According to section 38 of the 1979 immigration act, "House owners, heads of household, landlords or managers of hotels who accommodate foreign nationals on a temporary basis who stay in the kingdom legally, must notify the local immigration authorities within 24 hours from the time of arrival of the foreign national."
If there is no immigration office in the province or locality of the respective house or hotel, the notification is made to the local police station. In Bangkok the notification is made to the Immigration Bureau. The notification of residence of foreign nationals is made by the manager of licensed hotels according to the hotel act, owners of guesthouses, mansions, apartments and rented houses using the form TM. 30.
The notification of residence of foreign nationals within 24 hours can be made in a number of ways to make the notification as convenient as possible:
* In person at the respective office, or
* Through an authorised person at the respective office, or
* By registered mail, or
* Via internet.
