Do I need to fill out anything when entering Thailand?

Currently (as of February 2025), you don't need to fill out anything, since the TM6 form, or the so-called Arrival/Departure card, was abolished in 2022. However, according to published official information, it will be reinstated on July 1, 2025. So if you are reading this answer after July 1, 2025, then you need to fill out the form. The form is easy to fill out; blanks are given out on planes or you can take them before passport control. It takes 1-2 minutes to fill out. Then you just need to hand this form along with your passport to the border control window. We have a separate instruction on how to fill out the form - https://nashaplaneta.net/asia/thai/visas-immigracionaya-karta .

In addition, you may need to fill out a customs declaration if you are carrying something from the restricted list or exceeding non-declarable limits, including a large amount of currency. This is usually rare for tourists, but if in doubt, we recommend reading all about customs rules here - https://nashaplaneta.net/asia/thai/customs.html
