(Portland, OR) -- An investigation finds the Portland Police Bureau failed to protect dozens of undocumented immigrants who were victims of serious crimes. The City Ombudsman released a 13-page report this week showing the bureau denied special temporary visas known as U-Visas to over four-dozen crime victims. U-Visas allow undocumented immigrants to remain in the U.S. while police investigate crimes committed against them. The Ombudsman is recommending that the bureau bring its U-Visa certification request process into alignment with federal, state and city law.
