Of the 177,000 illegal aliens released, 54,000 had blank addresses, while the rest had either invalid or non-existent addresses. Some locations on the address forms were used 50 times, including a restaurant in Maryland, a bus station in Georgia, a car dealership in New Jersey, and a church in Illinois.

Obviously, if there's no address, there's no way that DHS can send the illegal alien notice of his or her immigration hearing. And in the course of vetting the illegals for criminal activity or national security risks, without a valid address they can never be arrested and deported.

"ICE must be able to locate migrants to enforce immigration laws, including to arrest or remove individuals who are considered potential threats to national security," the report said. "The notable percentage of missing, invalid for delivery or duplicate addresses on file means DHS may not be able to locate migrants following their release into the United States."
