Q : What qualifies as a "certifying agency"?

Agencies which must certify that a petitioner for U nonimmigrant status has, is, or will be helpful include federal, state, or local law enforcement agencies, or a prosecutor, judge or other authority that has responsibility for the investigation of the criminal activity.

Other agencies such as child protective services, the Equal Employment Opportunity Commission, and the Department of Labor also qualify as certifying agencies since they have criminal investigative jurisdiction within their respective areas of expertise.
