What processes do I need to follow if I relocate from Chiang Mai to Hua Hin while on a Non O visa?

If you relocate from Chiang Mai to Hua Hin while on a Non O visa with a yearly extension, you will need to complete a TM28 form to notify immigration of your new address. Your landlord must also file a TM30 with immigration, showing your registration at the new location. After completing these steps, you can continue with your 90-day reporting and obtain your yearly extension at the Hua Hin immigration office.
