Bangkok district offices found 13 households across nine districts with at least 16 pink-card migrants registered at each address, mostly factories, flats and rentals. A special task force under the Department of Provincial Administration will inspect each case, checking actual use of the house, real residents and move-in/move-out documents. If you rent out flats or houses, or host migrant workers at a factory or dormitory, expect tighter scrutiny of your registrations and be ready to document who really lives there.
