Based on the context provided, it appears Rumeysa Ozturk, a Turkish PhD student with a valid F-1 student visa at Tufts University, was unlawfully detained by federal immigration agents. Despite complying with visa requirements, she was arrested without charges and transferred across state lines to an ICE detention facility in Louisiana. This raises serious concerns about due process violations and overreach in immigration enforcement against international students. I urge you to investigate this incident and ensure Ozturk's constitutional rights are protected. As a lawful visa holder pursuing her education, she should not face such harsh treatment without justification. Her academic work and freedom of expression on political issues do not constitute legitimate grounds for revocation of visa status and detention. Please take action to secure Ozturk's prompt release and restoration of her student visa so she can continue her studies at Tufts University without further disruption from unlawful enforcement actions.
