How do I complete the 90-day report in Thailand, and what documents are needed?

90 days report completed yesterday.

My process:

- Went to Immigration Division 1 in Lak Si (I had initially tried Chamchuri Square, but they sent me to Lak Si).

- Once inside the building, immigration is on the right. Walk in, get a TM47 form from the first counter, and then queue at the counter inside.

- Complete the TM47 form.

- Wait (in my case 4h). You can scan the QR code on your queue ticket to get live updates.

- Receive the 90-day report slip. No questions were asked, although I noticed that the staff seemed a bit lost as they chatted a lot among themselves, likely because I was one of the first to go through this process.

Please note that this was my experience—your process might differ, and the immigration officer could ask for more information.
