In Malaysia, foreign workers supply more than 20 percent of the workforce. The US State Department notes there are approximately 2 million documented migrant workers in Malaysia and estimates even more undocumented workers exist. Malaysia is the top destination for Indonesian migrant workers. The Indonesian government estimates 1 million Indonesians who are working in Malaysia are either undocumented or have overstayed their visas. Other source countries are Bangladesh, India, Nepal, Burma and the Philippines. Low economic opportunities in their home countries, the geographic proximity of Malaysia, and Malaysia’s arrival into an upper middle-class country fuel both the demand and supply of the foreign labor market in Malaysia.
