For example, if you rent a condo for say 6 months then you move to live in another condo, you need to inform immigration of your new address.

Many foreigners, including those who have lived in Thailand for a number of years, didn’t even know the requirement existed.

At least that was the case until last year when TM28 briefly started being more strictly enforced by some immigration offices.

This coincided with immigration also strictly enforcing TM30 - the requirement for hotels, guesthouses and property owners to report foreigners staying at their address.
