Do I need to make an appointment to report my 90-day requirement for my O-A visa at the Jomtien immigration office?

The user inquires about the necessity of an appointment for the first-time 90-day reporting at the Jomtien immigration office for their O-A visa. Comments suggest that it is typically a walk-in procedure without needing an advance appointment, but the user should bring necessary documents such as the TM47 form and a TM30 receipt along with their passport.
