Kseniia Petrova, a Russian biomedical researcher at Harvard Medical School, is currently detained by U.S. Immigration and Customs Enforcement ICE after her visa was revoked upon returning from France. The revocation stemmed from her failure to declare frog embryo samples, a violation typically resulting in a fine. Petrova fears persecution if deported to Russia due to her antiwar stance and previous arrest for protesting the invasion of Ukraine. She is awaiting an asylum hearing in May, with colleagues and legal experts criticizing the severity of her detention.
