TDAC - OK so my reading of it is that from May 1st you must submit an online TDAC, this can be done no sooner than three days before arrival but can be done any time within 3 days of arrival, so you could literally get off the plane in Thailand and make your submission before you get to passport control / immigration. As long as you get your email confirmation of TDAC before you get in front of the IO you are good to go? Is that the correct interpretation of it? TIA
TLDR : Answer Summary
This post discusses the online TDAC submission process for travelers arriving in Thailand, emphasizing that it must be completed no earlier than three days before arrival. Users confirm that submitting the TDAC upon landing, ideally before reaching immigration, is acceptable as long as the email confirmation is received in time. Several comments provide practical advice on using airport facilities to complete the submission.
