Human trafficking, also known as trafficking in persons, is a form of modern-day slavery in which traffickers typically lure individuals with false promises of employment and a better life. Victims of severe forms of human trafficking are provided relief under U.S. immigration law by the Victims of Trafficking in Persons (T) nonimmigrant visa. This status allows victims of human trafficking to remain in the United States to assist in investigations or prosecutions of human trafficking violators. Foreign citizens seeking T-1 nonimmigrant status must be physically present in the United States already, due to human trafficking.
Therefore, U.S. Embassies and Consulates (outside the United States) do not issue T-1 visas, but may issue qualifying family members T (derivative) visas.
