A lawsuit that could test the limits of the Trump administration's power to detain visa holders, including students and scholars, is poised to go before a federal judge.
U.S. District Court Judge Christina Reiss will hear arguments May 14 in the case of a Harvard scientist from Russia who alleges the Trump administration wrongfully detained her.
U.S. Customs and Border Protection canceled Kseniia Petrova's visa in February after she failed to declare scientific samples when she returned to Boston from France, and officers turned her over to ICE. Her attorney argues that CBP's actions were "arbitrary and capricious" and her detention illegal.
The Trump administration says it acted within its authority. Petrova "was lawfully detained after lying to federal officers about carrying substances into the country," Homeland Security said in a statement.
Here's what to know about Petrova's case.
