## Summary

US prosecutors in Boston have dropped smuggling and false statement charges against Kseniia Petrova, a Russian-born biomedical researcher at Harvard Medical School. The case ended after a judge allowed her to seek evidence for her claim that the Trump administration had pursued her vindictively; prosecutors said they considered the claim meritless but that continuing would divert resources from more substantial federal interests.

Petrova was detained at Boston airport in February 2025 after returning from France, when customs officers found frog embryos in her checked bag. She said her supervisor had asked her to bring the samples for experiments, pleaded not guilty and was released on bail in June 2025. A federal judge ruled in April that her visa had been unlawfully cancelled.
