The 'T' nonimmigrant status, also known as the 'T' visa, was created to provide immigration protection to victims of a severe form of human trafficking. The 'U' nonimmigrant status, or 'U' visa, is designated for victims of certain crimes who have suffered mental or physical abuse because of the crime and who are willing to assist law enforcement and government officials in the investigation of the criminal activity."
