DUI and Immigration Consequences in Illinois

The Arrest Starts Three Clocks, Not Two

A DUI arrest in DuPage County sets two deadlines running for every driver. The criminal case moves toward the courthouse in Wheaton. Separately, the statutory summary suspension of your driving privileges takes effect on the 46th day after the officer hands you the notice, whether or not anyone has convicted you of anything.

If you are not a United States citizen, a third clock is running, and it is the one most people do not know about. Federal immigration consequences can attach to an arrest, to a plea that Illinois does not treat as a conviction, and to a sentence that looks mild in criminal court. Some of them begin before your first court date.

A Standard Illinois DUI Is Usually Not a Deportable Offense

Start with the floor, because the floor is genuinely reassuring. A first, alcohol-only DUI with no injury, no drugs, and no aggravating facts is generally not by itself a ground of deportation.

The Supreme Court held in Leocal v. Ashcroft, 543 U.S. 1 (2004), that a DUI offense requiring nothing more than negligence is not a crime of violence, which means it is not an aggravated felony for immigration purposes. The Board of Immigration Appeals has separately held that ordinary DUI, including repeat DUI, is not a crime involving moral turpitude. The two categories that carry the harshest immigration consequences do not, as a general rule, capture a simple Illinois DUI.

That is the floor. It is not the ceiling, and almost everything that matters happens in the distance between them.

Court Supervision Is Not a Conviction in Illinois. It Is One Under Federal Law.

Illinois gives first-time DUI defendants a disposition that most states do not have. Under 730 ILCS 5/5-6-1, a judge may enter court supervision rather than a conviction. You complete the conditions, the case is dismissed, and no conviction is entered. For a citizen, that is often the difference between keeping a license and losing it for a year.

Federal immigration law does not recognize any of it.

The federal definition of conviction at 8 U.S.C. § 1101(a)(48)(A) has two prongs. The first is met where a judge has found the defendant guilty, or the defendant has pleaded guilty or no contest, or has admitted facts sufficient to support a finding of guilt. The second is met where the judge has ordered some form of punishment, penalty, or restraint on liberty. Illinois court supervision requires a plea or finding of guilt, and it always imposes conditions. Both prongs are satisfied.

What Turns a DUI Into an Immigration Case

Four fact patterns account for most of the serious immigration exposure that comes out of an Illinois DUI arrest. Any one of them changes the analysis completely.

The drug cases deserve particular attention because the criminal exposure and the immigration exposure diverge so sharply. A cannabis DUI may carry the same Illinois penalties as an alcohol case while producing a completely different federal result, and the same is true of charges involving other controlled substances, including validly prescribed medication. Where a second DUI is charged, the good moral character question arrives on top of the criminal enhancements rather than instead of them.

The Arrest Alone Can Cost a Visa

Everything above concerns convictions. Visa holders carry a separate exposure that requires no conviction whatsoever.

Since November 2015, the State Department has prudentially revoked nonimmigrant visas when it learns of a DUI arrest or conviction within the previous five years, under the authority at 9 FAM 403.11. Prudential means the officer is not finding you inadmissible. The officer is canceling the visa as a precaution, on the theory that a health-related admissibility question now needs answering.

This reaches people on H-1B, L-1, F-1, TN, and visitor visas who are already living and working here. Revocation generally takes effect on departure, so it does not force you to leave. What it does mean is that the visa in your passport may not work when you try to come back, and obtaining a new one can require an evaluation by a State Department panel physician. A great many people find out at the airport.

Naturalization and Green Card Applications

Good moral character is required for naturalization across a statutory period, generally the five years before filing, or three years for certain spouses of citizens. On August 15, 2025, USCIS issued policy memorandum PM-602-0188, directing officers to assess good moral character through the totality of the circumstances rather than by checking for the absence of disqualifying conduct. Officers now weigh positive contributions alongside negative conduct, and they are also instructed to look for patterns, including repeated traffic offenses.

Disclosure is where supervision cases go wrong a second time. The N-400 asks about arrests and citations, not only convictions. A DUI arrest that ended in supervision gets disclosed. So does one that was dismissed, and so does one that was expunged or sealed, because state expungement and sealing do not eliminate a conviction for federal immigration purposes. Failing to disclose can be treated as false testimony, which is a separate bar to good moral character and is routinely worse than the DUI it was meant to hide.

What Illinois Law Does and Does Not Protect

The Illinois TRUST Act, at 5 ILCS 805/15, prohibits state and local law enforcement from holding someone past their scheduled release solely on a civil immigration detainer or an administrative warrant. A detainer is a request from a federal agency. A warrant signed by a judge is a different instrument. Illinois jails are not permitted to treat the first as though it were the second, and the Illinois Attorney General’s guidance on the statute is detailed about the difference.

That protection is real, and it is narrower than people assume. Fingerprints taken at booking are shared with federal databases, which is frequently how immigration authorities learn someone is in custody in the first place. The TRUST Act constrains local agencies; it does not constrain federal ones. Reporting through 2026 has also documented Illinois agencies cooperating with federal immigration agents in ways the statute was written to prevent. Knowing what the rule says is not the same as being able to count on it.

A Bill That Would Change All of This

On June 26, 2025, the House of Representatives passed H.R. 875 by a vote of 246 to 160. The bill would amend the Immigration and Nationality Act to make a DUI conviction, or an admission to the underlying conduct without any conviction, a ground of both inadmissibility and deportability, drawing no distinction between a misdemeanor and a felony. It was referred to the Senate Judiciary Committee the next day and has remained there.

It is not law. Nothing about an existing case changed when the House voted. What it should change is how carefully a pending DUI gets handled, because a disposition that is defensible under current law may read very differently under a statute that treats every impaired driving conviction identically.

Defending a DUI When Status Is on the Line

In Padilla v. Kentucky, 559 U.S. 356 (2010), the Supreme Court held that defense counsel has a constitutional duty to advise a noncitizen client about the deportation consequences of a plea. Meeting that duty means the criminal case has to be built with the immigration picture in view from the first court date, not consulted about it afterward.

In practice, that changes what a good outcome looks like. The disposition that ends the case fastest is often the one that does the most damage. Keeping a controlled substance out of the record can matter more than reducing jail exposure. A sentence structured at 364 days can matter more than the label on the charge. A reduction to reckless driving may be worth pursuing for reasons that have nothing to do with the Illinois penalties. Sometimes the right answer is to challenge the stop, contest the testing, or litigate the summary suspension rather than accept any plea at all.

Pat Weiland spent nearly ten years as a DuPage County Assistant State’s Attorney, including service as a supervisor in the felony trial division. That experience is knowledge of how these cases are charged, evaluated, and negotiated in Wheaton. It is not influence over the people making those decisions, and any attorney who suggests otherwise is telling you something that is not true.

Protecting status is coordinated work: your immigration attorney identifies which outcomes you can survive, and we build the defense that pursues them.
