Is there a grace period for the 90-day immigration report if I leave Thailand shortly after my 90-day period?

Nope, 😮 Doesn't work that way. 😕

That isn't a "grace period" where if you leave during that time you don't have to apply

The window of opportunity to file a 90 day report in person is from 2 weeks before the due date until 1 week after.

The rule is clear, spend 90 continuous days inside thailand (on a visa/extension that requires it) and you have to file a 90 day report.
