The T visa is for immigrant victims of human trafficking. Forced labor: when a person is recruited, transported or housed for forced, threatened or deceived labor. The result is that the person provides services in a situation similar to that of slavery or involuntary servitude or debt bondage.
Sexual exploitation: when a minor under 18 years of age is induced into prostitution. And also when a person over that age is recruited, housed or transported and by means of fraud, coercion or force is forced into prostitution. That is, what is known as white slavery.
