Hundreds of international students and researchers at US universities have had their visas revoked this year, leading to detentions and deportation threats. Kseniia Petrova, a Harvard researcher, was detained for failing to declare frog embryos, while others face deportation for minor offenses or no stated reason. Attorneys criticize the government's actions as disproportionate and unjust, noting the lack of due process and the chilling effect on the international student community. The increased deportations are linked to a broader Trump administration immigration crackdown, with students facing financial penalties and the threat of permanent exclusion from the US.
