- Citation
- Petrova v. Hyde, No. 2:25-cv-00240 (D. Vt.)
- Court
- U.S. District Court for the District of Vermont
- Decided
- Release ordered May 28, 2025; merits ruling on visa cancellation, April 2026
- Judge
- Christina Reiss
- Statute
- 28 U.S.C. § 2241; immediate-custodian and district-of-confinement rules (Rumsfeld v. Padilla); Administrative Procedure Act
- Holding
- Jurisdiction was retained in the district where the petition was filed before the petitioner’s transfer; her detention was unlawful and release was ordered; and customs officers lacked authority to cancel her visa, rendering the cancellation arbitrary and capricious.
Where a habeas petition must be filed, and what happens when the government moves the petitioner after she files, are among the most consequential procedural questions in immigration habeas. Petrova v. Hyde addressed both, and added a merits holding on the limits of customs authority for good measure.
The facts
Kseniia Petrova, a researcher at Harvard Medical School, had her J-1 visa canceled at Logan Airport over undeclared frog embryos she was carrying for her laboratory. She was detained and then transferred from Vermont to a facility in Louisiana — a familiar pattern, in which detainees are moved to jurisdictions thought more favorable to the government. She had already filed her § 2241 petition in Vermont before the transfer.
The immediate-custodian problem
Under Rumsfeld v. Padilla, a habeas petition challenging present physical confinement is generally filed against the immediate custodian in the district of confinement. The government’s post-filing transfers exploit that rule: move the petitioner, and the original court arguably loses its grip. Judge Christina Reiss declined to let the maneuver work here, holding that jurisdiction was fixed in Vermont, where the petition was properly filed before the transfer. On the merits of detention, she found clear and convincing evidence that Petrova was neither a danger nor a flight risk and ordered her released as unlawfully detained.
“Jurisdiction, once it has attached, does not evaporate because the government has put the petitioner on a plane.”
The 2026 merits ruling
In April 2026 the court reached the underlying question and held that the visa cancellation itself was unlawful: customs officers lacked authority to cancel a visa on suspicion of smuggling biological samples, making the cancellation arbitrary and capricious. The detention-jurisdiction holding is the part that matters most for habeas doctrine. It sits with this archive’s other procedural entries — the venue and transfer fight in Ozturk, the “zipper clause” question in Khalil, and the broader mandamus-versus-habeas discussion — as part of the developing law on how courts keep the writ from being defeated by the simple expedient of moving the prisoner.
