This roll call video explores the role placed upon non-federal law enforcement officials when a victim of human trafficking applies for long-term immigration relief, such as a T visa or U visa application.  Officers may be required to certify, in writing, that the victim assisted in the detection, investigation, or prosecution of the crime.  Featured are a panel of experts from local law enforcement, U.S. Immigration and Customs Enforcement and the U.S. Citizenship and Immigration Services who describe T and U visas and specifically addresses the issues surrounding the certification process.
