No longer a homogeneous country, the Republic of Korea faces diverse social problems related to foreign residents in its society. One large proportion of the foreign residents is foreign female workers, mostly from Southeast Asian countries such as Philippines, Taiwan, and Vietnam. Unlike foreign women coming to Korea for international marriage, the female workers come to Korea to remit money they earn back to their families in home countries. The problem is, many of these foreign female workers become targets of Korean brokers who force them into the sex industry by threatening them due to their weak legal status and visas.
