC)

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.

Which passport will she use?

I think she just needs to add her Thai passport to our flight data. Delta has her USA passport information. I think once she does that, the request may go away.

TDAC is 72, or less, hours before landing. Not from departing.

yep, I will fill out on the 21st of Oct. We land on the 24th of Oct. And it looks like I can apply through the Delta app.

Just count back from time you land. Do it any time within that 72 hours.

Is she Thai? If so she doesn’t need a visa nor to do the TDAC.

is her US passport attached to her Delta profile.

that is why they are saying that. They would tellmy Ex she needed a visa until she pulled out her thai passport. She would enter and leave the US on her US passport and enter thailand on her Thai passport

yes, she is Thai. Looking at her ticket on the Delta app, it asks for certain tasks to be completed. Visa and TDAC. She is a dual citizen. We think she just needs to upload her Thai Passport also.
