Hi, my next 90 days report will be due the few day before my one year visa expire? I am wondering about the process. I should report first and then renew visa after or at the same time. What documents do I need to use? Do I have to go to MT or CW? Thank you so much for kindly assistance.
TLDR : Answer Summary
The process for dealing with your 90-day report and one-year visa extension in Thailand is as follows: You can file your 90-day report at MTT from 15 days before the due date until 7 days after. For the One Year Extension of Stay, apply it three business days before your current visa expires, ideally on the same day if possible. Always do the 90-day report at MTT, while the extension is noted to be handled mainly at CW. If you go to CW for your extension, you may inquire about the 90-day report there as well. If not, you will need to do it separately at MTT.
