IF YOU ARE QUESTIONED ABOUT YOUR IMMIGRATION STATUS

You have the right to remain silent and do not have to discuss your immigration or citizenship status with police, immigration agents or any other officials. You do not have to answer questions about where you were born, whether you are a U.S. citizen, or how you entered the country. (Separate rules apply at international borders and airports, and for individuals on certain nonimmigrant visas, including tourists and business travelers.)

If you are not a U.S. citizen and an immigration agent requests your immigration papers, you must show them if you have them with you.If you are over 18, carry your immigration documents with you at all times. If you do not have immigration papers, say you want to remain silent.

Do not lie about your citizenship status or provide fake documents.

IF THE POLICE OR IMMIGRATION AGENTS COME TO YOUR HOME

If the police or immigration agents come to your home, you do not have to let them in unless they have certain kinds of warrants.

Ask the officer to slip the warrant under the door or hold it up to the window so you can inspect it. A search warrant allows police to enter the address listed on the warrant, but officers can only search the areas and for the items listed. An arrest warrant allows police to enter the home of the person listed on the warrant if they believe the person is inside. A warrant of removal/deportation (ICE warrant) does not allow officers to enter a home without consent.

Even if officers have a warrant, you have the right to remain silent. If you choose to speak to the officers, step outside and close the door.
