DUI and immigration in Colorado: a permanent-resident vs. undocumented decision guide

Your status decides the stakes — not your plea offer. A Denver crimmigration attorney walks green-card holders, undocumented community members, and DACA / TPS / pending-applicant readers through the first 48 hours and the doctrine that drives every plea decision.

Talk to a Crimmigration Attorney

A DUI arrest in Colorado is hard on anyone. For a noncitizen, it is something else — a state-court case wearing the costume of routine traffic enforcement, with a federal-immigration consequence wired underneath the plea form that the public defender is about to hand across the table. The same Friday-night stop can mean a fine and a class for a U.S. citizen and a removal proceeding for a green-card holder, an ICE hold for an undocumented worker, or a denied DACA renewal for a young person who has spent their entire adult life in this country.

This guide is built for that moment. It is the guide you reach for when the bond paperwork is on the kitchen table, when a family member is in a county jail and you cannot find out whether ICE has touched the file, when a public defender is recommending a "deferred" plea and saying "this isn't a conviction." It is not the doctrinal foundation — for the full Padilla / Pozo / Kazadi / Leocal treatment, see our standing Colorado DUI and immigration consequences page. This guide sits above that page, in the funnel and in your calendar — it is the persona-aware decision layer to read tonight before any plea, any signature, any phone call to anyone in a uniform.

The most important thing to know before you scroll: most simple Colorado DUIs are not categorical removal triggers by themselves, and most are not aggravated felonies. The stakes scale with three things — your status, the structure of any plea you take, and the specific Colorado statute of conviction. The worst decision you can make in the next 72 hours is to plead without a crimmigration analysis on the record. If you are not sure where to start, call us at (888) 746-5245 — bilingual intake, no judgment.

The short answer before you scroll

Three honest sentences before the rest of this page asks for your attention.

One. A standard, alcohol-only Colorado DUI under C.R.S. § 42-4-1301 is generally not a categorical crime involving moral turpitude (CIMT) and generally not an aggravated felony in itself — but aggravators (felony DUI on a fourth-or-subsequent offense, DUI-related vehicular assault, DUI-related child endangerment, driving-on-a-revoked-license-while-DUI, DUI-D involving a federally controlled substance under 21 U.S.C. § 802) can change that answer fast.

Two. A Colorado deferred judgment under C.R.S. § 18-1.3-102 — the kind a public defender will routinely describe as "not a conviction" — is still a conviction under federal immigration law if you plead guilty (or nolo contendere) and the court orders any form of punishment, penalty, or restraint on liberty. This is the single most-quoted misconception in Colorado DUI practice for noncitizen defendants.

Three. Your status decides the stakes. A green-card holder, an undocumented worker, and a DACA renewal applicant facing the same charge live three different cases. The rest of this page is built that way — pick your track and read.

Your status decides the stakes — read the track that matches you

This page is structured as three parallel tracks plus a Colorado-specific overlay. Read the track that matches your status. You do not need to read the others. That is a deliberate editorial choice and it is also the right legal one: a green-card holder's calendar and an undocumented worker's calendar are different in the first 48 hours, and walking through someone else's risk catalog while you are trying to make your own decisions is not useful.

• Track A — Lawful permanent residents (green-card holders). Skip to Track A.
• Track B — Undocumented community members. Skip to Track B.
• Track C — DACA / TPS / pending-application holders. Skip to Track C.

If you are family or a friend trying to figure out which track applies to someone else, the gating question is almost always what immigration document, if any, does this person hold? — green card, DACA approval notice, TPS letter, pending I-485 receipt, or none of the above. Each answer routes to a different track below.

After the tracks comes a Colorado-specific overlay that applies to everyone — the statutory ladder, the deferred-judgment trap, the Colorado Padilla-progeny doctrine that makes your defense lawyer's failure to advise you about immigration consequences a constitutional defect.

Track A — If you are a lawful permanent resident (green-card holder)

You are an admitted noncitizen. The federal screen that matters most for you is deportability under INA § 237 / 8 U.S.C. § 1227 — the grounds on which someone already admitted to the United States can be placed in removal proceedings. The screen that matters second-most is inadmissibility under INA § 212 / 8 U.S.C. § 1182, which can be triggered at a port of entry the next time you travel abroad and try to come home. A Colorado DUI plea can implicate either or both, depending on the elements of the offense and the structure of the plea.

The good news, before the rest of this section asks for your attention, is that the answer for most green-card holders facing a standard alcohol-only first-offense DUI is not catastrophic on the conviction itself, provided the plea is structured with crimmigration analysis in advance. The bad news is that nearly every Track A failure pattern we see at this firm involves a plea entered before that analysis happened — usually a deferred, often presented as "the safe option."

What a simple Colorado DUI usually means for your green card

For a first-offense alcohol-only DUI under C.R.S. § 42-4-1301, the leading authorities cut in your favor on the headline questions:

• Is it a CIMT? Generally no. The Board of Immigration Appeals has held in Matter of Torres-Varela, 23 I&N Dec. 78 (BIA 2001), that a simple DUI lacking an aggravating knowledge element is not categorically a CIMT. The aggravated variants are a different conversation (next subsection). For the full CIMT framework, see our Colorado CIMT immigration consequences guide — that post defers its DUI-specific depth to this page and to our DUI service page.
• Is it an aggravated felony? Generally no for a simple DUI. The Supreme Court held in Leocal v. Ashcroft, 543 U.S. 1 (2004), that a Florida DUI statute lacking a mens-rea element (or requiring only negligence) does not constitute a "crime of violence" under 18 U.S.C. § 16 and therefore does not qualify as an aggravated felony under INA § 101(a)(43)(F). Again, aggravated variants are a different conversation — see below.
• Is it a controlled-substance deportability trigger? For an alcohol-only DUI, no. For DUI-D (driving under the influence of drugs), possibly yes under INA § 237(a)(2)(B)(i), if the substance involved is federally controlled under 21 U.S.C. § 802 and the categorical-match analysis from Mellouli v. Lynch, 575 U.S. 798 (2015), holds against the specific Colorado DUI-D statute of conviction. The categorical-match question is technical and fact-specific — a Colorado DUI-D conviction that does not identify the substance in its elements may not categorically match the federal ground. Flag DUI-D for your crimmigration attorney early; it is its own conversation.

None of this means a Colorado DUI plea is "safe" for a green card holder. It means the plea structure is where the case is won or lost — and that structure is exactly what most first-line plea negotiations are not built to optimize for. Hedge accordingly. Talk to a crimmigration attorney before signing anything.

Aggravated DUI variants that change the answer

The doctrine flips on the aggravators. Four Colorado DUI fact patterns shift the analysis materially:

• Felony DUI (fourth or subsequent offense). Under C.R.S. § 42-4-1301, a fourth-or-subsequent DUI / DWAI / DUI-per-se / DUI-related vehicular-homicide / DUI-related vehicular-assault offense is a class 4 felony. Felony classification matters for the aggravated-felony screen and for the realistic likelihood that the offense carries an "1 year or longer may be imposed" hook for deportability analysis. The full aggravated-felony framework lives in our Colorado aggravated felony crimmigration consequences guide — that post is where the Leocal analysis and the (F) crime-of-violence doctrine are unpacked in detail.
• DUI-related vehicular assault under C.R.S. § 18-3-205. The intent or recklessness element required to convict for DUI-related vehicular assault can supply the mens-rea content that Leocal found missing in simple DUI — implicating the (F) "crime of violence" aggravated-felony analysis. Fact-specific; circuit posture varies.
• DUI-related vehicular homicide under C.R.S. § 18-3-106. Even more serious; same general framework.
• Aggravated DUI with knowledge of a suspended or revoked license — the Matter of Lopez-Meza fact pattern. The BIA held that an aggravated-DUI statute where the defendant knew driving was prohibited supplied the moral-turpitude content that a baseline DUI lacked — making that variant a CIMT. The CIMT framework lives in our CIMT consequences guide.

If your case involves any of these aggravators, the categorical-approach analysis (which compares the elements of the Colorado statute against the generic federal definition) is the engine of the defense. It is not work that should happen for the first time at sentencing.

The naturalization trap — good moral character and the 5-year window

If you are eligible to naturalize, or close to it, a DUI in the statutory good-moral-character period creates discretionary risk that you should price in before filing the N-400.

The framework: under 8 C.F.R. § 316.10, USCIS evaluates good moral character (GMC) over a statutory period — 5 years for most applicants, 3 years for spouses of U.S. citizens. DUI is not specifically named in the regulation's conditional-bar list, which means it is evaluated under the catch-all "unlawful acts that adversely reflect upon the applicant's moral character" framing — discretionary, case-by-case, and adjudicator-sensitive.

The statutory bars under INA § 101(f) include several categorical disqualifiers. The one that occasionally surfaces in DUI fact patterns is § 101(f)(1) — "habitual drunkard" — a fact-bound determination historically applied to repeated alcohol-related conduct rather than a simple two-DUI count. A single DUI generally does not trigger this framing. The more common practical exposure is the discretionary GMC catch-all under 8 C.F.R. § 316.10(b)(3)(iii), where USCIS adjudicators routinely cite DUI convictions in N-400 adjudications — particularly where two or more fall within the 5-year statutory window.

The practical posture, hedged honestly: a DUI does not automatically bar naturalization. Delaying your N-400 to clear the 5-year (or 3-year) GMC window may be the right strategic call, particularly if a second DUI is on the record. This is the kind of decision that is much better made before a denial — and a denial in this posture can do worse than waste a filing fee, because a denied N-400 with a DUI in the discretionary GMC discussion can become the file that follows you into any future interaction with USCIS.

If you are within the GMC window or have any DUI in your history, plan the naturalization filing date with crimmigration-aware counsel rather than calendar it from the residence anniversary alone.

Reentry-after-travel inadmissibility — why a DUI plea before you travel is high-risk

A green-card holder is not always treated as someone "seeking admission" when returning from abroad. The general rule is that an LPR returning from a brief, casual, innocent trip is treated as a continuing resident — not as an arriving applicant subject to the full inadmissibility screen. But there is an exception with teeth. Under INA § 101(a)(13)(C), a returning LPR can be deemed an "applicant for admission" — and re-run through the inadmissibility screen at the port of entry — if certain criminal-history conditions are met.

That is one of the cruellest gotchas in immigration law. Translation: a green-card holder with a conviction on a triggering offense — or with admissions of conduct that could supply a §212(a)(2) inadmissibility ground — can fly back into the United States after a family trip abroad and find themselves in secondary inspection facing a removal proceeding. A pending charge alone does not categorically trigger the (a)(13)(C) screen, but in practice CBP officers exercise broad referral authority at the port of entry, and an unresolved DUI matter is a real practical risk regardless of the statutory technicality. The agent at the port of entry is not bound to give you the benefit of the doubt.

Three practical points:

• Pending charges count too for some of the inadmissibility analyses (admissions of criminal conduct without a conviction can be enough on the inadmissibility side). Do not assume "no conviction yet" is shelter.
• International travel with a pending or recent Colorado DUI plea on file is a high-risk decision that should not be made without specific crimmigration review of your record and your trip.
• Document everything before you go. If a trip is necessary, your crimmigration attorney can help you assemble the file you will hand to a port-of-entry officer if you are referred to secondary inspection.

The Colorado deferred-judgment trap

This is the trap. It catches more Colorado LPRs in DUI cases than any other doctrinal mistake.

In Colorado, a "deferred judgment and sentence" under C.R.S. § 18-1.3-102 lets a defendant plead guilty, complete court-ordered conditions, and — on successful completion — withdraw the plea and have the case dismissed. For state-court purposes, that is not a conviction. Public defenders describe it that way. The judge describes it that way. The mandatory disclosure documents describe it that way. It looks and feels like an off-ramp.

For federal-immigration purposes, it is a conviction. Under INA § 101(a)(48)(A), a "conviction" includes any case in which adjudication of guilt has been withheld where (i) a judge or jury has found the alien guilty, or the alien has entered a plea of guilty or nolo contendere, or has admitted sufficient facts to warrant a finding of guilt, AND (ii) the judge has ordered some form of punishment, penalty, or restraint on liberty. A Colorado deferred judgment satisfies both prongs. The plea is the conviction for immigration purposes, regardless of what the state file says years later.

This is the doctrinal core of the trap. The full case-citation set — Padilla v. Kentucky, People v. Pozo, Kazadi v. People, and the controlling categorical-approach treatment for Colorado — lives on our Colorado DUI and immigration consequences service page. What you need to know in the next 48 hours: a deferred is not safe by default. It might still be the right plea structure for your case after a crimmigration analysis. It is not safe to assume.

Colorado's Padilla-progeny landscape — your plea counsel has a duty to advise you

A note that often surprises green-card holders facing a plea: under Colorado law, your criminal-defense attorney has an affirmative constitutional duty to investigate and advise you about the immigration consequences of any plea offer before you take it. That duty predates the U.S. Supreme Court's decision in Padilla v. Kentucky by 23 years — the Colorado Supreme Court got there first in People v. Pozo, 746 P.2d 523 (Colo. 1987), and refined the doctrine after Padilla in Kazadi v. People, 2012 CO 73.

The doctrinal depth — the full Pozo / Kazadi / Padilla treatment, the categorical-approach mechanics, the Colorado-specific post-conviction relief framework when plea counsel failed in that duty — lives on our DUI and immigration service page. For our purposes here, two things matter. One: if your public defender or appointed counsel has not asked about your immigration status, that is itself a problem. Two: if a plea was entered without that advisement and you are now seeing the immigration consequences for the first time, there may be post-conviction relief available — but the window is not infinite and the analysis is fact-specific.

First 48 hours — LPR action checklist

Designed to be read in isolation by someone in a county-jail parking lot. Each instruction stands on its own.

1. Do not plead, do not sign, do not stipulate to anything before a crimmigration analysis. Not a deferred. Not a "lesser." Not a DWAI offered as "the safer plea." Wait.
2. Get a G-28 from a crimmigration-aware immigration attorney on file as soon as possible so that any immigration-side correspondence routes through counsel.
3. Do not travel internationally while the DUI is pending or recently resolved. Reentry-after-travel inadmissibility is the kind of gotcha you only meet once.
4. Preserve your record. Pull your full criminal history (CCIC / FBI rap sheet) and your immigration file (A-file, FOIA if needed). The crimmigration attorney will need it.
5. Document the bond conditions the court has imposed and any check-in / classes / monitoring requirements. Compliance matters.
6. If a new N-400 filing is in your plan, hold off until a crimmigration attorney has run the GMC analysis on your DUI posture. If an N-400 is already filed, talk to counsel before the next step — withdrawal, RFE response strategy, and interview posture are all decisions that benefit from crimmigration-aware input before the next USCIS touchpoint.
7. If you have not engaged crimmigration counsel yet, do it today. Call Novo Legal at (888) 746-5245 for bilingual intake. Even if you ultimately work with another firm, the first 48 hours of decision-making set the rest of the case.

Track B — If you are undocumented

You are not an admitted noncitizen. The federal screen that matters most for you in the immediate window is the ICE-detainer process at the jail of booking, not the long-arc INA grounds analysis. The doctrine still matters — it shapes any future status play, any removal-defense posture, any waiver application — but the first 24 to 48 hours are about whether you stay in the criminal-court process at all, or whether you are routed into the immigration-enforcement system before the criminal case can resolve.

The honest framing, before this section asks for your attention: Colorado law since 2019 has limited (not eliminated) jail-to-ICE cooperation. The pathways still exist. The decisions made by a family member in the first 24 hours can change the case outcome materially. And no one in the booking process is going to volunteer the information you need.

The ICE detainer risk on the booking-fingerprint hit

When someone is booked into a Colorado county jail, their fingerprints are run through state and federal databases as a routine matter. The federal hit can route the booking record to ICE. ICE may then send the jail an immigration detainer — a request that the jail hold the individual for up to 48 hours past their criminal-case release time so ICE can take custody.

The Colorado law that matters here is Colorado HB 19-1124 ("Protect Colorado Residents From Federal Government Overreach"), enacted May 28, 2019. The operative restrictions:

• County jails and other Colorado law enforcement cannot arrest or detain an individual solely on the basis of a civil ICE detainer. A civil detainer alone, without more, does not authorize a hold past the criminal-case release time.
• Probation officers are barred from sharing personal information with federal immigration authorities.
• Detained individuals must be advised of their rights when federal immigration agents seek to interview them — including the right to decline the interview and the right to consult an attorney.
• Federal-judge warrants are a carve-out. A jail may still assist with the execution of a warrant issued by a federal judge or magistrate. The civil-detainer limitation does not extend to those warrants.

That is real protection. It is not total. Jail policies vary by county; cooperation patterns shift with state and federal administrations; and the carve-out for federal-judge warrants means that an individual flagged by ICE through a more aggressive process can still be detained even under HB 19-1124.

The practical first-48-hour framing: assume the detainer process may attach, plan accordingly, and let counsel run the case rather than calling federal agencies directly. Calling ICE to "ask if there is a detainer" can surface a status question that had not yet been investigated. The right move is to engage counsel and let counsel make those calls.

Jail-to-ICE transfer pathways and what families can do

In order of priority, in the first 24 to 48 hours:

• Bond out before any detainer attaches if at all possible. Once criminal-case bond is posted and the individual is released, the leverage of any pending detainer drops materially. Posting bond fast is the single highest-leverage move a family can make in this window.
• Get a G-28 from an immigration attorney on file at the jail and (separately) at the ICE office that covers the facility. The G-28 is the formal entry of appearance and is the document that gets ICE to route communications through counsel rather than directly to the detained individual.
• Locate your loved one in the ICE Online Detainee Locator System at any time. The locator does not always reflect detentions immediately but checking it periodically gives you a baseline.
• If the individual is transferred to a federal immigration facility — including the GEO-operated facility in Aurora — the case shifts from county criminal posture to federal immigration posture. Counsel routing changes. Visiting hours, communication, and bond mechanics all change. An attorney who handles both criminal defense and immigration removal is the integrated answer.
• Do not sign a Stipulated Order of Removal. ICE will sometimes present this to individuals in custody as a "fast way home." It is a one-way exit from any future removal-defense relief. Wait for counsel.

Inadmissibility groundwork — how a DUI conviction sits on your future status play

Even if no detainer attaches and the criminal case resolves in state court, a Colorado DUI conviction sits on the record as inadmissibility groundwork that affects any future status play. Under INA § 212(a)(2)(A), a CIMT or a controlled-substance offense in your record can block an adjustment of status, a visa application, or any future humanitarian-relief filing. Most simple alcohol-only DUIs are not categorical CIMTs (per Matter of Torres-Varela, above) — but aggravated variants can be, and DUI-D involving a federally controlled substance under 21 U.S.C. § 802 implicates the separate controlled-substance inadmissibility ground under INA § 212(a)(2)(A)(i)(II) — subject to the same Mellouli v. Lynch categorical-match analysis that applies on the deportability side.

The petty-offense exception (sentence imposed ≤ 6 months and statutory maximum ≤ 1 year — both prongs required) can shelter some DUI fact patterns from CIMT-based inadmissibility, but the analysis is technical and the exception is not as generous as the marketing copy on the internet suggests. A standard Colorado first-offense DUI carries up to 1 year of jail under § 42-4-1301 — the maximum-penalty prong is right at the statutory line. Do not assume the exception applies without case-specific analysis.

If a trafficking-survivor fact pattern is part of how the arrest happened — for example, a DUI arrest in the context of being coerced or trafficked — there may be specific humanitarian-relief routes that change the analysis. See our T-visa eligibility guide for trafficking survivors for that framework.

Removal-defense posture if an NTA issues

If the case progresses to a Notice to Appear (NTA) and you are in removal proceedings, the relief framework that matters most for many undocumented Colorado community members with long residence and U.S.-citizen family ties is cancellation of removal for non-permanent residents under INA § 240A(b) — the relief that immigration practitioners and clients call "42B." The eligibility framework — 10 years of continuous physical presence, good moral character through the period, exceptional and extremely unusual hardship to a qualifying U.S.-citizen or LPR relative, and no disqualifying convictions — is unforgiving and demanding.

A DUI on the record sits inside that eligibility framework in two places. First, in the continuous-physical-presence analysis — a DUI conviction does not by itself break continuous presence, but it can shape the way an immigration judge views the case. Second, in the good-moral-character analysis through the qualifying period — a single DUI does not trigger a categorical GMC bar, but multiple DUIs or aggravated DUI variants create real GMC pressure under the same § 101(f)(1) framing discussed in Track A, with the more common practical risk sitting in the discretionary catch-all of 8 C.F.R. § 316.10(b)(3)(iii).

The full eligibility mechanics — including the bars, the documentation burden, the hardship standard, and the strategic posture for filing — live in our Colorado 42B cancellation of removal eligibility guide. If you are facing a possible NTA in Colorado with a DUI on the record, that guide is the right next read.

Mixed-status family custody and care-planning

This subsection is not designed to catastrophize. The realistic framing is preparation, not panic. Mixed-status families with U.S.-citizen children should have a few basic documents in place regardless of the current case posture:

• A power of attorney for school decisions and routine medical care for the U.S.-citizen children, naming a trusted adult who is not at status risk.
• A school authorization document so the named adult can pick the children up from school if a parent is unavailable.
• Updated emergency contacts at the school and pediatrician, including phone numbers that will be answered.
• Financial-access planning so the named adult or a trusted family member can pay for groceries, rent, and utilities if a parent is detained for a period of time.
• A list of important documents (birth certificates, social security cards, immigration documents, school records, medical records) and where they are kept.

These are the documents you want to have already in place. They are not a substitute for legal counsel and they do not solve the underlying immigration risk — but they reduce the chaos if a worst-case-scenario week happens, and they are also useful for ordinary life. Many families assemble these documents regardless of immigration posture.

First 48 hours — undocumented action checklist

Designed to be read in isolation by someone in a county-jail parking lot. Each instruction stands on its own.

1. Do not make statements about immigration status to law enforcement at booking or in interview. Ask for an attorney. You have the right to remain silent — use it. Specifically, do not answer questions about where you were born, when you entered the United States, or your immigration status without an attorney present.
2. Do not sign a Stipulated Order of Removal. Wait for counsel. ICE may present this as a "fast way home" — it is a one-way exit from any future immigration relief.
3. Engage a crimmigration attorney before any plea is entered. Public-defender plea acceptance without a G-28 immigration-attorney entry of appearance is a recipe for the file moving the wrong way.
4. Bond out before any ICE detainer attaches, if at all possible. Family members posting bond as fast as the system allows is one of the highest-leverage moves in this window.
5. Locate the detained person in the ICE Online Detainee Locator System and (separately) confirm with the county jail whether ICE has placed a detainer.
6. Do not call ICE directly to ask about a detainer. Let counsel make that call.
7. Get the basic mixed-status family documents in place (power of attorney, school authorization, emergency contacts, financial access).
8. Call Novo Legal at (888) 746-5245 for bilingual intake. A same-day case review with crimmigration counsel is the right first move.

Track C callout — if you have DACA, TPS, or a pending application

Shorter section. Three categories, three different rules — and a DUI in your record affects each of them in a different way.

DACA — a DUI is on the "significant misdemeanor" list that bars renewal

The 2012 DACA memo from then-Secretary of Homeland Security Janet Napolitano framed the deferred-action eligibility screen using a "significant misdemeanor" category. Subsequent USCIS DACA guidance clarified that DUI is categorically included on the significant-misdemeanor list — regardless of how Colorado classifies the offense for state-court purposes.

The practical effect: a DUI on the record at the next renewal cycle effectively bars DACA renewal. The plea-date-versus-renewal-date calendar matters. So does the question of whether there is any post-conviction-relief play (under the Colorado Pozo / Kazadi framework or otherwise) to address the conviction itself.

DACA policy posture shifts with federal-administration changes. Verify the current USCIS DACA FAQ language at the time of any decision; do not rely on guidance that may be months stale.

TPS — DUI counts toward the two-misdemeanor disqualifier

Temporary Protected Status has a different and unforgiving disqualifier. Under 8 U.S.C. § 1254a(c)(2)(B)(i), an applicant is ineligible for TPS if "convicted of any felony or 2 or more misdemeanors committed in the United States." DUI counts.

The practical mechanics: one DUI in your record does not categorically bar TPS. It creates GMC pressure and discretionary risk, but the two-misdemeanor cliff is what does the categorical-bar work. Two DUIs (or a DUI plus any other misdemeanor) crosses the line. That is the cliff to watch.

If you currently hold TPS and are facing a Colorado DUI charge, the conversation with your crimmigration attorney is about whether the prior record already has a misdemeanor on it. If yes, this DUI is potentially the second-misdemeanor cliff — and every plea-structure decision matters more.

Pending I-485 / N-400 / family-based petitions — a DUI plea can kill an application mid-adjudication

If you have a pending application — adjustment of status (I-485), naturalization (N-400), or a family-based petition adjudication — a DUI plea on the record can derail the case in three ways:

• Disclosure obligations. Form I-485 and Form N-400 instructions require disclosure of all arrests, charges, and convictions — including arrests that did not result in conviction, including offenses that were "expunged" or "sealed" under state law, including deferred judgments. Failure to disclose is independently catastrophic under INA § 212(a)(6)(C)(i) misrepresentation grounds. The misrepresentation case is often worse than the underlying DUI case.
• GMC adjudication. A DUI within the statutory good-moral-character window can be the basis for an N-400 denial under the discretionary GMC analysis. See Track A above.
• Adjustment-of-status interview posture. USCIS adjudicators routinely issue requests for evidence (RFEs) on criminal history, and a DUI plea entered mid-adjudication can convert what looked like a clean application into a contested one.

If a family-based petition is in the pipeline and the criminal charge is more serious — felony DUI, vehicular assault, vehicular homicide — there may be criminal-grounds waiver pathways that change the analysis. The waiver framework for criminal-grounds inadmissibility is technical and fact-specific; the broader I-601 waiver framework (including the unlawful-presence waiver context) is mapped in our Colorado I-601 waiver guide.

The structural lesson: a pending application is not a reason to delay engaging crimmigration counsel. It is the strongest argument for engaging crimmigration counsel before any plea is entered.

The Colorado-specific overlay

This section applies regardless of track. The doctrine and statutory architecture that drive every Colorado noncitizen-DUI case.

Colorado's DUI statutory ladder — DUI, DWAI, DUI-per-se, felony DUI

Colorado's DUI architecture under C.R.S. § 42-4-1301 sits on a ladder that the noncitizen reader who has never been through it may not have had to learn:

• DWAI (Driving While Ability Impaired) — the lowest rung. Generally pleaded where BAC is 0.05 to 0.079, or where impairment is alleged without a confirmed per-se reading. A lesser offense than DUI in Colorado terms — but not automatically safer for immigration purposes. The CIMT and controlled-substance analyses above apply to DWAI as well.
• DUI — the headline offense. Impairment to the slightest degree. Up to 1 year jail on first offense.
• DUI per se — a 0.08 or higher BAC. Often charged alongside DUI.
• DUI-D (drug-impaired) — DUI involving drugs rather than (or in addition to) alcohol. If the substance involved is federally controlled under 21 U.S.C. § 802 and the Mellouli v. Lynch categorical-match analysis holds against the specific Colorado statute of conviction, the independent controlled-substance deportability ground at INA § 237(a)(2)(B)(i) can be in play regardless of any CIMT analysis.
• Felony DUI — fourth or subsequent DUI / DWAI / DUI-per-se / DUI-vehicular-homicide / DUI-vehicular-assault offense. Class 4 felony. The hook for potential aggravated-felony analysis under the (F) crime-of-violence framework.

The plea offer your defender presents will often be a step down the ladder — a DWAI offered instead of a DUI, a "wet reckless" offered instead of a DUI, a deferred offered instead of a straight plea. Each step down is a different immigration-side analysis. None of them is automatically safe. The crimmigration analysis is what determines which step actually reduces immigration exposure for your specific case.

Why a Colorado deferred judgment under C.R.S. § 18-1.3-102 is still a conviction for ICE

Covered in detail in Track A. The doctrinal answer: under INA § 101(a)(48)(A), the plea + court-ordered condition is the conviction for federal-immigration purposes, regardless of whether the state file is later dismissed.

This is the most-quoted misconception in Colorado DUI practice for noncitizen defendants. If you remember one thing from this page, remember this: "It's just a deferred" does not mean "It's safe for my status." It might still be the right plea structure. It is not safe to assume.

Colorado's Padilla-progeny landscape — plea counsel's affirmative duty to advise

Colorado's Padilla-progeny doctrine — the constitutional rule that your defense lawyer has an affirmative duty to investigate and advise you about the immigration consequences of any plea — predates and survives the U.S. Supreme Court's Padilla v. Kentucky decision. The Colorado Supreme Court anchored the rule in People v. Pozo, 746 P.2d 523 (Colo. 1987), and refined it post-Padilla in Kazadi v. People, 2012 CO 73.

The full case treatment — including the post-conviction-relief framework when plea counsel failed in the Pozo / Kazadi / Padilla duty, and the categorical-approach mechanics that govern which Colorado statutes implicate which federal grounds — lives on our Colorado DUI and immigration consequences service page. For purposes of this guide: if a plea was entered without crimmigration advisement and you are seeing the immigration consequences for the first time now, there may be post-conviction relief available. The window is not infinite. Move quickly.

10th Circuit and BIA posture on DUI aggravators

The 10th Circuit, which governs federal immigration appeals from Colorado, has addressed DUI-as-crime-of-violence analysis on a fact-specific basis. No 10th Circuit decision categorically resolves Colorado felony DUI as an aggravated felony, and the better posture is that Leocal controls the baseline (simple DUI lacking mens rea is not a crime of violence under 18 U.S.C. § 16) while aggravated and intent-bearing variants remain a case-by-case fight at the BIA and circuit levels.

What this means for plea negotiations: arguments are available. The categorical-approach lineage (Mathis, Descamps, Moncrieffe) is the doctrinal machinery for arguing that a particular Colorado DUI statute does not categorically match a federal generic crime. That work belongs in the plea phase, not at sentencing or appeal. For the full aggravated-felony framework, see our Colorado aggravated felony crimmigration consequences guide.

For the broader crimmigration framework that situates DUI within the full universe of Colorado criminal-immigration overlap, see our Colorado crimmigration hub.

Immigration implications synthesis

Three cross-status truths that every track in this page shares.

Every DUI plea is a federal-immigration decision wearing a state-court costume. The plea form looks like the state-court resolution of a state-court charge. It is also — for a noncitizen — the operative document of the federal-immigration consequence. The two facts are inseparable. The defender who treats only the state-court half of that document is doing half the job, regardless of how good they are at the state-court half.

Every plea offer should be reviewed by crimmigration-aware counsel BEFORE acceptance. Not after. Not as a "second opinion if there's time." Before. The plea structure — DUI vs. DWAI vs. wet reckless vs. deferred vs. straight plea, sentence imposed vs. statutory maximum, mens-rea content of the elements, controlled-substance content of the underlying conduct — is the single most-modifiable variable in the whole case. It cannot be modified after acceptance.

Consequences scale with status and with plea structure, not with whether you "served time." A green-card holder who accepts a deferred and serves no jail can be deportable. An undocumented worker who serves a weekend in county jail may have less immigration exposure than someone who took a deferred and "thought it was nothing." Time served is one input. It is rarely the input that decides the case.

The integrated answer is a defense team that does both halves of the analysis on every case. That is what crimmigration practice means — not "we have an immigration attorney down the hall," but "the plea offer is reviewed by counsel who can run the INA-side analysis before you sign anything." That is what Novo Legal does on DUI matters for noncitizen clients.

Working with a crimmigration defense team

The structural problem with splitting "DUI lawyer" and "immigration lawyer" into two separate engagements is that the plea form gets signed before the immigration analysis gets done. By the time the immigration lawyer sees the case, the immigration-consequence-determining decision (the plea structure) has been made. Post-conviction relief sometimes exists, sometimes does not — and when it does, it is harder, slower, and more expensive than getting the plea structure right the first time.

That fragmentation is exactly what the Pozo / Kazadi / Padilla doctrine was built to address. Under Colorado law, your defense counsel has a constitutional duty to investigate and advise you about immigration consequences. That duty is not satisfied by saying "you should talk to an immigration lawyer." It is satisfied by actually advising about the specific immigration consequences of the specific plea offer — which is what an integrated crimmigration defense looks like in practice.

At Novo Legal, the crimmigration practice means one team handling both halves of the case. The plea-structure analysis is done in light of the immigration consequences before any plea is entered. The full firm — see our Colorado criminal defense practice page and our immigration defense team — is built to keep both sides of the case from being decided independently.

Why Novo Legal

Novo Legal is a bilingual, community-rooted firm built for exactly the case this page describes. Criminal defense and immigration sit under one roof — not as a referral arrangement, but as one team that handles both halves of the analysis before any plea is entered. The Colorado Pozo / Kazadi doctrine is the constitutional floor; an integrated crimmigration practice is what it actually takes to clear that floor on a noncitizen DUI case.

Bilingual intake is answered in English and Spanish. We serve clients statewide from Denver, Seattle/Kent, and Walla Walla offices. We answer the phone when families are calling from a county-jail parking lot. We do not take cases we cannot do well.

If you or someone in your family is facing a Colorado DUI as a noncitizen, the next 48 hours matter. Call (888) 746-5245 or request a same-day case review.
