A federal judge in Boston postponed a Department of Homeland Security rule that would have capped F and J visas at four years and I visas for journalists at 240 days, one day before it was set to take effect. The judge issued the postponement under the Administrative Procedure Act, finding DHS relied on weak justifications and failed to properly consider the policy's impact, while litigation continues on the merits. Duration of status remains the governing framework for now, affecting roughly 1.6 million F visa holders and 500,000 J visa holders, including many international students, exchange visitors, and foreign-media representatives.
