<h1>DHS proposes fixed admission periods for F and I nonimmigrant visas, replacing 'duration of status' with set terms</h1> The federal Department of Homeland Security proposes a rule to limit authorized admission and extension periods for certain nonimmigrant classifications, replacing the longstanding 'duration of status' for student (F) visa holders with fixed terms tied to program length not to exceed four years, and capping foreign media (I) initial admission and extensions at up to 240 days aligned with assignment length. The rule would require extensions to be approved by U.S. Citizenship and Immigration Services, enabling periodic DHS assessments. The proposal revives a 2020 initiative previously withdrawn and signals planned regulatory changes to the H-1B and lawful permanent residence processes.
