ICE Detains Wisconsin Green Card Holder Over 2014 Cannabis Conviction

Detention Based on State Cannabis Offense from 2014

ICE detained the Wisconsin resident on May 24, 2026, invoking a 2014 state cannabis conviction as the legal basis for initiating removal proceedings. The individual holds lawful permanent resident status—commonly known as a green card—and has resided in Wisconsin for more than a decade. ICE's Milwaukee field office executed the detention, according to Urban Milwaukee reporting on the case.

Under the Immigration and Nationality Act, controlled substance convictions render noncitizens deportable even when the underlying conduct is legal under state law. This includes state-level cannabis offenses. Cannabis remains a Schedule I controlled substance under the Controlled Substances Act, and federal immigration law doesn't recognize state legalization statutes or subsequent expungements in most circumstances. Wisconsin decriminalized possession of small amounts of cannabis in certain municipalities, but state law still classifies most cannabis offenses as criminal violations.

The 2014 conviction occurred before Wisconsin's limited medical cannabis legislation and before several municipalities adopted local decriminalization ordinances. The specific charge hasn't been disclosed. Was it possession? Distribution? Cultivation? ICE typically initiates removal proceedings against green card holders when a conviction meets the statutory definition of an aggravated felony or involves a controlled substance, even if the sentence was probation or a fine.

Federal Immigration Law Treats Cannabis as Deportable Offense

Federal immigration statute Section 237(a)(2)(B)(i) of the INA makes any noncitizen convicted of a controlled substance offense deportable, with no exception for state-legal cannabis. The provision applies retroactively to convictions that occurred before state legalization measures took effect. Courts have consistently held that state expungements and pardons don't eliminate the immigration consequences of a cannabis conviction unless the conviction is vacated on substantive or procedural grounds unrelated to rehabilitation.

The U.S. Supreme Court affirmed this framework in Mellouli v. Lynch (2015), narrowing the deportation ground to offenses involving federally controlled substances, but subsequent circuit court rulings have interpreted that holding to still encompass cannabis offenses. The Seventh Circuit, which covers Wisconsin, hasn't issued a published opinion directly addressing whether state-legal cannabis convictions qualify as deportable offenses under Mellouli. District courts in the circuit have consistently applied the federal controlled substance schedule without reference to state law.

Immigration attorneys in Wisconsin estimate that several dozen green card holders in the state face potential removal proceedings due to cannabis convictions predating local legalization efforts. Advocacy groups including Voces de la Frontera and the American Immigration Lawyers Association's Wisconsin chapter have documented cases in which ICE detained individuals years after their underlying convictions, often during routine check-ins with immigration officials or following arrests for unrelated offenses.

Implications for Green Card Holders in Legalized States

The detention underscores the ongoing conflict between state cannabis legalization and federal immigration enforcement, particularly for the estimated 9 million lawful permanent residents nationwide. Green card holders convicted of state cannabis offenses face deportation risk even in states with adult-use legalization. Even when the conviction resulted in no jail time. The risk persists regardless of how much time has passed since the offense.

Wisconsin hasn't enacted adult-use legalization, but neighboring Illinois and Michigan have, and several Wisconsin municipalities have decriminalized possession. The state legislature passed a limited medical cannabis bill in 2024, but the program doesn't provide immigration relief or expungement pathways for prior convictions. Federal immigration law doesn't recognize state medical cannabis programs as a defense to deportability.

Immigration advocates have urged Congress to pass the SAFE Banking Act or similar legislation that would create a safe harbor for noncitizens with state-legal cannabis convictions, but no such provision has been enacted. The Biden administration issued prosecutorial discretion guidance in 2021 directing ICE to deprioritize cases involving minor cannabis offenses, but the guidance is nonbinding and doesn't prevent field offices from initiating removal proceedings.

The detained individual will appear before an immigration judge in the Chicago Immigration Court, which has jurisdiction over Wisconsin cases. If the judge orders removal, the individual may appeal to the Board of Immigration Appeals and, in limited circumstances, to the Seventh Circuit. Legal representation significantly increases the likelihood of relief, but immigration proceedings don't guarantee appointed counsel for noncitizens who can't afford an attorney.
