Cap-Gap Extension: How It Works Now That It Runs to April 1, What Ends It, and What to Do If Your H-1B Is Still Pending

Quick answer: A cap-gap extension automatically keeps an F-1 student in status, and keeps OPT work authorization alive, after the OPT card expires while a cap-subject H-1B change-of-status petition is pending or approved. Since a DHS rule took effect on January 17, 2025, it lasts until April 1 of the H-1B fiscal year (not October 1 as before), or until the approved H-1B start date if that comes first (Study in the States, April 28, 2025). For FY 2027 petitions, that means work authorization through March 31, 2027. It ends early if the petition is denied, withdrawn, rejected or revoked, or if you leave the US while the change of status is pending.

This guide is for F-1 graduates whose employer filed an H-1B petition this year, people whose petition is still pending after October 1, and anyone on OPT trying to work out whether cap-gap can protect them. If you are still counting days without a job, read our guide to OPT unemployment days first, because cap-gap does not reset that clock. This is general information, not legal advice. Your DSO and your employer's immigration attorney have the final word on your case.

What is a cap-gap extension?

"Cap-gap" is the stretch of time between the end of your F-1 status or OPT and the start of your H-1B status. It exists because of the calendar. Employers can't file a cap-subject H-1B petition more than six months before the start date, so the earliest filing date is April 1 and the earliest start date is October 1, the first day of the federal fiscal year (USCIS). Most May graduates see their 12-month OPT end in late spring or summer, months before an October H-1B start.

The cap-gap rule fills that hole. It is automatic: you don't file anything and you don't get a new EAD card. USCIS says the only proof currently available is an updated Form I-20 from your DSO showing the extension, and that the updated I-20 is proof, not a requirement, for you to keep working (USCIS).

There are two kinds of cap-gap extension, and the difference matters:

Your situation when USCIS received the petition	What cap-gap gives you	Source
On valid post-completion OPT or STEM OPT	F-1 status and permission to keep working	USCIS M-274, 7.4.2
In the 60-day grace period after OPT ended	F-1 status only. No work until H-1B status starts	USCIS
Still in your degree program	F-1 status. Work only under your existing on-campus or CPT rules	USCIS M-274, 7.4.2

The new rule: cap-gap now runs to April 1, not October 1

Until January 2025, cap-gap ended on October 1. If USCIS hadn't approved your petition by then, your OPT-based work authorization stopped even though the petition was still pending. The modernization rule published in December 2024 (Federal Register) moved the end date to April 1 of the fiscal year. Study in the States says it applies to students with timely filed cap petitions starting with the FY 2026 registration period (Study in the States).

What this means today:

• FY 2027 petitions (filed from April 1, 2026 with an October 1, 2026 or later start): cap-gap can last until April 1, 2027. On Form I-9, employers enter "CAP-GAP" and March 31 of the fiscal year as the expiration date, then reverify by March 31 (USCIS M-274).
• If USCIS approves your petition, H-1B status begins on the validity start date of the approval, and cap-gap ends then, whichever comes first (USCIS).
• Watch out for old pages. Some university and blog pages still say cap-gap ends September 30 or October 1. Check the "last updated" date on anything you read. The USCIS cap-gap page was last reviewed January 17, 2025, and reflects the April 1 rule.

Who qualifies for a cap-gap extension?

You qualify if all of these are true (Study in the States; USCIS):

1. Your registration was selected in the H-1B lottery, and your employer then filed the full petition. A registration alone does not start cap-gap.
2. The employer is cap-subject. Cap-exempt employers, such as universities and nonprofit research organizations, can file at any time, so their petitions don't get cap-gap.
3. The petition asks for a change of status inside the US, not consular processing.
4. It was filed during the filing period while you were still in F-1 status (in school, on OPT, or in the 60-day grace period).
5. It requests a start date in the fiscal year being applied for.
6. You haven't violated your F-1 status.

Situations where cap-gap does not apply

Situation	Why it fails	What to do
Registered but not selected	No petition was filed	Plan around your OPT or STEM OPT dates and next year's registration
Employer chose consular processing	Cap-gap covers only change-of-status requests	Expect to leave and get an H-1B visa abroad before starting
Cap-exempt employer	Those employers can file year-round	Time the petition so your OPT doesn't run out first. See cap-exempt H-1B employers
Petition received after your grace period ended	You were no longer in F-1 status	Talk to an immigration attorney right away
Petition received after the EAD expired, during grace	You get status only, not work	Don't work until H-1B status starts

The FY 2027 picture

The odds of being in cap-gap at all shrank this year. USCIS used a weighted lottery for the first time for FY 2027. Registrations at wage level IV were entered four times and level I once (USCIS H-1B Cap Season). About 211,600 registrations were properly submitted, down roughly 38% from 343,981 the year before. USCIS said on July 17, 2026 that it had enough petitions to fill the 85,000 cap, so there was no second lottery (Ellis, July 17, 2026).

So if you weren't selected in March 2026, cap-gap is not an option for this fiscal year. If you were selected and your petition is still pending today, the April 1, 2027 end date is your real deadline.

What about the $100,000 H-1B payment?

USCIS says the September 2025 proclamation doesn't apply to a petition requesting a change of status for someone inside the US when that change of status is granted. It does apply if USCIS finds the person ineligible for the change of status, for example because they departed the US before it was decided. On June 8, 2026, a federal court in Massachusetts vacated the agency guidance that implemented the payment. The First Circuit denied the government's request for a stay on July 24, and DHS says it is complying while it considers next steps (USCIS H-1B Specialty Occupations). For cap-gap students, the practical lesson is the same either way: don't travel while your change of status is pending.

What ends a cap-gap extension early

Event	What happens	Source
Petition denied, rejected, revoked or withdrawn	Cap-gap ends. You get a 60-day grace period from the notice to leave or change status	USCIS
Denial for status violation, fraud or misrepresentation	No grace period. You must leave immediately	USCIS (same page)
Approved for consular processing instead of change of status	Cap-gap ends even though the petition is approved	USCIS (same page)
You travel abroad while the change of status is pending	The change of status request is treated as abandoned	USCIS (same page)
Your OPT unemployment days run out	OPT can be terminated. The 90 or 150-day limit still applies during cap-gap	University of Utah ISSS
April 1 arrives with the petition still pending	Cap-gap ends. Talk to counsel about your status and work options	University at Buffalo ISS

Can I travel during cap-gap?

Only after approval. USCIS says you can generally travel and come back in F-1 status if the H-1B petition and change of status are approved, you return before the H-1B start date, and you are otherwise admissible. Leaving while the change of status is pending abandons it (USCIS). A CBP officer still makes the final call at the border. For most people whose FY 2027 petition is pending now, that means no December trip home unless counsel clears it in writing.

If your H-1B is still pending after October 1

This is the biggest group searching "cap gap extension" right now. Here is a checklist:

1. Get the updated I-20. Send your DSO the I-797C receipt notice. Some schools ask you to wait about two weeks after the receipt so SEVIS can update first (Northeastern OGS).
2. Make sure HR has the I-9 right. The M-274 tells employers to record your expired EAD plus the I-797C as a valid List A document, write "CAP-GAP" and March 31, 2027, and reverify by that date (USCIS M-274). If payroll flags you on October 1 while your petition is pending, show HR that section.
3. Ask about premium processing. USCIS says premium processing is available for all H-1B petitions (USCIS), with action promised within 15 business days for Form I-129 (USCIS premium processing). Your employer decides whether to pay for it.
4. Answer any RFE fast. A request for evidence pauses the decision, not your cap-gap, but the April 1 date doesn't move. Send your attorney transcripts, degree and past I-20s the same day they ask.
5. Stay in the country. See the travel rules above.
6. Keep working for the petitioning employer. Cap-gap hangs on that petition. If the job ends, the petition is usually withdrawn, and withdrawal ends cap-gap.
7. Track the date. Put March 31, 2027 on your calendar with reminders at 60 and 30 days, and check in with counsel if nothing has happened by February.

Laid off during cap-gap: what happens next

Layoffs are lower than last year but haven't stopped. Employers announced 573,195 job cuts through September 2026, down nearly 40% from the same period in 2025 (CBS News, Oct 1, 2026). Weekly jobless claims fell to 194,000 in late October (AP, Oct 29, 2026). Hiring is slow too. Payrolls grew by just 29,000 in September and unemployment was 4.2% (BLS, Oct 2, 2026).

If you're laid off during cap-gap, your outcome depends on one question: is your OPT or STEM OPT card still valid?

Your OPT card	What USCIS says	Your next move
Still valid (for example, STEM OPT running into 2027)	You can keep using your remaining OPT with a new employer if the H-1B petition is withdrawn before the change of status takes effect and your DSO requests a SEVIS data fix	Find an OPT-appropriate job, report it, and watch your unemployment days
Expired, you were relying on cap-gap	Withdrawal ends cap-gap, and work authorization ends with it. USCIS gives a 60-day grace period from the notice to depart	Talk to counsel the same week about any way to stay, and start applying immediately
Petition already approved and H-1B status started	You are in H-1B status. The 60-day H-1B grace period and portability rules apply	See our H-1B 60-day grace period and H-1B transfer process guides

Sources: USCIS, Changes in Employment. If the withdrawal doesn't reach USCIS before the change-of-status date, USCIS says you would need to stop working and file Form I-539 to return to F-1 before resuming OPT.

Can I apply for STEM OPT during cap-gap?

Yes, if you are eligible and the cap-gap is still active. USCIS says you can't apply once cap-gap has ended because the petition was rejected, denied, revoked or withdrawn and you are in the grace period (USCIS). If your petition looks shaky and you have a STEM degree, raise this with your DSO early.

Cap-gap timeline with real dates

Here is a typical FY 2027 case, using the dates USCIS published for this season:

Date	What happened	Cap-gap effect
March 4 to 19, 2026	Employer registers you	None yet
March 31, 2026	USCIS completes selection (USCIS)	None yet
April 20, 2026	Petition received with change of status and October 1 start, while your EAD is valid	Cap-gap is now locked in for status and work
June 15, 2026	OPT card expires	You keep working on cap-gap. HR updates the I-9
October 1, 2026	Fiscal year starts. Petition still pending	Under the old rule, work would stop here. Now it continues
March 31, 2027	Last day of cap-gap work authorization	Reverification due. If still pending, call counsel before this date

If the petition is approved on, say, November 12, 2026, your H-1B status begins on the validity start date shown on the approval notice, and cap-gap ends that day.

Mistakes that cost people their cap-gap

• Assuming selection equals protection. Only a filed petition starts cap-gap.
• Letting the EAD expire before the employer files. Filing during grace gets you status, not work.
• Traveling while pending. This is the most common, most costly mistake.
• Not asking which filing route was used. Ask your employer in writing whether the petition requested a change of status or consular processing.
• Treating cap-gap as a fresh clock. OPT unemployment limits still apply.
• Waiting for HR to fix an I-9 problem. Send them the M-274 cap-gap section the day payroll looks wrong.

DIY, job tools, or a human application service?

Most people in cap-gap are employed. The job search matters when a petition is denied, an employer withdraws it, or you weren't selected and are working on STEM OPT while you plan for the next lottery. Here is how the options compare:

Approach	Good for	Watch out for
Doing it yourself	Full control, no cost	Tailoring and checking sponsors take hours a week while a grace period or OPT count runs
Resume and tracking tools such as Teal and Careerflow	Tailoring resumes and tracking applications	You still find the jobs and submit each one
Autofill and discovery tools such as Simplify and Jobright	Filling forms faster and finding more postings	Check every sponsorship and work-authorization answer yourself
Auto-apply tools such as LazyApply and JobCopilot	Speed on short, repetitive forms	Confirm how the tool answers "will you require sponsorship" before it runs
Human application services such as scale.jobs or ResumeToJobs	A person submits tailored applications while you handle counsel, your DSO and interviews	Give the service your exact visa answers in writing

Scale.jobs covers cap-gap as one step in its broader OPT-to-H-1B timeline (scale.jobs, Aug 14, 2026). This page goes deeper on the part that matters after October 1: the April 1 end date, the I-9 entries, what ends cap-gap early, and what to do if you are laid off mid-gap.

ResumeToJobs is the human-assisted option here. We take your visa and sponsorship answers once, focus on employers with an H-1B filing record or cap-exempt status, tailor your resume to each posting, and submit for you. Credits cost $0.50 each, and one credit is one tailored application submitted for you. Five hundred credits cost $225, which is 10% off, with no subscription. We don't give immigration advice, so keep your DSO and attorney involved in anything status-related.

Other rules in flux

Two other changes come up in cap-gap questions. The DHS rule that would replace "duration of status" with fixed admission periods was postponed by a federal court on September 14, 2026, and current F-1 rules remain in place while the case continues (Northeastern OGS, updated Sept 15, 2026). DHS also proposed new OPT-related school fees in October, which are not in effect; see proposed OPT fees. Neither changes the cap-gap rules today.

The bottom line

A cap-gap extension is automatic, but it is fragile. It needs a selected registration, a timely filed cap-subject petition asking for a change of status, and an employer who keeps that petition alive. For FY 2027 petitions it can carry your F-1 status and OPT work authorization to April 1, 2027. Get the updated I-20, make sure HR records the I-9 correctly, stay in the US while the petition is pending, and watch your unemployment days. If the job or the petition goes away, the clock changes fast, so speak with your DSO and an attorney that week and restart your search right away.
