What is the purpose of the TM28 form for expats in Thailand returning home after being away?

The TM28 form is required for expats in Thailand to report their return to their registered residence after being away for 24 hours or more. It's important for maintaining proper immigration records, particularly if you are also submitting a 90-day report at an immigration office. The process varies by region, and some immigration offices may not require it unless a change of address occurs. There can be misunderstandings around the usage of TM28 and TM30 forms, as TM28 is specifically for indicating a return home, while TM30 is for reporting residence at a specific address.
