A federal judge in Boston warned the administration against changing the immigration status of students and academics who sued, saying they may seek immediate relief if the government attempts to alter visas. U.S. District Judge William Young, who previously found the government illegally targeted protesters, unsealed internal DHS memos showing arrests recommended on the basis of campus speech and social‑media activity. The ruling and documents center on Columbia‑area activists and international scholars; the court order creates a real‑time judicial check on federal enforcement actions tied to campus protests.
