Can the American police drive away illegal immigrants?

American police can't expel illegal immigrants. Illegal immigrants are handled by American border law enforcement officers. Illegal immigrants in the United States can also be released on bail, which generally requires lawyers to handle. According to relevant public information, the US Department of Homeland Security has promulgated a large number of new regulations on border security and repatriation of illegal immigrants, aiming at detaining and repatriating illegal immigrants to a greater extent, speeding up their departure and arresting illegal immigrants. Only under the most special circumstances will they be arrested.
