The United States is known as a destination country for transnational trafficking networks that bring foreign nationals into the U.S. for purposes of both sexual and labor exploitation.  Foreign national trafficking victims in the U.S. are primarily from Asia, Latin America, Eastern Europe, and Africa.  Sex trafficking cases of foreign national women and children brought into the U.S. are known to occur in a wide variety of locations in the commercial sex industry, such as massage parlors, hostess clubs, commercially-fronted brothels, residential brothels, escort services, and strip clubs.  Labor trafficking cases of foreign nationals brought into the U.S. occur in domestic work environments in private homes; small independently-owned family businesses such as restaurants or nail salons; peddling and begging rings; and larger-scale labor environments such as agricultural farms or large sweatshop-like factories.  These cases involve both documented and undocumented migrant workers, and they can occur in both legitimate and underground industries.
