U.S. Citizenship and Immigration Services is rolling out a wave of form changes in the third week of September that immigration applicants cannot afford to overlook.
USCIS will require new editions of Forms I-539 and I-765 beginning September 15, 2026, with no grace period for previous versions.
Just three days later,
on September 18, 2026, USCIS will publish a revised edition of Form I-485, Application to Register Permanent Residence or Adjust Status.
The result: three of the most frequently filed immigration forms in the country will undergo mandatory changes within a single week — and in each case, USCIS has confirmed there will be no transition period.
What's Changing and Why
USCIS has announced that it will publish revised editions of Form I-539, Application to Extend/Change Nonimmigrant Status, and Form I-765, Application for Employment Authorization, on September 15, 2026. The updated forms are being issued to implement DHS's recently finalized rule replacing "Duration of Status" (D/S) with fixed admission periods for certain F, J, and I nonimmigrants.
On July 17, 2026, DHS issued a final rule that eliminates the "duration of status" framework and imposes fixed admission periods of up to four years for F-1 and J-1 nonimmigrants and up to 240 days for I nonimmigrants.
The September 15 effective date for that rule is what's driving the urgency behind the form changes.
Specifically, USCIS announced that the 09/15/26 editions of both forms will replace the 08/28/24 edition of Form I-539 and the 08/21/25 edition of Form I-765.
Meanwhile,
the Form I-485 has been revised to align with the recently announced Public Charge Ground of Inadmissibility Final Rule.
No Grace Period — A Hard Cutoff
What makes this update especially consequential is the absence of any transition window.
USCIS frequently provides a transition period following a form revision during which both the old and new editions may be accepted. That will not happen with these two forms. USCIS specifically states that there will be no grace period because the revised forms are necessary to implement the new fixed-period-of-admission rule.
The same applies to the I-485.
USCIS is providing a preview version of the 09/18/26 edition of Form I-485 and its instructions because there is no grace period for accepting the revised edition of Form I-485.
Here is what applicants need to understand about the filing windows:
For Forms I-539 and I-765:
-
USCIS will only accept the 09/15/26 edition of Form I-539 if it is postmarked or electronically submitted on or after September 15, 2026. The 08/21/25 edition of Form I-765 will be rejected if it is postmarked or electronically submitted on or after September 15, 2026.
For Form I-485:
-
Before September 18, 2026, USCIS will only accept the current edition of Form I-485 (edition date: 01/20/25). On or after September 18, 2026, USCIS will only accept the new 09/18/26 edition. The old 01/20/25 edition will be rejected if it is postmarked or electronically submitted on or after September 18, 2026.
Critically, applicants also cannot jump ahead.
The new editions cannot be filed early. USCIS will reject a 09/15/26 edition postmarked or e-filed before September 15, 2026, even though preview versions are already posted.
Who Is Most Affected?
The I-539 and I-765 changes have the most direct impact on international students and exchange visitors.
F and J students and alumni use Form I-539 to extend or change their nonimmigrant status. They use Form I-765 to apply for employment authorization, including F-1 Optional Practical Training (OPT), STEM OPT extensions, and J-2 employment authorization.
The change is especially important for international students applying for Optional Practical Training (OPT) or STEM OPT, since those applications require Form I-765.
An F-1 student preparing an OPT or STEM OPT application around the September 15 transition should double-check the edition date immediately before filing. Using an outdated edition after the cutoff could lead to rejection, potentially creating complications when an applicant is already working within a limited OPT or STEM OPT filing window.
Under the new fixed-admission framework,
F, J, and I nonimmigrants who need to remain beyond their authorized admission period must file extension of stay applications with USCIS, submit biometrics, and demonstrate continued eligibility.
This means Form I-539 filings are expected to surge in the months ahead.
The I-485 changes, meanwhile, affect a broader population — anyone applying for a green card through adjustment of status.
Although most of the form remains unchanged, USCIS has significantly revised the public charge section and removed much of the detailed explanatory guidance that previously appeared in the Form I-485 instructions. Most of the updates are concentrated in Part 9, which covers public charge-related questions.
The Bigger Picture: End of Duration of Status
The form revisions are part of a fundamental shift in how the United States admits certain nonimmigrants.
A significant consequence of the shift to fixed admission periods is the increased potential to accrue unlawful presence. Under the D/S framework, unlawful presence generally did not accrue absent a formal determination by USCIS or an immigration judge that an F, J, or I visa nonimmigrant was no longer maintaining status.
Under the new system, maintaining lawful status may require more attention to the expiration date on Form I-94 and, when necessary, timely applications to extend a person's stay. For certain F and J nonimmigrants, this means Form I-539 may play a more significant role in maintaining status when additional time in the United States is required.
Employers, universities, exchange visitor sponsors, teaching hospitals and media organizations should evaluate whether additional tracking systems, extension-of-stay support and I-9 reverification procedures are needed to address the transition from D/S admissions to fixed admission periods.
Practical Steps for Applicants
With three major forms changing within days of each other, careful planning is essential. Here is what applicants and practitioners should do:
1. Verify the edition date before filing.
Every USCIS form shows its edition date at the bottom of each page, and each form's webpage lists the edition currently accepted. An edition mismatch is a common reason USCIS rejects otherwise complete applications.
2. Review the preview versions now.
USCIS has released preview versions of the 09/15/26 editions of both forms, along with their instructions, in advance of the effective date.
Familiarizing yourself with the changes before September 15 can prevent last-minute errors.
3. Time your submission carefully.
The postmark date controls paper filings, and the submission date controls online filings.
Filing in the days surrounding September 15 or September 18 requires extra vigilance.
4. Understand rejection vs. denial.
If USCIS rejects a form because you used the wrong edition, that is different from denying your immigration benefit. A rejection means USCIS did not accept the filing because of the form problem.
You can refile with the correct edition, but you will lose time — and in some cases, that delay can have serious status consequences.
5. Consult an immigration attorney. The convergence of three form changes with two major final rules — the end of Duration of Status and the new Public Charge rule — makes professional guidance particularly valuable for filings in mid-to-late September.
Looking Ahead
The final rule is classified as a major rule and remains subject to congressional review.
The effective date is September 15, 2026. However, at the conclusion of the congressional review, if the effective date has been changed, DHS will publish a document in the Federal Register to establish the actual effective date or to terminate the rule.
For now, applicants should plan as though September 15 and September 18 are firm deadlines. The stakes of filing the wrong form edition — potential rejection, lost filing fees, and gaps in status or work authorization — are simply too high to leave to chance.
