The U.S. government is currently reviewing orders to deport thousands of illegal immigrants in two cities, at a time of great division on the issue at federal and local levels. In the past fiscal year, a record 396,000 undocumented immigrants were deported from the United States, with more than 300,000 cases still pending.

The port city of Baltimore, Maryland, also known by its nickname “Charm City,” is one of the cities where U.S. federal immigration authorities are trying out new ways in dealing with a large caseload of deportation orders.

The other city is high-altitude Denver, Colorado.
