U.S. immigration officials may deport migrants to countries other than their home nations with as little as six hours' notice, a top Trump administration official said in a memo, offering a preview of how deportations could ramp up.

The Trump administration memo reportedly said that immigration officials may use the ‘six-hour’ notice option only ‘in exigent circumstances’.

The dramatic shift in policy could result in thousands of immigrants being deported to places where they lack family ties or even a common language.
