You are required to report to immigration after 90 consecutive days of stay in Thailand. Your first report must be submitted in person no later than 89 days after your arrival date, or within the reporting window โ from 15 days before to 7 days after the due date.
In addition to this, the property owner or the hotel must submit a TM30 address registration for you to immigration within 24 hours of your arrival.
