"ICE officers and agents are on the streets every day, prioritizing public safety by locating, arresting and removing criminal aliens and immigration violators from our neighborhoods.
ICE does not need judicial warrants to make arrests. Like all other law enforcement officers, ICE officers and agents can initiate consensual encounters and speak with people, briefly detain aliens when they have reasonable suspicion that the aliens are illegally present in the United States, and arrest people they believe are illegal aliens. ICE officers and agents can also detain and search people crossing the border.
All aliens who violate U.S. immigration law are subject to arrest and detention, regardless of their criminal histories. Those with final orders of removal are removed from the United States."
