Is TM.30 required for extending my student visa in Thailand?

The TM.30 form is generally required for immigration processes in Thailand, including visa extensions. It's the responsibility of the landlord to submit this form. If your landlord has not submitted the TM.30 yet, it is advisable to have them do so, or you might consider staying at a hotel temporarily and completing your 90-day report. When submitting the TM.30, ensure that your landlord provides the necessary documents, including their Thai ID and house registration details, either in-person or possibly online if they are registered.
