What do I need to know about doing my 90-day report in Phuket's immigration office?

If you're planning to do your 90-day report at the immigration office in Phuket, you typically do not need an appointment. It's recommended to visit during the 7 days prior to your 90-day deadline, bringing your passport and the TM30 form, although they may not always check the TM30 if the information is already in the system. If you've traveled within Thailand and stayed overnight, you will need a new TM30 from your hotel or landlord. Some have successfully completed this process online for convenience.
