If ICE agents do appear at your door it is important to understand that they are there to detain who they are looking for to place him or her in immigration removal proceedings. It is important to recognize this since a ruse often used by Immigration Agents is to pose as local law enforcement. If you do come into contact with ICE agents, do not lie or show false documents. And importantly do not sign any papers without speaking to a qualified immigration lawyer. The best advice is probably to not answer the door.
