Each year, hundreds of thousands of people from around the world are recruited to work in the United States on temporary work visas. Internationally recruited workers are employed in a wide range of U.S. industries, from low-wage jobs in agriculture and landscaping to higher-wage jobs in technology, nursing and teaching. Regardless of visa category, employment sector, race, gender or national origin, internationally recruited workers face disturbingly common patterns of recruitment abuse, including fraud, discrimination, severe economic coercion, retaliation, blacklisting and, in some cases, forced labour, indentured servitude, debt bondage and human trafficking. This report shows how structural flaws in work visa programs increase the vulnerability of workers to human trafficking.
