US moves to drop smuggling charges against Harvard scientist

The dismissal follows a judge’s ruling that Petrova could seek records for her selective-prosecution claim, and prosecutors said the case would divert federal resources.

  • On Tuesday, federal prosecutors in Boston moved to drop criminal smuggling charges against Kseniia Petrova, a Russian-born scientist at Harvard University, after she argued the Trump administration singled her out for prosecution.
  • Last month, a Boston judge concluded Petrova presented sufficient evidence of selective prosecution, granting her access to government records to support her claim; prosecutors had initially brought the case in May 2025.
  • While labeling the claims "meritless," prosecutors stated in a court filing that continuing prosecution would "divert significant time and attention from more substantial federal interests." US Attorney Leah Foley declined to comment.
  • Immigration authorities detained Petrova at the Boston airport in February 2025 after her visa was revoked upon returning from France; a Vermont judge later ruled the visa cancellation unlawful.
  • Petrova's lawyers argued the charges stemmed from a broader campaign by President Donald Trump's administration targeting researchers and universities like Harvard. She worked at Harvard Medical School and had pleaded not guilty.
