A ruling from the Board of Immigration Appeals (BIA) of the United States Department of Justice changes the game for thousands of Cubans applying for permanent residency: admitting to a USCIS officer that they have consumed or possessed controlled substances may be enough to deny them the green card, even if they have never been criminally convicted.
The decision, known as Matter of Mendez Maldonado, 30 I&N Dec. 62 (BIA 2026) and issued on September 22, overturns two precedents that had been protecting immigration applicants for decades: Matter of J- (BIA 1945) and Matter of K- (BIA 1957), which were in effect for 81 and 69 years, respectively.
Under those previous regulations, a USCIS officer was required to explain to the applicant the legal elements of the offense — its precise statutory definition — before any statement could be used against them to declare them inadmissible. That guarantee no longer exists.
Now, according to the analysis by the specialized law firm Novo Legal regarding the ruling, "a USCIS officer may question a foreign national about past conduct during a sworn interview, and the resulting statements are valid for purposes of inadmissibility as long as they were made voluntarily and the applicant received fundamentally fair process."
The warning from immigration specialists is clear: "Do not attend a USCIS interview without hiring legal counsel, and do not answer questions about past behavior without understanding what those questions are intended to elicit. What previously required the officer to caution you, no longer does."
The case that set the precedent involves a Mexican citizen who, during his adjustment of status interview in Tucson, Arizona, admitted under oath to having purchased cocaine on the street, consumed it at home and in other places, used it monthly for two years, and had been arrested for that reason.
The immigration judge declared him inadmissible in 2019 under section 212(a)(2)(A)(i)(II) of the Immigration and Nationality Act (INA), and the BIA upheld that decision by dismissing the appeal, using the case to eliminate historical precedents.
What does this mean for Cubans with the Adjustment Act?
The impact on Cubans applying for permanent residency under the is direct.
This law exempts applicants from the public charge inadmissibility ground, but does not protect them from the drug-related grounds established in the INA.
Anyone who acknowledges during the interview for the I-485 form that they have used or possessed any controlled substance—including marijuana, even if it is legal in the state where they reside—may be deemed inadmissible.
Marijuana remains a Schedule I controlled substance under U.S. federal law, and admitting its use to USCIS may result in inadmissibility regardless of what state law says.
The only waiver available under section 212(h) of the INA is extremely limited: it only covers the simple possession of up to 30 grams of marijuana on a single occasion, and it does not apply to cocaine or any other substance.
The decision also affects those applying for citizenship using the N-400 form, as sworn admissions in that process are likewise subject to the new rule.
In addition, the BIA noted in a footnote that its reasoning also applies to statements regarding crimes of moral turpitude under section 212(a)(2)(A)(i)(I) of the INA, meaning the scope of the ruling extends beyond the realm of drug offenses.
This ruling is the eighth precedent that the BIA has issued in four weeks in favor of the government, amidst the tightening of immigration policies under the Trump administration, and the second during this period that overturns long-standing precedents. USCIS has also tightened its adjustment of status interviews in 2026, with more detailed questions about the applicant's history.
