If you are planning to study in the United States, mark September 15, 2026 on your calendar. On that date, the US Department of Homeland Security ends the decades-old "Duration of Status" system that F-1 students have relied on for as long as most applicants have been alive. According to the American Immigration Council, this is one of the biggest changes to US student visa policy in a generation, and it lands at the same time Nepal is already seeing record F-1 refusal rates.
What Is Actually Changing on September 15, 2026
Until now, F-1 students were admitted for "Duration of Status" (D/S), meaning you could stay in the US for as long as you remained a full-time student in good academic standing, with no fixed exit date stamped in your passport. That system ends on September 15, 2026. According to a detailed breakdown from immigration law firm Grape Law Firm, here is what replaces it:
- Fixed admission period. You will be admitted only until the end date of your specific academic program, or four years, whichever is shorter.
- Extension of Stay (EOS) required. If your program runs longer than four years, or you need more time to finish, you must file a formal Extension of Stay application with USCIS before your authorized period ends.
- Shorter grace period. The grace period after finishing your program is being cut from 60 days to 30 days, giving you less time to leave the US, transfer to a new program, or change status.
- Applies to current students too. This is not just for new applicants. If you are already in the US on an F-1 visa, the fixed admission period and shorter grace period apply to you as well once the rule takes effect.
Old System vs New System, Side by Side
- Admission length: Old, open-ended for as long as enrolled (D/S). New, fixed to program end date or 4 years, whichever is shorter.
- Need more time: Old, simply stayed enrolled. New, must file Extension of Stay with USCIS before the authorized period ends.
- Grace period after finishing: Old, 60 days. New, 30 days.
- Who it applies to: Old rules covered everyone before Sept 15, 2026. New rules cover new arrivals and existing F-1 students alike from that date forward.
In practice, this means every F-1 student now needs to track a hard end date the same way H-1B or other nonimmigrant visa holders do, instead of simply staying enrolled and assuming status continues automatically.
Why This Matters More for Nepali Students Right Now
This policy shift lands at an already difficult moment for Nepali applicants. According to US Department of State visa data reported by Nepal News, Nepal's F-1 refusal rate jumped to 81 percent in fiscal year 2025, up sharply from 59 percent in fiscal year 2024. The effect shows up clearly in enrollment numbers: out of nearly 66,000 Nepalis who went abroad for education by mid-July 2026, only 1,673 chose the United States, a dramatic shift away from what was once one of the top three destinations for Nepali students.
Consular officers are also reported to be asking more detailed questions about bank account history, recent large deposits, and the source of sponsorship funds, since verifying that money is genuinely available (not borrowed just before the interview) has become a bigger part of the screening process. A separate DHS notice outlines additional, stricter regulations expected to take effect around the same September 2026 window, aimed at reducing visa misuse and tightening oversight of schools that enroll F-1 students.
Step by Step: Preparing Your Application Under the New Rules
- Pick a program length you can finish inside four years. If your intended degree, including any foundation or bridge year, runs longer than four years, plan from day one for an Extension of Stay conversation with your school.
- Start your bank statement history at least 6 to 12 months before applying. Officers are trained to flag sudden, unexplained large deposits made right before an interview. A steady, well-documented balance is far stronger evidence than a lump sum that appeared last month.
- Prepare a clear funding explanation, not just a bank letter. Be ready to explain, in your own words, exactly how tuition and living costs will be covered for the full length of your program: family income, savings, a sponsor's income, or a combination.
- Confirm your I-20 program end date with your school's international student office before you travel, and understand how the new fixed admission period will apply to you specifically.
- Know your grace period math. With only 30 days after your program ends, decide in advance whether you are applying for OPT, transferring schools, or returning home, rather than figuring it out after graduation.
What Current F-1 Students Should Do Right Now
- Check with your Designated School Official (DSO) whether your program's expected completion date falls before or after September 15, 2026, and how that affects your specific status.
- If you are in a program likely to run past four years, such as many PhD tracks, start the Extension of Stay conversation with your DSO well in advance. USCIS processing takes time, and missing the window can put you out of status.
- Plan any post-graduation move, whether that is OPT, a transfer, or returning home, around the shorter 30-day grace period instead of the old 60-day cushion.
Common Mistakes That Trigger F-1 Refusals
With Nepal's refusal rate at 81 percent, small, avoidable mistakes are costing far more applicants their visa than in previous years. Based on the patterns behind the current tightening, these are the issues that come up most:
- Large, unexplained deposits close to the interview date. A bank balance that jumped significantly in the weeks before your appointment is one of the fastest ways to trigger follow-up questions you may not be able to answer convincingly.
- Vague answers about post-graduation plans. Officers are specifically screening for intent to return to Nepal. A rehearsed but generic answer reads as weaker than a specific, personal explanation tied to your family, career field, or business plans at home.
- Mismatched documents. If your I-20 financial sponsor, your bank statements, and your verbal explanation at the interview don't line up cleanly, it raises doubt even when the underlying situation is genuine.
- Choosing a program length without checking the four-year rule. Applying for a program that will clearly require an Extension of Stay, without being able to explain that plan, signals disorganization at exactly the moment you need to look prepared.
- Applying to a school with a poor track record on F-1 compliance. Part of the September 2026 DHS tightening specifically targets schools flagged for visa misuse; your own application can be affected by your chosen institution's history, so research the school's SEVP standing before committing.
How This Compares to Other Nonimmigrant Visa Categories
The shift to a fixed admission period is not unique to F-1 students. H-1B work visa holders, for example, have always had a fixed authorized stay tied to their petition, with extensions filed proactively rather than assumed. What changes for F-1 students is the mindset required: you can no longer treat your visa status as automatically renewing itself simply by staying enrolled. Building the habit of checking your I-20 end date the same way H-1B holders track their I-797 approval notice is the single most useful adjustment current and future F-1 students can make under the new system.
Frequently Asked Questions
Does this affect students who are already enrolled in the US?
Yes. The fixed admission period and the shortened 30-day grace period apply to current F-1 students once the rule takes effect on September 15, 2026, not only to new applicants.
What happens if I stay past the new grace period?
Staying beyond your authorized period without an approved Extension of Stay or a change of status can put you out of status, which affects future US visa applications, including tourist and work visas. Track your dates closely with your school's international office.
Is Optional Practical Training (OPT) affected by this change?
The core change here is about the admission period and grace period, not OPT eligibility itself. However, since your authorized stay is now tied to a fixed end date, you will need to plan your OPT application timeline around that date rather than an open-ended D/S period.
Why is Nepal's refusal rate so much higher than before?
The exact reasoning behind individual visa decisions is not published, but the pattern lines up with broader US policy tightening under the current administration, including closer scrutiny of financial documentation and intent to return home after study, both of which are core parts of the F-1 visa interview.
Should I still apply to US universities given these changes?
The US remains a strong academic option, but 2026 applicants need a noticeably stronger, more carefully documented file than in previous years. If your finances and program length are solid and well-documented, the new rules are manageable; they mainly punish vague or last-minute preparation.
Given Nepal's rising refusal rate, the strongest thing you can do right now is prepare a clean, well-documented application and get professional guidance on your specific program length before you apply.
