Colorado Immigration Laws: Rights, Benefits, and Penalties

Colorado immigration laws sit on top of federal rules rather than replacing them. The state restricts how local police cooperate with Immigration and Customs Enforcement, blocks most state agencies from handing over personal data for immigration enforcement, issues driver’s licenses regardless of status, and funds health coverage and in-state tuition that federal law would otherwise deny. Federal law still controls who can work legally, who qualifies for most public benefits, and the heaviest penalties for violations. What follows is a plain summary of the rules that most often affect immigrants, their families, and the people who hire, house, or serve them in Colorado.

What Local Police and Jails Can and Can’t Do

Under HB 19-1124, signed in 2019, no Colorado law enforcement officer may arrest or detain someone solely on the basis of a civil immigration detainer from ICE.¹ A local jail cannot hold someone past their scheduled release because ICE has asked it to. Officers can still act on a warrant signed by a federal judge or magistrate, and courts can still order prisoner transfers through the usual legal process.

The same law sets rules for custodial interviews. If federal immigration authorities want to question a person in custody, the person must first be told that immigration officials are the ones seeking the interview, that they can refuse and remain silent, that they can speak with an attorney first, and that anything they say can be used against them in immigration proceedings.¹ Probation officers and probation staff are separately barred from sharing personal information with federal immigration authorities.

How the State Protects Your Personal Information

SB 21-131 bars state agency employees from disclosing personally identifying information for the purpose of federal immigration enforcement, unless federal or state law requires it or a court issues a subpoena, warrant, or order. The Department of Revenue has a tighter rule for motor vehicle records: it cannot share them with law enforcement or any government agency if the information would be used for immigration enforcement.² That restriction matters because standard driver’s license applicants submit identity documents the state would otherwise be free to share.

Driver’s Licenses Without Legal Status

Colorado began issuing driver’s licenses to undocumented residents in 2014 under the Colorado Road and Community Safety Act (SB 13-251). These “standard credentials” are open to anyone who is not lawfully present, or who is only temporarily lawfully present, in the state.³

What You Need to Apply

Applicants show proof of identity and date of birth using a passport, consular card, or military ID from their home country, unexpired or expired less than 10 years, plus proof of a current Colorado address.³ The written and driving tests are the same ones every Colorado applicant takes. The driver license fee is $34.⁴ Standard credentials are valid for three years and must be renewed in person, with a proof of address document required at every issuance including renewals.

Why a Standard Credential Isn’t Enough at the Airport

Standard credentials carry a black banner reading “Not Valid For Federal Identification, Voting or Public Benefit Purposes” and are not REAL ID-compliant.³ In May 2025, the federal government began enforcing REAL ID for boarding domestic flights and entering certain federal facilities.⁵ If you hold a standard credential and need to fly within the United States or enter a federal building, bring a valid passport or another acceptable federal ID.

Working in Colorado: Hiring Rules and Retaliation Protections

Every U.S. employer must complete a Form I-9 for each new hire, verifying identity and work authorization, regardless of the employee’s citizenship. The requirement comes from the federal Immigration Reform and Control Act of 1986.⁶ Employers examine original documents and complete Section 2 within three business days of the employee’s first day of work.⁷

Colorado layers on C.R.S. 8-2-122. The director of the Division of Labor Standards and Statistics can request documentation proving an employer’s compliance with federal verification requirements, conduct random audits, and must request records from any employer reasonably believed to be out of compliance.⁸ A separate 20-day employer affirmation requirement and state-level fines that once existed were repealed in 2016.

Colorado also protects workers from being silenced through their status. Under the state’s Wage Protection Rules, using a worker’s immigration status to negatively affect their labor rights or any labor proceeding is an unlawful act of retaliation. That includes threatening to report someone to immigration authorities to pressure them into dropping a wage claim.⁹

Health Coverage, Tuition, and Other Benefits

Federal law sets the baseline. The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 bars undocumented individuals from most federal public benefits, including TANF, SNAP, and standard Medicaid.¹⁰ Colorado cannot override that, but it has used state dollars to open up specific pathways.

Emergency Medicaid

Undocumented residents who meet Colorado’s Medicaid income and residency criteria can receive Emergency Medicaid for conditions that place health in serious jeopardy, impair bodily functions, or cause serious organ dysfunction. Covered care includes labor and delivery, dialysis for end-stage renal disease, and life-threatening emergencies such as heart attacks. It does not cover prenatal or postnatal care, follow-up visits, or routine physician appointments.¹¹

OmniSalud

Launched in 2022, OmniSalud lets undocumented residents and DACA recipients compare and enroll in health insurance plans through a secure online platform managed by Colorado Connect, a public benefit corporation owned by Connect for Health Colorado.¹² Enrollees who qualify based on household size and income can access SilverEnhanced Savings, with zero-premium plans where insurers cover 73 percent of out-of-pocket costs. The subsidies are paid by the state’s Health Insurance Affordability Enterprise, not federal dollars.¹³

In-State College Tuition Through ASSET

The Advancing Students for a Stronger Economy Tomorrow (ASSET) law lets eligible undocumented students pay in-state tuition at Colorado’s public colleges and universities. Expanded in 2022, the current rule requires attendance at a Colorado high school for at least one year before graduating, down from three, and physical presence in Colorado for at least 12 consecutive months before enrolling. Students no longer need to start college within a year of graduating.¹⁴

A Coordinating Office

HB 21-1150 created the Colorado Office of New Americans within the Department of Labor and Employment to coordinate immigrant integration work across agencies and serve as a contact point for the public.¹⁵ It does not enforce laws or deliver benefits directly.

Paying Taxes Without a Social Security Number

Undocumented individuals who earn U.S. income have a federal tax filing obligation. The IRS issues Individual Taxpayer Identification Numbers (ITINs) so that people who cannot get a Social Security number can still file. To receive an ITIN, applicants submit Form W-7 with a valid federal income tax return attached; the IRS will not assign an ITIN before a return is filed unless a narrow exception applies. ITIN holders can claim certain tax benefits, including the child and dependent care credit and the credit for other dependents. The Tax Cuts and Jobs Act of 2017 limits ITIN renewals for spouses and dependents to situations where they are claimed for an allowable tax benefit or file their own return.¹⁶

Housing Discrimination Rules

The federal Fair Housing Act protects every person in the United States, regardless of immigration status, from housing discrimination based on race, color, national origin, religion, sex, familial status, and disability. Immigration status is not itself a protected class, but HUD has made clear that screening tenants based on citizenship or immigration status can violate the Act’s ban on national origin discrimination. A landlord who asks only certain applicants about status, or uses immigration questions as a pretext to exclude people of particular national origins, risks a federal complaint.

Landlords can request documentation and run background checks, but the procedures must be the same for everyone. Threatening to report a tenant to ICE in retaliation for filing a housing discrimination complaint is itself a federal violation.

If You’re a Crime Victim: U-Visa Certification

Noncitizen crime victims who cooperate with law enforcement may be eligible for a U nonimmigrant visa, which provides temporary legal status and work authorization. The applicant must have suffered substantial physical or mental abuse from the crime, must have information about the criminal activity (or have a parent or guardian who does, if the victim is under 16 or has a disability), and must be helpful or likely to be helpful to the investigation or prosecution.¹⁷ A certifying law enforcement agency must sign Form I-918, Supplement B, confirming cooperation.

Penalties That Can Apply

The penalties fall into two very different buckets.

For Employers

An employer that knowingly hires unauthorized workers faces federal civil fines that climb with repeat offenses. The base statutory range runs from $250 to $2,000 per unauthorized worker for a first offense, $2,000 to $5,000 for a second, and $3,000 to $10,000 for subsequent violations.¹⁸ Those base amounts are adjusted upward for inflation each year, so actual assessments today are substantially higher. An employer convicted of a pattern or practice of hiring unauthorized workers may face up to six months in prison.¹⁹ Colorado’s state verification statute authorizes audits and document requests but no longer sets state-level fines, since the earlier penalty provisions were repealed in 2016.⁸ The real financial exposure is federal.

For Individuals Using False Documents

Using someone else’s personal identifying information to obtain a government-issued document is a class 2 misdemeanor in Colorado, punishable by up to 120 days in jail. If the conduct involves forging or altering a document, it rises to a class 4 felony with significantly steeper penalties.²⁰ A person who receives public benefits or in-state tuition they were not eligible for may also be required to repay them.
