I have a extension for a O-A visa ending in Oct 28 2026. I am booking a ONE WAY flight for Feb 2026 to Bangkok. Is there any restrictions for immigration or DTAC for one way flights?
Answer summary
If you hold an O-A visa extension valid until October 28, 2026, and you are booking a one-way flight to Bangkok in February 2026, there are generally no immigration restrictions preventing you from entering Thailand. Additionally, if you have an extension and a re-entry permit, you are not required to show onward travel plans.

It's a TDAC
It's an arrival information card done on line, for anyone (non Thai) arriving. It's free.
