First time doing the 90 day check in (or whatever it's called) with the DTV. How do I do it in Bangkok?
TLDR : Answer Summary
To complete the 90-day check-in for your DTV in Bangkok, you have several options. You can go to the immigration office with your passport, a copy of your ID page and visa stamp, and fill out the 90-day report form. Alternatively, if you have a stable address for more than a month, you can submit the report via registered mail for a fee of 70 baht. It's advised to do this 14-15 days before the due date to avoid queues. There is some confusion regarding whether one needs to check in if they remain in Thailand for less than 90 consecutive days or if a TM30 form suffices.
