Overview
- DHS published the final rule in mid‑July and it takes effect on September 15, 2026, replacing the decades‑old D/S system with fixed I‑94 admission dates for F, J and I nonimmigrants.
- Transition provisions let many current students remain until their program end date or a transition cutoff, but leaving and reentering after the effective date will often trigger the new fixed‑period I‑94 rules.
- The rule generally caps many student and exchange admissions at four years and requires USCIS extension‑of‑stay filings with biometrics, background checks and fees for anyone who needs more time.
- Universities, research labs and higher‑education groups say the limits and added federal adjudication could delay PhD and medical training completion, reduce international graduate enrollment and strain advising resources and budgets.
- Stakeholders are preparing for likely USCIS processing bottlenecks, urgent travel and reentry advisories, and legal and congressional scrutiny as institutions plan extension workflows before full implementation.
