Hi im travelling trough bkk airport on the way to Europe normally I purchase my visa which is compulsory for me but this time im only transferring to another flight unfortunately I have to go trough immigration so the question is would I have to do a dtac form to transit im not leaving the airport
Answer summary
Travelers transiting through Bangkok airport who must pass through immigration will require a proper visa and need to submit a TDAC form. Even if you are not leaving the airport but have to go through passport control, the visa and TDAC requirements apply. However, if you hold an Australian passport, you can enter Thailand using a visa-exempt entry stamp. The specifics depend on the length of your layover.

Appears you are Australian, you don't need any visa, you enter using a free visa exempt entry stamp. How long is your layover?

You are not in transfer if you have to go through immigration and you require a visa to enter Thailand then you need a visa. What passport do you hold?

If you go through passport control at immigration at the arrival airport, you need to have a proper visa and a TDAC submission.

There is a check box to indicate whether you just transferred on the second page of the TDAC web system.
