Federal Judge Slams CBP Over Harvard Researcher Visa Cancellation Case
A federal judge has ruled the U.S. unlawfully canceled a Harvard researcher’s visa, escalating scrutiny on immigration enforcement tied to minor customs violations.
The decision centers on Kseniia Petrova, a Russian-born scientist stopped at Boston Logan Airport with frog embryo samples, triggering a visa cancellation and detention that stretched across multiple states.
According to the Associated Press, U.S. District Judge Christina Reiss found Customs and Border Protection exceeded its authority, ruling the visa revocation was “arbitrary and capricious” and not legally justified by the alleged customs issue.
The complication is the case is not over. Petrova still faces federal smuggling charges, meaning her immigration status—and potential path to remain in the U.S.—remains uncertain despite the ruling.
“The undisputed facts reveal that Ms. Petrova’s visa was impermissibly canceled,” Reiss wrote.

The broader impact is already emerging. Immigration attorneys say the ruling draws a sharper legal boundary around when federal agents can revoke visas, a key issue in future citizenship and residency disputes involving administrative actions versus criminal findings.
For universities and employers, the case signals potential risk. According to reporting, the scientific community is watching closely amid concerns it could affect recruitment of foreign researchers and the stability of visa protections tied to employment.
What happens next will likely unfold in federal court, where the criminal case and any immigration proceedings could test how far this ruling extends beyond one researcher.
The outcome may shape how similar disputes are handled nationwide.
