A trafficking victim, or their minor child, spouse, parent and sibling, must have a letter from the federal Office of Refugee Resettlement (ORR) stating that pursuant to section 107(b) of the Trafficking Victims Protection Act of 2000, they are eligible for benefits to the same extent as refugees, or a T visa, or a Derivative T Visa.
The letter for an adult is called a certification letter. The letter for a child under age 18 is very similar, but is not a "certification letter" because the child does not have to meet the same requirements as an adult to get the letter from ORR. Both letters contain an initial certification or eligibility date and an expiration date 8 months later. The person may be issued a new letter at the end of the 8 months if they still meet the ORR requirements.
Eligible relatives of trafficking victims are entitled to Derivative T Visas (T-2, T-3, T-4, or T-5).
