CBP Visa Cancellation Checked

A federal judge in Vermont just said a Customs and Border Protection officer could not simply cross out a Harvard researcher’s visa at the airport and treat that as the end of the story. Judge Christina Reiss ruled on April 8, 2026 that the agency acted outside its legal authority when it canceled Kseniia Petrova’s J-1 research visa after a luggage search at Boston Logan International Airport. (abcnews.com) The case started on February 16, 2025, when Petrova flew back to Boston from France carrying frog embryo samples for her lab at Harvard Medical School. Customs officers said she failed to declare the biological material, and one officer marked her visa canceled in her passport. (abcnews.com) That sounds like a customs case, not a visa case, and the judge focused on exactly that split. Reiss said Customs and Border Protection has limited power to cancel a visa and could not use a baggage-declaration dispute as a shortcut to wipe out Petrova’s immigration status. (wbur.org) In court, the government argued that Petrova had lied to officers and brought in prohibited material. The judge said the record showed her visa was canceled because of the frog embryo samples, and she called that cancellation “arbitrary and capricious” and beyond the agency’s statutory authority. (nbcnews.com) (abcnews.com) One detail in the ruling matters far beyond this one lab dispute. Reiss wrote that the government could not defend an unlawful visa cancellation by pointing to things that happened after the cancellation, which blocks a common bureaucratic move of making the paperwork fit later. (thecrimson.com) Petrova’s case got more serious after the airport encounter because she told officers she feared being sent back to Russia. Instead of being allowed to return to France, she was detained and later held in immigration custody in Louisiana for about four months. (abcnews.com) (thecrimson.com) The immigration fight also turned into a criminal case in Massachusetts. Federal prosecutors later charged Petrova with smuggling and false statements, which means the judge’s ruling on the visa does not erase the separate criminal case over the samples. (thecrimson.com) That is why this decision is narrower and more interesting than a simple win-or-loss headline. The court did not say airports cannot inspect luggage or punish customs violations; it said Customs and Border Protection cannot invent extra visa-canceling power when the law gives it only specific grounds and procedures. (abcnews.com) (wbur.org) Petrova has already won one other court fight tied to the same saga. NBC News reported that a Massachusetts judge ruled in December 2025 that she could return to work, and she has been back in her Harvard lab since January 2026. (nbcnews.com) The practical takeaway is that a visa stamp canceled at an airport is not always legally final. After this ruling, travelers and lawyers have a clearer argument that some port-of-entry decisions can be challenged in federal court when officers skip the limits Congress put on them.
