How do I prove that I contacted law enforcement?
Ask the law enforcement agency you contact to give you (or your lawyer) a “law enforcement agency (LEA) endorsement,” which is also known as a “declaration of law enforcement officer for victim of trafficking in persons,” on Form I-914 Supplement B. This is a statement from law enforcement saying that you have cooperated with their requests in investigating or prosecuting the case.
Getting the LEA endorsement can be very helpful to strengthen your T visa application. However, having an LEA endorsement does not guarantee that you will get T visa status. It’s possible that you can get T visa status if you show you tried to be helpful but still couldn’t get an endorsement from law enforcement.1
