How does the 90-day reporting rule apply after obtaining a 60-day extension on a Non-O visa in Thailand?

The user inquired about the duration of stay following a 60-day extension on a 90-day Non-O visa for family visits and the process of 90-day reporting. They were particularly concerned whether their one-year extension in January would start from their initial arrival date or the date of the current extension. Community members clarified that the one-year extension will begin from the expiration date of the current stamp, and noted that the 90-day reporting requirement is not applicable until after the one-year extension is granted.
