When is the deadline for my first 90-day reporting for a retirement visa in Bangkok?

The inquiry was about the first 90-day reporting for a retirement visa, specifically whether it must be done exactly on the due date and what documents are needed. The consensus from the community indicates a reporting window of 14 days before to 7 days after the due date, which in this case is 14th June. For the first report, it has to be done in person at an immigration office, requiring minimal documents such as the completed TM47 form and the passport. After the first reporting, renewals can often be completed online, although the rules may vary by province.
