Illegal immigration to Malaysia
Illegal immigration to Malaysia is the cross-border movement of people to Malaysia under conditions where official authorisation is lacking, breached, expired, fraudulent, or irregular. The cross-border movement of workers has become well-established in Southeast Asia, with Malaysia a major labour-receiving country and Indonesia and the Philippines the region's main labour-sending states.
