Local Police & ICE: Know Your Rights as an Immigrant

Local police generally cannot detain you solely for immigration purposes unless your city or county has a formal agreement with ICE. You have the right to remain silent and to refuse consent to a search regardless of immigration status. If an officer asks about your status, you may politely decline to answer. Contact an immigration attorney immediately if you are detained.

Quick Answer

Local police can stop you for suspected criminal activity, but most jurisdictions do not have the authority to hold you in jail solely on behalf of ICE without a criminal warrant signed by a judge. Whether local officers cooperate with ICE depends heavily on your city or county's "sanctuary" policies and any formal agreements—called 287(g) agreements—between local law enforcement and ICE. Know your rights before any encounter.

When Local Police Can (and Cannot) Cooperate with ICE

The level of cooperation between local police and ICE varies significantly depending on where you live:

• Sanctuary cities and counties: Many jurisdictions have policies limiting or prohibiting local officers from asking about immigration status or honoring ICE civil detainer requests (voluntary hold requests that ask jails to keep someone extra time for ICE pickup).
• 287(g) agreements: Under Section 287(g) of the Immigration and Nationality Act (INA), local law enforcement agencies can sign agreements with ICE that give certain officers limited immigration enforcement powers. In these jurisdictions, local police may check immigration status and place holds.
• ICE civil detainers: An ICE detainer is a request, not a court order. Courts have ruled that local jails are not legally required to honor civil detainers. However, some jurisdictions still comply voluntarily.
• Criminal warrants vs. immigration warrants: Only a warrant signed by a federal judge obligates detention. An ICE administrative warrant (Form I-200 or I-205) is not a judicial warrant and does not compel local police to detain you.

Immigration attorney Ilya Fishkin, immigration attorney, advises immigrants to research the specific policies of their local jurisdiction so they know what to expect before any encounter with law enforcement.

Your Rights During a Police Stop: Step-by-Step

1. Stay calm and keep your hands visible. Do not run or resist, even if you believe the stop is unlawful. Any resistance can be used against you.
2. Invoke your right to remain silent. Under the Fifth Amendment, you are not required to answer questions about your immigration status. Clearly state: "I am exercising my right to remain silent."
3. Refuse consent to searches. Clearly and calmly say: "I do not consent to a search." Officers may still search if they have probable cause or a warrant, but your refusal is on record.
4. Ask if you are free to go. If the officer says yes, calmly walk away. If you are being detained, ask: "Am I under arrest? What is the charge?"
5. Do not show immigration documents voluntarily. You are generally not required to carry immigration papers unless you are a non-citizen over 18 required to register under INA §264. Consult an attorney about your specific situation.
6. Contact an immigration attorney immediately. If detained, ask for a lawyer right away. Do not sign any documents before speaking with legal counsel.

What the Law Says

Several key legal provisions govern the relationship between local police and federal immigration enforcement:

• INA §287(g) — authorizes formal agreements between DHS/ICE and local law enforcement agencies, granting limited immigration enforcement powers to participating officers.
• Fourth Amendment — protects all persons in the United States, regardless of immigration status, from unreasonable searches and seizures. An arrest requires probable cause or a valid judicial warrant.
• Fifth Amendment — guarantees the right to remain silent and protects against self-incrimination. You are not required to answer questions about where you were born or how you entered the country.
• Tenth Amendment / Anti-Commandeering Doctrine — federal courts have consistently held that the federal government cannot compel state or local officers to enforce federal immigration law, which is why sanctuary policies are legally defensible.
• INA §264 — requires certain non-citizens to carry registration documents. Failure to do so can be a misdemeanor, so know what documents apply to your status.

What to Do After a Police Encounter

• Write down everything you remember: officer names, badge numbers, what was said, and what happened — as soon as possible.
• Contact a licensed immigration attorney to assess whether your rights were violated and whether any enforcement action is pending.
• If you receive an ICE notice or a notice to appear (NTA), do not ignore it. Missing an immigration court hearing can result in a deportation order issued in absentia.
• If deportation proceedings are initiated, you have the right to appeal. An order of removal can be appealed within 30 days, and a Motion to Reopen can generally be filed within 90 days.
