Miami will be one of the first cities where U.S. immigration authorities will target people for deportation as early as this Sunday, according to sources who were briefed on the enforcement action.

Immigration agents will target Miami, Atlanta, Chicago, Baltimore, Denver, Houston, Los Angeles, New Orleans, New York City, and San Francisco by this weekend, congressional offices and U.S. Immigration and Customs Enforcement sources told the Miami Herald.

Earlier this week, a Trump administration official confirmed that ICE will specifically target for deportation as many as 1 million people “who have been issued final deportation orders by federal judges yet remain at large in the country.”

Among those to be targeted first, sources said: minors who came into the U.S. without their parents and have since turned 18; people who were ordered removed in absentia; and people who missed a court hearing and did not respond to letters mailed to their homes by the Department of Justice.

Two ICE enforcement briefings were held this week, one on Wednesday, led by ICE Deputy Director Matthew T. Albence, the other on Thursday by Henry Lucero, field office director for the agency’s Enforcement and Removal Operations in Phoenix.

On the call led by Albence, the target cities were mentioned, although the timing was not shared.Read more at Miami Herald
