A third issue that compounds the problems of regulating placement fees are minimum training periods for migrant domestic workers imposed by the government, ostensibly to ensure that workers are well-trained, well-informed and well-protected. By law, potential migrant domestic workers have to undergo compulsory training before they leave to work overseas. The length of these training periods vary; for Malaysia, workers have to go through 200 hours of training; for Singapore, 400 hours; and for Taiwan and Hong Kong, 600 hours. The length of training periods varies according to the perceived difficulty of learning the various destination country languages.
