Overview

  • Kseniia Petrova, a Russian-born Harvard researcher, was charged with smuggling undeclared frog embryos into the U.S., escalating her legal troubles.
  • The charge, filed months after her February detention, carries a potential sentence of up to 20 years in prison and a $250,000 fine.
  • Petrova’s visa was revoked at Boston Logan Airport after Customs and Border Protection officers discovered the biological samples in her luggage.
  • Her attorney argues the criminal charge is baseless and aims to justify deportation efforts, while her mentor says the samples were harmless and warranted only a minor penalty.
  • Petrova, who fled Russia over anti-war activism, fears imprisonment or worse if deported; a bail hearing is scheduled for May 28 as she contests her removal.
