What Is ICE
U.S. Immigration and Customs Enforcement (ICE) is a federal law enforcement agency inside the Department of Homeland Security, created in 2003. Its officers can question, detain, and arrest people, but most of their power comes from civil immigration law, which runs on different rules than a police arrest for a crime. Knowing which rule applies tells you what an officer can do at your door, on the street, and at work.
Key facts
- ICE calls its officers “federal law enforcement officers,” and a federal law lists their arrest powers (8 U.S.C. 1357).
- ICE held 65,765 people on July 11, 2026. 70.6% had no criminal conviction (TRAC).
- Local police deals to enforce immigration law grew from 135 to 2,589 since December 2024 (ICE).
- ProPublica counted more than 170 U.S. citizens held by immigration agents in nine months of 2025.

If ICE Comes to Your Door, Car, or Job
What you should do depends on where you are and what paper the officer has. The steps below follow the federal rules for immigration officers and the guidance of immigrant legal groups. This is general information, not legal advice, and none of it asks you to resist an officer physically.
What to do, by situation
Open the one closest to yours. Everyone in the United States has the right to stay silent, citizen or not.
ICE officers are knocking at my door
- You do not have to open the door. Talk through it, or step outside and close the door behind you.
- Ask whether they have a warrant signed by a judge, and ask them to slide it under the door or hold it to a window.
- Check the top and the signature. A judicial warrant names a court and is signed by a judge. Forms I-200 and I-205 are signed by an immigration officer.
- If officers come in anyway, do not resist. Say clearly, "I do not consent to this search," then stay quiet and write down names and badge numbers.
Federal rules say an officer needs a warrant or consent to enter a home to question the people inside (8 CFR 287.8(f)). A May 2025 ICE memo claims an I-205 allows forced entry for someone with a final removal order, and that memo is being challenged in court. See the section on the memo below.
An immigration officer stops me on the street or in a car
- Ask, "Am I free to go?" If the answer is yes, walk away calmly.
- You can stay silent about where you were born and your immigration status. Say, "I choose to remain silent."
- Do not carry or show false papers, and do not lie. Silence is legal; a false statement can be a crime.
- If you have valid papers that show lawful status, you may choose to show them. Adults with green cards and some visas must carry proof of status under federal law.
Officers may briefly detain someone only with "a reasonable suspicion, based on specific articulable facts," that the person is in the country unlawfully (8 CFR 287.8(b)(2)). The carry rule for registered noncitizens is 8 U.S.C. 1304(e). The Supreme Court let broad stops in Los Angeles continue in September 2025 while the case goes on.
ICE comes to my workplace
- Officers can go anywhere the public can, like a lobby or a sales floor.
- To enter areas the public cannot, like a kitchen, warehouse, or office, they need a warrant or the consent of the person in charge.
- You can stay silent and ask for a lawyer. Do not run.
- If you are a manager, you can ask to see the warrant and read which areas it covers.
The same rule that protects homes covers "the non-public areas of a business" and farms (8 CFR 287.8(f)(2)). A separate audit of I-9 employment forms needs no warrant, ICE says.
I have an immigration court hearing
- Go to your hearing. Missing it can lead to an order of removal without you there.
- Talk to a lawyer before the date. Many legal aid groups watch courthouses and can advise you on arrests there.
- Bring copies of your papers and leave the originals with someone you trust.
- Give a family member the ICE detainee locator website and your A-number in case you are held.
ICE made arrests at and near immigration courts in 2025. In March 2026, the Justice Department told a federal judge that the May 2025 courthouse policy it had cited "does not and has never applied" to immigration courts (NBC News).
I am a U.S. citizen and an officer does not believe me
- Say clearly that you are a U.S. citizen. You do not have to carry proof, but a passport card or REAL ID can end a stop faster.
- Stay calm, keep your hands visible, and do not physically resist, even if you are sure the stop is wrong.
- Ask for the officer's name and agency, and write down the time and place.
- After you are released, talk to a civil rights lawyer. You can file a complaint and, in some cases, a claim for damages.
ICE cannot deport a citizen, but immigration officers can arrest anyone for a federal crime committed in their presence (8 U.S.C. 1357(a)(5)). Most citizens ProPublica found held in 2025 were accused of interfering with officers.
Someone I love was taken by ICE
- Search the ICE Online Detainee Locator with their name and country of birth, or their A-number.
- Call a legal aid group from the directory above, and the MigraWatch hotline.
- Gather their papers: ID, any immigration forms, proof of how long they have lived here, and records of family ties.
- Do not pay anyone who promises a fast release unless they are a licensed lawyer or an accredited representative.
ICE says "Everyone in ICE custody is accounted for" and points families to its Online Detainee Locator System or a local field office (ICE FAQ).
Is ICE Law Enforcement?
Yes. ICE agents are federal law enforcement officers, and they can arrest people. ICE’s own answer to the question is direct: “ICE officials are federal law enforcement officers” (ICE). The agency has two main arms. Enforcement and Removal Operations (ERO) finds, detains, and deports people under civil immigration law. Homeland Security Investigations (HSI) runs criminal cases, from drug smuggling to human trafficking, with more than 8,700 employees (ICE).
The confusion online comes from what kind of law ICE mostly enforces. Being in the country without permission is usually a civil violation, not a crime, so most ICE arrests are civil arrests for a deportation case. That is why ICE can arrest someone on a form its own officers sign, and why the protections people know from criminal cases, like a free lawyer, do not all apply.
Can ICE Arrest You Without a Warrant?
Yes, in some situations. ICE does not need a judge’s warrant to arrest someone on the street, at work, or in a car, but federal rules require a warrant or consent to enter a home. A 2025 ICE memo claims one exception, covered below. ICE puts it plainly: “ICE does not need judicial warrants to make arrests” (ICE). Most ICE arrests use forms its own officers sign, which the next section compares.
What the law lets an immigration officer do without any warrant, in the statute’s own words (8 U.S.C. 1357(a)):
- “Interrogate any alien or person believed to be an alien as to his right to be or to remain in the United States.”
- Arrest a noncitizen if the officer “has reason to believe” the person is here unlawfully “and is likely to escape before a warrant can be obtained.”
- Arrest anyone for a federal crime committed “in the officer’s or employee’s presence.”
The regulations add the limits. An arrest needs “reason to believe” the person is here unlawfully, officers must get a warrant unless the person is likely to escape first, and at the arrest they must identify themselves and state the reason “as soon as it is practical and safe to do so” (8 CFR 287.8(c)).
Why Do ICE Agents Wear Masks?
ICE says its officers wear masks to protect themselves and their families from being identified online. The agency’s answer: “ICE law enforcement officers wear masks to prevent doxing, which can (and has) placed them and their families at risk.” It adds that officers carry badges and credentials and “will identify themselves when required for public safety or legal necessity” (ICE).
No federal law requires an immigration officer to show their face. The regulation requires an arresting officer to identify themselves as an officer and state the reason for the arrest “as soon as it is practical and safe to do so” (8 CFR 287.8(c)). The VISIBLE Act, filed in July 2025 as S. 2212 and H.R. 4667, would require immigration officers to display their agency and a name or badge number and would bar most face coverings. It has not left committee (bill text).
California tried a state ban, and a federal judge blocked the mask part. Governor Newsom signed the No Secret Police Act, SB 627, on September 20, 2025, banning federal and local officers from wearing ski masks and similar face coverings on duty starting January 1, 2026. On February 9, 2026, a federal judge blocked the mask ban for federal agents because it did not also cover state officers, while declining to block a separate law, the No Vigilantes Act (SB 805), that requires federal officers to display identification (Sen. Scott Wiener). The Ninth Circuit then blocked the identification rule for federal officers. On April 22, 2026, it held that the rule likely “attempts to directly regulate the United States in its performance of governmental functions” (opinion), and on October 14 it ordered the trial court to enter a preliminary injunction (opinion). The Legislature passed SB 1004 to extend the ban to state officers on August 28, 2026 (Sen. Scott Wiener), and Governor Newsom signed it on September 29, 2026 (Governor’s office).
The judge who blocked the California mask ban still found that masks work against public trust. “The presence of masked and unidentifiable individuals, including law enforcement, is more likely to heighten the sense of insecurity for all,” the ruling said, as quoted by the bill’s author (Sen. Scott Wiener). If an officer is masked, you can still ask for a name, agency and badge number, write down what you see, and ask to see a warrant. Do not physically resist.
Warrants, Detainers, and What Each One Allows
The paper an officer holds decides what they can do. Most ICE paperwork is signed by ICE, not a judge, and most of it authorizes an arrest, not a search. Here is how the main documents compare.
ICE warrants and detainers compared
Source: 8 U.S.C. 1357; 8 CFR 287.7 and 287.8; ICE Immigration Enforcement FAQ; Brennan Center
A detainer is a request, not a command. The regulation says a detainer “is a request” that a jail tell ICE before it releases someone, and that the jail may hold the person no more than 48 hours, not counting weekends and holidays (8 CFR 287.7). Whether a jail honors those requests is the heart of the fight over sanctuary policies.
The 2025 Memo on Entering Homes
Most know-your-rights guides say an ICE form can never get officers into your home. ICE now says it can, in one situation. On May 12, 2025, ICE’s acting director signed a memo telling officers they may force their way into a home to arrest a person with a final order of removal, using a Form I-205 (Brennan Center). Whistleblowers gave the memo to Congress in January 2026.
The two positions are clear. The Department of Homeland Security says people served with an I-205 have already had “full due process and a final order of removal” from an immigration judge. The Brennan Center and other critics answer that a warrant signed by the agency doing the arrest is not the independent judge the Fourth Amendment requires, and the Supreme Court has held that “physical entry of the home is the chief evil” the amendment guards against (Payton v. New York, 1980). Our 4th Amendment explainer covers that history.
The memo is being tested in court. Two Massachusetts groups sued on January 30, 2026, and no ruling had been issued as of September 2026 (Civil Rights Litigation Clearinghouse). Until a court rules, the safe course is the same either way: do not open the door, ask to see the warrant, and do not resist if officers enter.
Can ICE Arrest U.S. Citizens?
ICE cannot deport a citizen, but immigration agents can and do hold citizens. The law lets immigration officers arrest anyone for a federal crime committed in front of them, and they can detain someone briefly while they check a claim of citizenship. The government does not count how often this happens. ProPublica tried, reviewing court records, local news, and social media in English and Spanish, and found more than 170 cases in the first nine months of 2025 (ProPublica).
Most citizens ProPublica found were held after being accused of getting in agents’ way, and charges often never followed.
| Category | Value |
|---|---|
| Accused of assaulting or impeding officers | 130 |
| Held after agents questioned their citizenship | 50 |
| Charges never filed or dismissed | 50 |
| Children held | 20 |
| Held more than a day with no call to family or a lawyer | 20 |
Source: ProPublica, October 16, 2025. Approximate counts from reported cases; groups overlap, and ProPublica calls the tally incomplete.
DHS disputes the framing. “We don’t arrest US citizens for immigration enforcement,” spokesperson Tricia McLaughlin told ProPublica. The difference between the two accounts is the reason for the arrest: citizens are not arrested for being in the country unlawfully, but they are arrested while agents check their status or on charges of interfering.
The Supreme Court weighed in on street stops in September 2025. It paused a Los Angeles order that had barred agents from stopping people based on race or ethnicity, speaking Spanish, the kind of job they appear to do, or where they are, like a car wash or a Home Depot. Justice Brett Kavanaugh wrote that “apparent ethnicity alone cannot furnish reasonable suspicion” but can be “a relevant factor,” and that citizens stopped “may promptly go free.” Justice Sonia Sotomayor, writing for three dissenters, answered: “We should not have to live in a country where the Government can seize anyone who looks Latino, speaks Spanish, and appears to work a low wage job” (Noem v. Vasquez Perdomo).
How Local Police Became ICE Partners
Your local sheriff or police officer may now have ICE’s power to question and arrest people about their immigration status. Section 287(g) of the immigration law lets ICE sign agreements that train local officers to act as immigration officers. In December 2024 there were 135 of these agreements, all inside jails. By September 26, 2026, ICE listed 2,589 in 39 states, about 19 times as many, and most were a new kind that puts immigration powers in patrol officers’ hands.
The biggest growth came from the model that lets officers use immigration powers on routine patrols.
| Group | December 2024 | September 2026 | Change |
|---|---|---|---|
| Task Force Model (police enforce immigration law on patrol) | 0 | 1,841 | +1,841 |
| Warrant Service Officer (jail staff serve ICE warrants) | 75 | 564 | +489 |
| Jail Enforcement Model (jail staff screen and process) | 60 | 184 | +124 |
Sources: National Immigration Forum (December 2024 counts); ICE 287(g) program page, as of September 26, 2026.
The Task Force Model had no agreements at all in December 2024. It lets designated officers “enforce limited immigration authority while performing routine police duties,” ICE says (ICE). For a reader, that means a traffic stop by a local deputy can turn into an immigration arrest in a county with a task force agreement. Check your county on ICE’s list of participating agencies.
How Many People ICE Holds
ICE is holding more people than at any point in the years TRAC has tracked, and about 71 in 100 of them have no criminal conviction. Detention reached a record 70,766 in late January 2026, according to TRAC’s data as reported by Stateline.
- 65,765
- people in ICE detention on July 11, 2026
- 70.6%
- of them with no criminal conviction
- 70,766

A detention count is a snapshot of one day, not the number of people arrested in a year. Each person counted is in civil custody for a deportation case, which is why most have no conviction: being in the country unlawfully is not by itself a crime.
Where ICE Powers Stand in 2026
Several of the rules on this page changed in 2025, and most of the changes are in court. The list below gives each one’s status as of the date shown.
Where each fight over ICE's powers stands
As of October 15, 2026
- Forced home entry with an I-205 (May 2025 memo) In litigation, policy in use
Two Massachusetts groups sued January 30, 2026. No ruling as of September 2026. (source)
- Stops based on race, language, job, or location (Los Angeles) In litigation, stops allowed for now
The Supreme Court stayed the district court’s limits on September 8, 2025, while the appeal continues. (source)
- Arrests at and near immigration courts In litigation
On March 25, 2026, the Justice Department told the federal court in New York that ICE’s May 2025 courthouse memo never applied to immigration courts, after the judge had relied on it in refusing to block the arrests. (source)
- Enforcement at schools, hospitals, and places of worship Agency action, limits removed
DHS rescinded its protected-areas limits in a memo issued January 20, 2025. Under a court order since March 2025, ICE must keep the old limits at about 1,400 places of worship in 36 states. (source)
- 287(g) agreements with local police Agency action, expanding
ICE listed 2,589 agreements in 39 states on September 26, 2026. (source)
- California ban on masked officers (SB 627) Blocked by a court, mask ban on hold for federal agents
A federal judge put the mask ban on hold for federal agents on February 9, 2026, finding it discriminated against the federal government, and no party appealed. SB 1004, which adds state officers to meet that ruling, was signed September 29, 2026. (source)
- California ID requirement for federal agents (SB 805) Blocked by a court, for federal officers
The district court declined to block it in February 2026. The Ninth Circuit blocked it pending appeal on April 22, 2026, finding it "attempts to directly regulate the United States in its performance of governmental functions," and on October 14 ordered the district court to enter a preliminary injunction. (source)
- VISIBLE Act (S. 2212, H.R. 4667) Proposal, in committee
Would require immigration officers to show their agency and a name or badge number and would bar most masks. Introduced in the Senate July 8, 2025. (source)
- Detainers as requests to local jails Law, 48-hour limit
The regulation still calls a detainer a request and caps the extra hold at 48 hours. (source)

The Honest Disagreement
The fight over ICE’s powers is a fight over speed and checks. Supporters of the current approach, including DHS, argue that immigration arrests are civil, that people with final removal orders have already had their day in court, and that requiring a judge for every arrest would let people with orders avoid them indefinitely. ICE says its officers wear masks “to prevent doxing” and “will identify themselves when required for public safety or legal necessity” (ICE).
Critics, including the Brennan Center and the three dissenting justices in Vasquez Perdomo, argue that a warrant signed by the arresting agency is no check at all, that stops based partly on ethnicity will keep sweeping in citizens, and that masked officers make it hard to tell federal agents from impostors. Both sides agree on one fact that matters to readers: the rules are being set in court right now, case by case.
Not every officer in the news is ICE. Customs and Border Protection runs the Border Patrol and works at ports of entry, and it has taken part in interior operations. FBI agents, federal marshals, and local officers under 287(g) agreements may also appear. The rights on this page apply to all of them, but the paperwork and powers differ, so ask each officer which agency they are with.
Frequently Asked Questions
Are ICE agents law enforcement?
Yes. ICE says its officers are federal law enforcement officers, and federal law gives them the power to question, arrest and detain people. Most of their arrests are civil immigration arrests, not criminal ones.
Can ICE arrest you without a warrant?
Yes, in some situations. ICE says it does not need a judicial warrant to make arrests, and federal law lets officers arrest a noncitizen they have reason to believe is here unlawfully and likely to escape before a warrant can be obtained. Federal rules require a warrant or consent to enter a home, though a 2025 ICE memo claims one of its own forms allows forced entry for people with final removal orders, and that memo is being challenged in court.
Why do ICE agents wear masks?
ICE says its officers wear masks to prevent doxing, which it says has put them and their families at risk. No federal law requires immigration officers to show their faces. A California ban on masked officers was blocked for federal agents in February 2026.
Can ICE ask for my ID?
An officer can ask anyone a question, and you can decline to answer or show ID unless your state requires it during a lawful stop. People with some visas and green cards must carry proof of status by federal law. Never show false papers.
Do ICE officers have to identify themselves?
The regulation says an arresting officer must identify themselves and state the reason for the arrest as soon as it is practical and safe. It does not require an officer to show their face.
Can I sue ICE if I was wrongly detained?
Sometimes. The Federal Tort Claims Act lets people seek damages from the federal government for some wrongful arrests and injuries, starting with a written claim to the agency. Suits against individual federal officers are much harder after the Supreme Court limited them in Egbert v. Boule in 2022, so talk to a civil rights lawyer.
What You Can Do
-
Save the help numbers now. Put the MigraWatch hotline, a local legal aid number, and the ICE detainee locator in your phone, and share them with anyone who might need them.
-
Make a family plan. Decide who picks up children, who holds copies of important papers, and who has your A-number if you have one. Legal aid groups have free templates.
-
Learn the one sentence that matters at the door. “Please slide the warrant under the door.” Read who signed it before you decide anything, and remember that you do not have to open the door to talk.
-
Find out whether your county has a 287(g) agreement. Check ICE’s list of participating agencies and ask your sheriff and county commissioners how they use it.
-
Ask Congress to require a judge’s warrant for home entry. Use the letter below, which asks your representatives to end forced entry on ICE’s own paperwork. Our protest rights guide and 5th Amendment explainer on staying silent cover related rights.
