Do I need to make multiple appointments for a 90-day report in Thailand if reporting for three people?

When reporting for multiple individuals for a 90-day report in Thailand, you need to make separate appointments for each person, using the name on their respective passports. You cannot book more than one appointment under your name. However, you can take all the passports to the appointment and file the reports for all individuals at once. Alternatively, you may not need to make an appointment at all and can just show up to report.
