When does the 90-day report due date start from in Thailand after re-entering the country?

In Thailand, the 90-day reporting period for foreigners starts from the date of their last entry into the country, not from the date of visa renewal or extension. This means that regardless of when a visa is extended, the countdown for the 90-day report begins anew from each entry. The responsibility to keep track of these dates lies with the individual, and an officer will stamp the passport with the due date for the next report after each submission. Additionally, there can be inconsistencies in how different immigration offices handle these reports, so it's essential for expats to be proactive in managing their reporting obligations.
