Most of the fundamental protections in the U.S. Constitution cover everyone present in the United States, not only citizens. Based on official sources, this page explains which rules apply when you encounter police or immigration officers (ICE, CBP), what the right to remain silent means, which documents you must carry, and where to report rights violations. This page provides general information, not legal advice; consult an immigration attorney about a specific incident.
Whom does the Constitution protect?
- Fourth Amendment: people, their homes, documents, and belongings are protected against "unreasonable" searches and seizures. A search or arrest warrant may be issued only if there is probable cause, supported by an oath, and clearly specifying the place and person to be searched.
- Fifth Amendment: no person may be compelled in a criminal case to be a witness against themselves. No person may be deprived of liberty or property without due process of law.
- Sixth Amendment: in a criminal case, the accused has the right to the assistance of counsel.
- Fourteenth Amendment: states also may not deprive any person of liberty without due process of law. They may not deny anyone within their jurisdiction the equal protection of the laws.
- These amendments use the word "person," not "citizen." The U.S. Department of Justice also states that the federal laws it enforces against police misconduct protect everyone in the United States, whether or not they are citizens.
The right to remain silent
- In a criminal investigation (Miranda warning): Under the Supreme Court's 1966 decision in Miranda v. Arizona, a person in custody must be advised before questioning that:
- you have the right to remain silent;
- anything you say may be used against you in court;
- you have the right to have an attorney;
- if you cannot afford an attorney, one will be appointed for you.
- In immigration detention: A person detained without a warrant and referred for removal proceedings (except expedited removal) must be informed of the following (8 CFR 287.3):
- the reason for the detention;
- the right to be represented by an attorney at no expense to the government, meaning at your own expense;
- a list of free legal-aid organizations in the area where the case will be heard;
- that any statement you make may be used against you in subsequent proceedings.
- An immigration case is not a criminal case. The government does not appoint a free attorney for you. For free and low-cost assistance, see 12.6 Finding an attorney.
- Officers are prohibited from using threats, pressure, or physical violence to force you to waive your rights or give a statement (8 CFR 287.8).
- Remaining silent and lying are different. Knowingly and willfully making a false statement on a federal matter or using a fraudulent document is a separate crime (18 U.S.C. 1001).
Rules are different at airports and the border: A noncitizen seeking to enter the United States must personally establish to a CBP officer that they are admissible. According to CBP, everyone crossing the border is subject to inspection, including their phones and computers. A noncitizen who does not present their device for inspection may have this conduct considered in the admission decision. For entry rules, see 1.9 Entry into the United States.
If police or an immigration officer stops you on the street
- Asking questions: An immigration officer may ask anyone questions as long as the person's freedom to walk away is not restricted.
- Brief detention: If the officer has reasonable suspicion based on specific and articulable facts, they may briefly detain a person for questioning. A similar rule applies to police: if there is reasonable suspicion that a crime has been committed, they may briefly stop and question a person.
- Arrest: As a rule, an immigration officer must obtain an arrest warrant. An arrest without a warrant may be made if the person is likely to flee before a warrant can be issued. At the time of arrest, as soon as it is possible and safe, the officer must:
- identify themselves as an immigration officer authorized to make arrests;
- tell the person that they are being arrested and the reason.
- 48 hours: In a warrantless detention, except in extraordinary circumstances, a decision must be made within 48 hours whether the person will remain detained or be released on bond.
- Local police and 287(g): ICE may delegate limited immigration authority to certain state and local police agencies. According to ICE, as of October 15, 2026, there are 2,679 agreements in 38 states and 2 U.S. territories. State rules differ; for traffic stops, see 12.9.
Documents you must carry
- Under immigration law (INA 262), noncitizens aged 14 and over who remain in the United States for 30 days or longer must register. This rule must be checked again for every entry into the United States for 30 days or longer.
- Those who entered with a visa and received an I-94 record, green card and employment authorization document (EAD) holders, and people against whom removal proceedings have been initiated are already considered registered. Those who are not registered must submit Form G-325R only through their own USCIS online account.
- People aged 18 and over must carry their registration document at all times. This document may be an I-94, green card, EAD, or G-325R registration document. According to USCIS, showing the document on a phone screen or carrying a printout is also sufficient.
- Failure to carry it is a misdemeanor: for each violation, a fine of up to $5,000, up to 30 days in jail, or both.
- The penalty for knowingly failing to register when required is a fine of up to $5,000, up to 6 months in jail, or both.
- Address notification: When you move, notify USCIS of your new address within 10 days. The easiest way is through your USCIS online account. Failure to report is a misdemeanor and may also be a ground for removal. If you have a case in immigration court, you must also notify the court; see 12.3.
Registration is not a status: According to USCIS, a registration document does not grant immigration status, employment authorization, or any other right. Use the "Do I need to register?" tool on the USCIS registration page to check whether you must register.
At home and at work
- A search or seizure in a home without a warrant is generally considered "unreasonable." Exceptions recognized by U.S. courts include:
- you consent to the search;
- a search conducted during a lawful arrest;
- an emergency together with probable cause;
- the item is in plain view.
- Immigration inspections: An immigration officer may enter the following places to ask people there about their status only with a warrant or the consent of the property owner or an authorized person:
- areas of a workplace that are closed to the public;
- a home and the area around it, such as a yard;
- farms and open agricultural fields.
- If consent is given, the officer records in their report that consent was given and who gave it. If entry is denied, the officer may obtain a search warrant.
- An officer may enter public areas, such as a store or restaurant dining room, and ask questions without a warrant or consent.
If you are detained
- Notification of the consulate: Every noncitizen detained in the United States must be promptly told that they may request notification of their consulate. Türkiye is not on the list of countries where notification is mandatory regardless of the person's wishes. Therefore, for a Turkish citizen, the consulate is notified if you request it.
- Consular officials may meet with the detained citizen, contact their family, and help them find an attorney and medical services.
- For contact information for Turkish missions, see 11.1 Turkish missions in the United States and their jurisdictions.
- Finding a relative: ICE Online Detainee Locator or the ICE Detention and Reporting and Information Line (DRIL) at +1 888 351 4024 (Monday–Friday, 08:00–20:00 U.S. Eastern Time).
- For the case and bond process, see 12.3.
Do not sign a document you do not understand: A signature may mean waiving some of your rights. For example, Form I-407 means that a green card holder waives the right to appear before a judge regarding abandonment of permanent resident status; see 3.12.
Where can you report a rights violation?
- Immigration officers (ICE, CBP, USCIS): Department of Homeland Security Office for Civil Rights and Civil Liberties (CRCL), online complaint portal.
- CRCL investigates allegations of discrimination, rights violations in detention, denial of access to an attorney, and physical mistreatment.
- CRCL does not provide an individual legal remedy; it uses complaints to correct problems in DHS practices. Consult an attorney about your own case.
- DHS Office of Inspector General (OIG): +1 800 323 8603 (TTY for people with hearing impairments: +1 844 889 4357) or the online form. The line is not monitored 24/7; call 911 in an emergency.
- ICE Office of Professional Responsibility (OPR): For misconduct by ICE personnel, call +1 833 4ICE OPR, email ICEOPRIntake@ice.dhs.gov, or use the complaint form on the ICE website.
- Local and state police: For criminal misconduct such as excessive force or intentional wrongful detention, contact the FBI or the federal prosecutor's office in your area. For discriminatory practices, use the Department of Justice's civilrights.justice.gov portal.
Common mistakes
- Trying to flee, resisting an officer, or physically fighting back.
- Showing a fraudulent document or making a false statement about your name, place of birth, or citizenship.
- Misrepresenting yourself as a U.S. citizen. This is also a ground for removal for green card holders.
- Failing to carry your registration document (I-94, green card, EAD).
- Failing to notify USCIS of your address within 10 days after moving.
- Signing a document without understanding what it says.
Frequently asked questions
- I am not a citizen; do I have constitutional rights? Yes. The Fourth, Fifth, and Fourteenth Amendments refer to a "person." The Department of Justice also states that laws against police misconduct protect noncitizens as well.
- Do I have to answer an immigration officer's questions? The Constitution does not allow anyone to be compelled to testify against themselves in a criminal case, and your statements may be used against you. However, making a false statement is a crime, and the situation of a noncitizen applying for admission at the border is different. Consult an attorney about your specific situation.
- An officer wants to enter my home. For an immigration inspection, an officer may enter your home with a search warrant or with your consent. It is your decision whether to give consent.
- I was detained; will the Turkish consulate be notified? Türkiye is not a mandatory-notification country. You may request that the consulate be notified.
- Will the government give me a free immigration attorney? No. In an immigration case, you are responsible for attorney's fees. For lists of free legal-aid organizations, see 12.6.
