Know Your Rights: What to Do During an ICE Encounter in Denver

Key Takeaways

Every person in the United States — regardless of immigration status — has Fourth and Fifth Amendment rights that apply during an ICE encounter.
You are generally not required to open your door, answer questions, or sign documents without first speaking to an attorney.
Denver has adopted policies limiting local police cooperation with ICE, but those protections have limits you need to understand.
If you or a family member has been detained, an experienced bilingual attorney may help protect your rights, your freedom, and your future legal claims — including workers’ compensation and criminal defense.

You Have Rights. Here Is What They Are.

If ICE agents are at your door right now, or if you are preparing for the possibility, this is the most important thing to know: you have constitutional rights, and they apply to you regardless of your immigration status.

The Fourth Amendment protects you from unreasonable searches and seizures. The Fifth Amendment gives you the right to remain silent. These are not gifts from the government — they are protections that belong to every person on U.S. soil. Justice is not freely given, and knowing these rights before an encounter may be the difference between staying with your family and being taken from them.

This guide was written for Denver-area residents — in plain language — so you know exactly what to do at your door, on the road, and at work.

Do Undocumented Immigrants Have Constitutional Rights?

Yes. The U.S. Constitution protects all persons within the United States, not only citizens.

The Supreme Court has consistently held that the Fourth Amendment’s protection against unreasonable searches and seizures and the Fifth Amendment’s right against self-incrimination apply regardless of immigration status. You are not required to answer an agent’s questions about where you were born, how you entered the country, or your current status. You may say:

“I am exercising my right to remain silent. I want to speak with an attorney.”

That single sentence — said clearly and calmly — is one of the most powerful legal tools available to you.

If ICE Comes to Your Home — What to Do Right Now

Do not open the door. This is not defiance — it is your legal right.

ICE agents may knock and announce themselves, but an unlocked or opened door can be treated as consent to enter. Step to the side of the door, speak through it or through a window, and ask: “Do you have a judicial warrant signed by a judge?”

What Makes an ICE Warrant Valid?

There are two types of documents ICE may carry. Only one legally requires you to open your door.

An administrative warrant (Form I-200 or I-205) is issued by ICE itself — not a judge. It does not give agents the legal authority to enter your home without your consent.

A judicial warrant is signed by a federal judge or magistrate, lists your name and address, and is issued under the authority of a court. This document does require compliance.

Ask the agent to slide the document under the door or hold it up to a window. If it is not signed by a judge, you may say: “I do not consent to your entry.” Do not open the door.

The 4 Rules to Follow at Your Door

Stay calm and do not run. Running or resisting may be used against you.
Do not open the door unless presented with a valid judicial warrant signed by a federal judge.
Do not answer questions about your birthplace, immigration status, or how you entered the U.S.
Say clearly: “I am exercising my right to remain silent. I want an attorney.”

If ICE Stops You on the Road or at a Traffic Stop

Being stopped while driving creates a different — and often more dangerous — situation for immigrants. A routine traffic stop can escalate quickly if you are not prepared.

If a Denver Police officer stops you, Colorado law generally requires you to provide your driver’s license, registration, and proof of insurance. You are not required to answer questions about your immigration status.

If the officer is an ICE agent or asks specifically about your immigration status, you may say: “I am exercising my right to remain silent.” Do not lie about your status, but you are not required to confirm it either.

Denver Police vs. ICE Agent — Know the Difference

Situation	What’s Required	What You Should Do
Denver Police traffic stop	License, registration, insurance	Provide documents; stay silent on immigration questions
ICE agent stops you on the street	Nothing — ask “Am I free to go?”	Ask if you’re being detained; if not, calmly leave
ICE agent in a vehicle stop	Nothing beyond basic ID in some situations	Remain silent; request an attorney immediately

If you are facing a DUI charge or criminal traffic offense, the intersection with immigration enforcement is serious. A criminal conviction — even a misdemeanor — can trigger deportation proceedings. Our team handles Denver criminal defense representation specifically for individuals navigating this dual risk. Do not face the criminal court system without an attorney who understands both sides.

If ICE Approaches You at Work

Workplaces are not automatically protected from ICE enforcement. However, agents still typically need a valid judicial warrant to enter non-public areas of a business.

If ICE enters your workplace, you have the same rights you have at home. You are not required to answer questions. You may say you wish to remain silent and speak with an attorney. Do not sign any documents — including voluntary departure forms — without legal counsel.

Can Filing a Workers’ Comp Claim Get You Deported?

This is one of the most common fears we hear from injured workers in Denver, and it deserves a direct answer.

In Colorado, undocumented workers are generally entitled to workers’ compensation benefits under state law. Filing a workers’ comp claim does not automatically notify ICE or trigger an immigration investigation. Attorney-client privilege also protects the communications between you and your lawyer.

That said, the intersection of workers’ comp and immigration enforcement is genuinely complex, and the stakes are high.

Does Denver Police Cooperate with ICE?

Denver has adopted policies that generally limit Denver Police Department officers from honoring ICE detainer requests or assisting with civil immigration enforcement. The city has taken steps toward a “sanctuary city” posture, meaning local officers are typically not supposed to ask about immigration status or hold individuals solely for ICE.

However, these protections have important limits. They do not apply if you are charged with certain serious crimes. They do not prevent federal agents from operating independently in Denver. And policies can change — what was true last year may not be true today.

Do not assume that a Denver arrest means automatic protection from ICE. If you or a family member has been arrested and you are concerned about an ICE detainer, contact an attorney immediately.

If You or a Family Member Is Detained

Every minute matters when someone is detained. Here is what to do.

What Is an ICE Detainer?

An ICE detainer (Form I-247) is a request from ICE to a local jail asking them to hold an individual for up to 48 hours beyond their scheduled release so ICE can take custody. Denver’s policies limit compliance with these requests in many cases, but a detainer may still be issued — and complied with — depending on the circumstances.

How to Locate Someone at the Aurora Contract Detention Facility

The Aurora Contract Detention Facility (operated by the GEO Group on behalf of ICE) is the primary immigration detention center serving the Denver metro area. If a family member has been taken into ICE custody, they may be held there.

You can search for a detained individual using the ICE Online Detainee Locator at ICE.gov/detainee-locator, using their full name, country of birth, and date of birth.

How Staying Silent Protects Your Future Legal Case

This is the piece that most “know your rights” guides miss — and it may be the most important section on this page.

Anything you say to an ICE agent can be used in immigration proceedings against you. But the damage does not stop there. If you are also pursuing a workers’ compensation claim, a personal injury case, or a criminal defense, statements made during an ICE encounter can surface in those proceedings, too.

Saying “I was working at that site” in response to an ICE question, for example, could complicate a workers’ comp claim. Admitting to being in a specific location could undermine a criminal defense. Remaining silent is not just an immigration strategy — it is a protection for every legal claim you may have.

Miguel Martínez has spent over 35 years as both a prosecutor and a defense attorney. He understands exactly how statements made under pressure get used against people later. That experience is what you need in your corner.

Emergency Family Plan — Steps to Take Before an Encounter Happens

Preparation is protection. If you have not yet faced an ICE encounter, now is the time to act.

Designate a trusted contact who can be called immediately if you are detained.
Prepare a child care power of attorney so a trusted adult can care for your children if you cannot.
Write down (303) 964-3200 and store it in your phone and on paper.
Keep important documents — birth certificates, medical records, school enrollment — in a secure, accessible location.
Save a digital “Red Card” to your phone’s wallet — a quick-reference card listing your rights and our phone number that you can show without speaking. (Ask our office for the downloadable version.)
Talk to an attorney now, before a crisis, so a legal plan is already in place.

Frequently Asked Questions

Can ICE enter my home without a warrant in Colorado?

Generally, no. ICE agents may not enter your home without either your consent or a valid judicial warrant signed by a federal judge. An administrative warrant (signed by an ICE official, not a judge) does not typically give agents the legal right to enter. Do not open your door without first asking to see the warrant.

Do I have to show my ID to an ICE agent?

You are generally not required to show identification to an ICE agent who stops you on the street. If you are driving, you must provide your driver’s license to law enforcement during a traffic stop. You are not required to answer questions about your immigration status in either situation.

Can I be deported if I file a workers’ compensation claim?

Filing a workers’ comp claim in Colorado does not automatically notify ICE or trigger deportation. Colorado law generally extends workers’ comp protections to employees regardless of immigration status. However, every situation is different — speaking with an attorney before filing may help you understand and protect your rights.

What happens if ICE stops me while driving?

Stay calm. Provide your driver’s license if requested by law enforcement. You are not required to answer questions about your immigration status. Say: “I am exercising my right to remain silent. I want to speak with an attorney.” Do not sign anything.

Does the Denver police cooperate with ICE?

Denver has adopted policies that generally limit local police from assisting ICE with civil immigration enforcement. However, these protections have limits — particularly if you are charged with certain crimes. Do not assume complete protection; contact an attorney if you are concerned.

Can I remain silent if an ICE agent asks where I was born?

Yes. The Fifth Amendment gives every person in the U.S. the right to remain silent. You may say: “I am exercising my right to remain silent.” You are not required to answer questions about your birthplace, how you entered the country, or your immigration status.

Do undocumented immigrants have constitutional rights?

Yes. The U.S. Constitution protects all persons within the United States. The Fourth Amendment (protection from unreasonable searches) and Fifth Amendment (right to remain silent) apply regardless of immigration status.
