ORIGINAL POSTER

Hello,

I have a question regarding entering Thailand with a 90-day Non-O visa.

 1. When entering Thailand, does immigration stamp 90 days from the date of entry, or is the stay granted only until the visa validity date?

 2. When completing the TDAC (arrival card), is it mandatory to provide a departure date if I hold a 90-day visa and do not yet have a confirmed return ticket?

Thank you in advance for your help.

TLDR : Answer Summary

When you enter Thailand with a 90-day Non-O visa, immigration will stamp your passport for a stay of 90 days starting from the date of your arrival, which is counted as day one. Additionally, when completing the TDAC (arrival card), providing a departure date is not mandatory; you can leave that section blank.

You can't fill In The arrival card until 72 hrs before so presumably you'll have a ticket by then

A visa grants you the full stay from the day you arrive. The day you arrive is counted as day 1 and you'll receive 89 additional days after that.

Departure information isn't mandatory for ANYONE on the TDAC. It's not a mandatory field. Don't touch it and it will remain not required. Touch it and it all becomes mandatory.
