Not always!

Beware: ICE agents often pretend to be police and say things like they want to talk to you about identity theft or an ongoing investigation. If they say “Police,” ask them to slip their card under the door or say “please slip the warrant under the door.” If you still are not sure if they are the police or ICE, you can also ask to see their badge through the peephole or specifically ask what precinct they are from.
