The special visas granted to foreigners who work as household domestics in the U.S. leave them vulnerable to serious abuse, Human Rights Watch charged in a report released today. Thousands of these workers, typically women, enter the United States every year to work for diplomats, officials of international organizations, foreign businesspeople, and U.S. citizens temporarily back in the U.S. from their homes abroad. In the fifty-six-page report, Human Rights Watch documents the cases of dozens of workers but believes that many more are exposed to some form of abuse.
