What to do if Immigration and Customs Enforcement comes to your home, your workplace, or stops you in public.
The Fourth Amendment (no unreasonable searches and seizures) and the Fifth Amendment (the right to stay silent and to due process) protect everyone physically present in the United States, no matter their immigration status. The Supreme Court has affirmed this for well over a century, in cases stretching from Yick Wo v. Hopkins in 1886 to Zadvydas v. Davis in 2001.
How you use those rights -- calmly, clearly, and out loud -- shapes how an encounter with Immigration and Customs Enforcement (ICE) goes more than almost anything else.
ICE usually cannot enter a home without consent or a judicial warrant. A judicial warrant is signed by a judge or magistrate, names the exact address, and is issued by a court under the rules that govern criminal search warrants. An administrative warrant -- Form I-200 (arrest) or Form I-205 (removal) -- is signed by an immigration officer, not a judge, and does not authorize entry into a private home.
If officers knock, no one has to open the door. Ask them to slide the warrant under the door or hold it to a window so you can read the names, the address, and who signed it. If it is an administrative warrant, or names someone who does not live there, you can refuse entry without opening the door.
In public, an immigration officer needs reasonable suspicion to briefly stop someone and probable cause to arrest. Ask, "Am I free to go?" If yes, you can walk away calmly. If no, you are being detained -- and the right to stay silent and to ask for a lawyer kicks in right away.
A driver stopped by ICE or Border Patrol must show license, registration, and proof of insurance. Passengers usually do not have to answer questions about immigration status or birthplace. At a fixed Border Patrol checkpoint within 100 miles of a U.S. border, agents can ask brief citizenship questions; holding you longer or searching the vehicle requires consent or probable cause.
Most workplace enforcement starts on paper, not with a raid. An I-9 audit gives the employer at least three business days' notice and happens at the employer's office. Workers do not need to be there and are not the target of the audit itself.
If ICE shows up in person, the warrant rules still apply: officers can enter public areas without a warrant, but private, non-public areas need the employer's consent or a judicial warrant. In non-public areas, workers can refuse to answer questions about immigration status and can ask, "Am I free to leave?"
Anyone in ICE custody can contact an attorney and their country's consulate -- a right guaranteed by the Vienna Convention on Consular Relations. Immigration court usually offers no court-appointed lawyer, but many nonprofits, law school clinics, and pro bono programs take removal cases for free. The sooner a lawyer steps in, the more options usually stay open.
Do not sign anything in custody without legal advice. ICE may hand you a Form I-826 (notice of rights) along with a stipulated removal order or a "voluntary departure" form. Signing can give up your hearing before an immigration judge -- including the chance to apply for asylum, cancellation of removal, or other relief that may fit facts the officer never asked about.
The most useful thing a mixed-status family can do is plan for the worst before it happens. Name a trusted person to care for the children if a parent is detained, and put it in writing with a state-law guardianship form or power of attorney. Keep certified copies of birth certificates, passports, marriage certificates, and any past immigration filings where that trusted person can reach them.
Several national groups print free Know Your Rights cards in many languages -- the ACLU, Immigrant Legal Resource Center, and National Immigration Law Center are good starting points. A wallet card that reads, in English, "I am exercising my right to remain silent. I want to speak to a lawyer," is far easier to hand an officer than to recite under stress.
