Judge Rules Visa Cancellation of Harvard Scientist Improper
A U.S. District Court judge has ruled that a customs officer improperly canceled the visa of Kseniia Petrova, a Russian-born scientist and Harvard University researcher, who was charged with smuggling frog embryos into the U.S. The judge stated that Customs and Border Protection officers exceeded their authority, as they cannot cancel visas for suspected smuggling of biological samples. Petrova, who was detained and later released, has returned to her research at Harvard. The case has drawn attention from the scientific community, concerned about its implications for recruiting foreign scientists.
