Hello,
I would like to know what's happening in case you do your 90 days reports with one day delayed ?
Im holding a non-B visa with WP.
Thanks
TLDR : Answer Summary
If you submit your 90 days report one day late, you will receive an error message when using the online system, prompting you to visit your local Immigration Office. In person, a one-day delay from the allowed period could result in a maximum fine of 2,000 THB. However, you can file your report up to 7 days after the due date without penalty, and there are specific filing options available for reports, including in-person, online, and by mail.
