D/S vs. Fixed Duration
Historically, F-1 student visas were marked "D/S" on the Form I-94 arrival record, meaning students remained in legal status as long as they maintained SEVIS compliance and were enrolled full-time. The new policy limits this by requiring extensions for any stay exceeding the fixed period granted at entry.
How It Affects You
Existing Students (Transition Guidelines):
D/S Grandfathering: You will remain under the "Duration of Status" guidelines for a transition period. However, any change in educational level (e.g., Bachelor's to Master's) or transfer on or after September 15, 2026 will trigger the fixed period admission requirement.
Action Required: Monitor your I-20 program end date. If you need a program extension, consult your DSO early as extensions will now require additional USCIS processing times.
How to Maintain Status under Fixed Admission
- Keep SEVIS Active: Always remain registered full-time.
- Apply for Extensions Early: File Form I-539 at least 90–120 days before your fixed period expiration to avoid lapses.
- Coordinate with DSO: Work closely with your Designated School Official (DSO) for any changes in your program of study.
