What should I do when Immigration or other law enforcement approach me on the street?

You generally have the right to REMAIN SILENT. You do not have to answer questions about your immigration status, where you were born, where you live, where you are from, or whether you have documents. Even if you have answered some of their questions, you can decide to not answer more questions. You should never lie about your immigration status, as that can have serious consequences.
You have the right to SPEAK TO A LAWYER. You should speak to a lawyer before you answer questions about your background or immigration status.
If you have valid immigration documents, you should show them when asked. The law requires immigrants who have been issued valid immigration documents to carry those documents with them at all times. If you are undocumented, you can refuse to answer questions about your immigration status or whether you have documents.
