What are the requirements for a 90-day report on a Non-O visa in Thailand?

The discussion highlights the confusion regarding the necessity of a 90-day report for holders of a Non-O visa in Thailand. It is clarified that those on a 90-day Non-O visa do not need to file a 90-day report as this visa typically does not allow for extended stays that would trigger reporting requirements. However, there are nuanced exceptions; if individuals pursue a year extension, they become subject to the 90-day reporting rule. Community members share personal experiences, indicating that while immigration can impose fines for missed reports, in practice, many have left Thailand without issue even after overstaying the 90-day allowance.
