Kseniia Petrova, a Russian-born scientist and Harvard University researcher, was released on bail after being held in federal custody since February. She was charged with smuggling frog embryos into the United States after being questioned by United States — United States Customs and Border Protection at Boston Logan International Airport upon returning from France. Petrova's visa was canceled, and she was detained by United States — United States Immigration and Customs Enforcement in Vermont and Louisiana. She filed a petition arguing her detention was unlawful and expressed fear of persecution if deported to Russia due to her opposition to the invasion of Ukraine. A federal judge, Christina Reiss, ruled that the immigration officers' actions were unlawful and that the embryos were non-hazardous. Magistrate Judge Judith Dein approved her release on bail with travel restrictions. Petrova's attorney, Gregory Romanovsky, stated that she is considering her options for staying in the United States, as her colleagues at Harvard University emphasize the irreplaceable nature of her cancer research expertise.
