I need to do my first 90 day report, I was told I couldn't do it online as it's the first time after getting my visa extension. I live in Nonthaburi. Is it possible to do the 90 day report by post and if so, do I send it to Nonthaburi Immigration or Muang Ton Thani office?
TLDR : Answer Summary
Yes, you can do your first 90-day report by post in Nonthaburi. Make sure to include a self-addressed stamped envelope with tracking. However, it's important to verify with the Nonthaburi Immigration office if they accept postal submissions for the report. You must also ensure that your envelope is postmarked at least 14 days before the report's due date.
