F1 Student Visa Rules and Regulations: How to Stay Compliant and Avoid Violations (2026)

Getting your F-1 visa is the start, not the finish. From the moment you are admitted, your legal right to stay depends on continuously following the rules, and most students who run into trouble do so by accident, through a quiet violation that surfaces later during travel, work authorisation or a future application. The rules changed meaningfully in 2026, so even students already in the U.S. need to re-read the basics.

Major 2026 change you must know about

On July 17, 2026, DHS published a final rule (effective Sept 15, 2026) that ends the long-standing “Duration of Status” admission for F students and replaces it with a fixed period of admission. If it stands, you will be admitted for a set period (up to the length of your program, generally not beyond four years) and must file an Extension of Stay to continue longer. The rule is subject to congressional review, so confirm the current position on the official DHS Study in the States final-rule page before relying on any date.

Quick Summary - Before you proceed

• Stay enrolled full-time at the school on your I-20; drop below full course of study only with your DSO’s prior approval.
• Work only when authorised. On-campus work is capped at 20 hours/week in session; off-campus work needs specific authorisation. Unauthorised work is the fastest way to lose status.
• Keep documents valid (passport 6+ months ahead, current I-20) and tell your DSO about any change of address, program or level.
• Fixed admission period (2026 rule): D/S is being replaced; longer stays need an Extension of Stay via Form I-539.
• Grace period is changing: historically 60 days after your program to depart or change status; the 2026 rule reduces this to 30 days. Confirm which applies to you.

What are the rules for maintaining F-1 status?

Per DHS’s Maintaining Status guidance, these are the non-negotiables:

• Full course of study: Undergraduates generally need at least 12 credit hours per term; graduate students take a full load as certified by the school. Contact your DSO before dropping below full-time; a reduced course load is allowed only in limited, pre-approved situations.
• Report to your DSO: Contact them on arrival (by your I-20 program start date) and whenever your address, name, program or funding changes. DSOs must report many changes within set timeframes.
• Keep documents valid: Passport valid at least six months into the future, and a current, correctly signed I-20.
• Do not overstay: Leave or change status within your grace period after completing your program or practical training.

Can you work on an F1 student visa?

More students lose status over work than almost anything else, because the rules are narrow and strictly enforced. Any work should be treated as a legal compliance question, not an informal arrangement.

The golden rule from DHS: never work without authorisation. Doing so can force you to leave the U.S. immediately and can bar re-entry. 

What the 2026 fixed-admission rule changes?

Under the old system, your I-94 said “D/S,” meaning you could stay as long as you maintained status, with no fixed end date. The DHS final rule changes this. Key points as published:

• Fixed admission period up to the length of your program on the I-20, generally not exceeding four years, plus short arrival/departure windows.
• Extension of Stay via Form I-539 with USCIS if you need more time (program extension, a higher-level program, OPT/STEM OPT, transfers).
• Shorter grace period: the post-program departure window is reduced from 60 days to 30 days.
• Limits on changing programs, including a bar on starting another program at the same or a lower level after completing a degree.
• Transition period for students already admitted under D/S when the rule takes effect.

Because the rule is subject to congressional review and further agency guidance, dates and details may shift.

The 2025 enforcement context (why compliance matters more now)

Compliance stopped being a formality in 2025. The government revoked a large number of student visas and terminated many students’ SEVIS records, in some cases citing social media activity or database records. Two practical takeaways:

• Check your SEVIS status periodically through your DSO; do not assume “no news is good news.”
• A visa revocation and a SEVIS termination are different things, and either is serious. If either happens, contact your DSO and an immigration attorney immediately.

For students admitted under D/S, unlawful presence generally does not begin automatically on a SEVIS termination; it typically starts only after a formal finding of a violation. That nuance can matter a great deal, so get advice quickly rather than self-diagnosing.

Wrapping up

Staying compliant on an F-1 visa comes down to a short list: enrol full-time, work only when authorised, keep your documents and DSO updated, and leave or extend on time. With the 2026 shift away from Duration of Status, the timing rules matter more than ever, so build a habit of checking your status and talking to your DSO before you make any change.

FAQs

How many hours can I work on-campus?

Up to 20 hours per week while school is in session, and more during official breaks, if you are in valid status.

What happens if I work without authorisation?

It is a serious violation. DHS says you may be forced to leave immediately and could be barred from re-entering.

Is Duration of Status going away?

Under the 2026 DHS final rule, yes, it is replaced by a fixed admission period with an Extension of Stay process, effective Sept 15, 2026 (subject to review).

How long is the grace period after my program?

Historically 60 days; the 2026 rule reduces it to 30 days. Confirm which applies to your situation.

Who is responsible for my compliance?

You are. Your school reports in SEVIS, but responsibility for maintaining status rests with the student.
