The U.S. Department of Homeland Security published a tool that provides an overview for law enforcement and other government agencies (including judges) authorized by the U Visa statutes, regulations and policies to sign U visa certifications. The overview describes the role of a certifier, what constitutes U Visa criminal activity, which government agencies are eligible to certify, who can sign a certification, when a certification may be signed, tips for completing the certification, and includes phone numbers, websites and resources available to assist certifiers from DHS and United States Citizenship and Immigration Services.
