The TM30 system records where a foreigner lives in Thailand. It helps immigration keep track of residential addresses for visitors holding tourist, education, retirement, or business visas. The 90-day report, meanwhile, confirms that a foreigner who remains in Thailand has not changed location or left the country without re-entry. Both processes are administrative rather than restrictive, and completing them correctly saves time later when extending or converting visas.

TM30 stands for “Notification of Residence for Aliens.” It must be filed whenever a foreigner arrives at a new address. The form includes passport details, visa type, and the exact location of accommodation. In Chiang Mai, hotels and guesthouses automatically submit this information to immigration. However, those living in apartments, rented houses, or private condos must ensure that either the landlord or the tenant submits it within twenty-four hours of arrival. The process can be done at the Chiang Mai Immigration Office near Promenada Mall, through the official website, or via the TM30 mobile app.

Technically, the responsibility lies with the property owner. Yet in many cases, especially with private rentals, foreigners handle it themselves to avoid delays. If you rent through an agent, ask whether the TM30 has been submitted. When unsure, visit immigration with a printed copy of your rental contract, passport photo page, visa page, and departure card (TM6) to verify. The officers can confirm or re-register your address in minutes. Keeping the TM30 receipt stapled into your passport is recommended because you will need it for visa extensions and 90-day reports.

Any foreigner staying in Thailand longer than ninety consecutive days must confirm their address every ninety days from their latest arrival or last report. The countdown restarts each time you leave and re-enter the country. In Chiang Mai, reports can be made fifteen days before or seven days after the due date without penalty. Late submissions may result in a small fine. Keeping reminders in your calendar ensures that the process stays routine rather than stressful.

1. In person
Visit Chiang Mai Immigration with your passport, previous TM30 receipt, and completed TM47 form. The process usually takes less than fifteen minutes if done in the morning.

2. Online
Submit through https://www.immigration.go.th. The site accepts reports between fifteen and seven days before the due date. Approval messages appear within a few days.

3. By mail
Less common but still valid. Send the TM47 form, passport copy, and stamped self-addressed envelope to the Chiang Mai Immigration Office at least one week before your due date. A new receipt will be mailed back to you.

Once accepted, immigration issues a small slip noting your next reporting date. Keep it inside your passport as proof of compliance.

• Forgetting to renew the TM30 after returning from another province or country. Each re-entry requires a new address update.
• Missing the ninety-day window. Add a digital calendar alert or paper note inside your passport.
• Assuming landlords always handle it. Many do not, especially with short-term leases.
• Not printing confirmations. Having a paper copy simplifies future extensions or visa changes.

Following these small habits ensures smooth communication with immigration officers and saves time.

Keep digital and printed copies of all immigration documents in one folder. Many residents label it with their passport number and renewal dates. If you plan to move apartments or travel frequently, choose accommodations familiar with foreign reporting so paperwork stays up to date.
Using a local SIM with unlimited data allows quick access to the immigration apps, and staying informed through community groups like “Chiang Mai Digital Nomads” or “Chiang Mai Visa & Immigration Forum” on Facebook helps you catch small rule changes early.
