If the headlines about the September 15 form change made you feel like you're already behind — you're not. No F-1 student can file an extension of stay under the new rule yet, and the new form edition can't even be downloaded until September 15. But the date that decides whether you'll ever need to file is already printed on your I-20, and the next 30 days are the cheapest time to look at it.
On August 14, 2026, USCIS announced that new editions of Form I-539 (Application to Extend/Change Nonimmigrant Status) and Form I-765 (Application for Employment Authorization) will be published on September 15, 2026. Both will carry the edition date 09/15/26. Neither is available today. (USCIS alert)
The forms are being rewritten to implement the DHS final rule that ends "Duration of Status" — Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure, 91 FR 44976, published July 17, 2026, effective September 15, 2026, amending 8 CFR parts 214, 248, and 274a. (Federal Register)
This is a final rule, not a proposal — the comment period is closed and the text is locked. But it is not operative yet. As of August 2026, no court has stayed or vacated it and DHS has not delayed the effective date. Litigation is still possible between now and September 15, so confirm the rule's status on the day you file.
| Your filing date | Form I-539 edition to use | Form I-765 edition to use | Outcome if you get it wrong |
|---|---|---|---|
| On or before Sept 14, 2026 | 08/28/24 | 08/21/25 | Filing a 09/15/26 edition early = not accepted |
| On or after Sept 15, 2026 | 09/15/26 | 09/15/26 | Filing an older edition = rejected, fee returned, you refile |
That first row matters mostly for people filing an I-539 or I-765 for something other than an F-1 extension of stay right now — a change of status, an OPT or STEM OPT application, a dependent's filing. F-1 extension of stay is a September 15 concept only.
Two operational details that trip people up:
We covered the announcement itself here: USCIS Sets New I-539 and I-765 Form Deadline. This guide picks up where that news brief stops — with what an F-1 student actually has to do about it.
Watch this one: USCIS's August 14 alert named Forms I-539 and I-765. It did not separately address Form I-539A, the supplement your F-2 spouse or children file with you. Download I-539 and I-539A together from uscis.gov/i-539 on the morning you file, and confirm both edition dates at the bottom of each page.
For decades, your I-94 said "D/S." There was no end date. Your DSO extended your program in SEVIS, and USCIS was never involved.
That ends September 15, 2026. Under the final rule:
For the full picture on program changes, transfers, and the second-master's restriction, see our companion guide: The D/S Rule Is Final: What Every F-1 Student Needs to Know.
Today, you can't. The extension-of-stay procedure doesn't exist until September 15, 2026, and USCIS will not accept the 09/15/26 form edition before that date. Right now, F-1 program extensions are still handled by your DSO in SEVIS.
And September 15 isn't a filing date either — for most students it's just the day the clock changes. The transition provision protects students who are already here.
If you were admitted for D/S and are maintaining valid F-1 status on September 15, 2026, you may remain until the later of your I-20 program end date or your OPT/STEM OPT EAD end date — capped at four years from September 15, 2026, i.e. September 15, 2030 — and you keep the 60-day grace period.
You keep that 60-day grace period until one of two things happens:
There is also a carve-out worth real money if you're finishing soon: if you were admitted for D/S before September 15, 2026 and you timely file Form I-765 for post-completion OPT or a STEM OPT extension on or before March 18, 2027, you generally do not need a separate Form I-539 for that OPT period. You lose that carve-out if you depart and re-enter the U.S. before filing the I-765.
| File Form I-539 with USCIS | Depart and re-enter at a port of entry | Do nothing (rely on the transition rule) | |
|---|---|---|---|
| Who this fits | You need time past your I-20 end date | You already must travel, and your visa is valid | You're in status on 9/15/2026 and finishing on schedule |
| Cost | $470 paper / $420 online | Airfare + visa renewal if your F-1 visa has expired | $0 |
| Grace period after | Drops to 30 days | Drops to 30 days | Stays at 60 days |
| New admission length | Up to your new I-20 end date | New period of admission, up to 4 years | Unchanged: I-20 end date, max through 9/15/2030 |
| Can you stay in the U.S. while it processes? | Yes — timely filing keeps you here and studying | No — you're outside the U.S. | Not applicable |
| Premium processing available? | No — not for extension of stay in F-1 | Not applicable | Not applicable |
| Biggest risk | Denial means you must depart with no grace period | Visa refusal or 221(g) leaves you stranded abroad | You forget your I-20 date and file late |
| Effect on the March 18, 2027 OPT carve-out | Approval converts you to a date-certain I-94 | Destroys the carve-out if you leave before filing I-765 | Preserves it |
Filing fee (per USCIS fee schedule Form G-1055, edition 05/29/26 — last verified August 2026):
Filing online saves you $50. G-1055 does not list a separate biometric services fee line for Form I-539, though USCIS may still schedule you for a biometrics appointment.
Speed: this is the part that hurts. Premium processing on Form I-539 costs $2,075 for a 30-business-day decision as of March 1, 2026 — but USCIS offers it only to applicants changing status into F, M, or J. It is not available for an extension of stay in F-1 status. (USCIS premium processing expansion)
You cannot buy your way to a faster F-1 extension. The only lever you control is filing early.
Premium processing is available on Form I-765 for F-1 OPT and STEM OPT at $1,780 for 30 business days (effective March 1, 2026).
What USCIS wants to see. The final rule sets the standard: a currently issued Form I-20 showing that additional time is needed to complete your program, or documentation of compelling academic reasons, a documented illness or medical condition, or exceptional circumstances beyond your control. The rule states that delays caused by academic probation, suspension, or repeatedly failing to complete coursework are generally not acceptable reasons.
If you filed before your admission period expired — "timely filed" — yes, with limits.
| While a timely-filed I-539 is pending | Allowed? |
|---|---|
| Remain in the U.S. past your Admit Until Date | Yes |
| Continue a full course of study | Yes — the rule authorizes it until USCIS decides |
| On-campus employment | Yes — auto-extended up to 240 days |
| CPT (including Day 1 CPT) | Yes — auto-extended up to 240 days, or your DSO-authorized end date, whichever is earlier |
| Severe economic hardship employment | Yes — auto-extended up to 240 days |
| Start post-completion OPT | No — you cannot begin OPT until the I-765 is approved |
| STEM OPT extension | Keeps the existing 180-day automatic extension on timely filing |
| International travel | High risk — departure can be treated as abandoning the I-539 |
Two hard edges to know:
If you're relying on CPT income while a case is pending, read our breakdown of current CPT scrutiny: Day 1 CPT Paused? What SEVP's CPT Memo Actually Says.
All three are self-funded working professionals in a Day 1 CPT master's program. All three were admitted for D/S and are in valid status on September 15, 2026.
Student A — I-20 program end date June 30, 2027. Does not travel. Protected by the transition rule. Her authorized stay runs to June 30, 2027, plus a 60-day grace period = August 29, 2027. She files no I-539 and pays $0. If she graduates on time and files OPT, she's done.
Student B — same June 30, 2027 I-20. Flies home December 20, 2026, re-enters January 5, 2027. Re-entry converts her to a date-certain I-94 ending June 30, 2027, with only a 30-day grace period = July 30, 2027. She lost 30 days by taking one trip. If she also had planned to file OPT under the March 18, 2027 carve-out, leaving before filing the I-765 forfeits it.
Student C — I-20 program end date November 30, 2026. Needs one more semester, through April 30, 2027. He must file Form I-539 before November 30, 2026, using the 09/15/26 edition, paying $420 online. He needs a new I-20 from his DSO showing the April 30, 2027 end date plus a documented academic reason. No premium processing is available, so he asks his DSO for the updated I-20 in September 2026 and files in early October — roughly 8 weeks of buffer. While pending, he keeps studying and keeps his CPT income for up to 240 days.
The difference between Student A and Student C is not luck. It's a date on a PDF that most students never look at.
Not sure whether USCIS actually got your filing? Here's how to read your receipt: How Do I Know If USCIS Received My Application?
Filing is not free and it is not always the right move. An extension of stay is probably the wrong step right now if:
On Day 1 CPT specifically: the D/S final rule does not eliminate Day 1 CPT, and DHS said so directly in the rule. But 2026 is a high-scrutiny environment. Attendance records, alignment between your job duties and your program, and travel timing all matter more than they did two years ago. Choose your program on academic fit and employment outcomes, not on the CPT start date alone. Our Day 1 CPT guide covers what to check before you enroll.
Do I have to file Form I-539 on September 15, 2026? No — and before that date you couldn't even if you wanted to. September 15, 2026 is when the new form edition is published and the D/S rule takes effect; it is not a filing deadline. If you're in valid F-1 status that day and were admitted for D/S, the transition rule lets you stay through your I-20 program end date (capped at September 15, 2030) plus 60 days without filing anything.
How much does an F-1 extension of stay cost in 2026? $470 for paper filing and $420 for online filing, per USCIS fee schedule G-1055 (edition 05/29/26). G-1055 lists no separate biometric services fee for Form I-539. Last verified August 2026.
Can I use premium processing to speed up my I-539? No. Premium processing on Form I-539 ($2,075, 30 business days as of March 1, 2026) is available only for applicants changing status into F, M, or J — not for extending an existing F-1 stay. Your only real lever is filing early.
Can I keep working on CPT while my I-539 is pending? Yes, if you filed before your admission period expired. On-campus employment, CPT, and severe economic hardship employment are automatically extended for up to 240 days, or until your DSO-authorized end date, whichever comes first. You cannot start post-completion OPT until the I-765 is approved.
What happens if my I-539 is denied? There is no grace period following a denial — you are expected to depart the United States. Unlawful presence begins accruing after your admission period expires; 180 days triggers a 3-year re-entry bar and one year triggers a 10-year bar. This is the strongest argument for filing months, not weeks, ahead.
Does travelling outside the U.S. change my extension deadline? Yes. If you were admitted for D/S and you leave and re-enter after September 15, 2026, you're readmitted with a date-certain I-94 and a 30-day grace period instead of 60. If you were counting on the March 18, 2027 OPT carve-out, departing before you file Form I-765 forfeits it.
