H-1B Cap Lottery from OPT: Cap-Gap & If You Lose

Who this is for: F-1 students on OPT or STEM OPT whose employer will try the H-1B cap lottery.

This is a planning guide, not legal advice. USCIS announces lottery dates, fees, and filing windows every year. Confirm on USCIS and with the employer’s attorney before anyone clicks “submit.”

Previous: STEM OPT extension: I-983 and reporting · OPT to H-1B timeline 2026–2027

Rule watch (F-1 duration of status): DHS published a final rule on July 17, 2026, effective September 15, 2026, that would shorten the post-completion grace period from 60 to 30 days for students admitted after the effective date, shorten the post-program-end OPT filing window from 60 to 30 days, and require Form I-539 for some extensions. A federal court postponed the rule on September 14, 2026, so the current rules described here still apply. Re-check with your DSO before you file.

Why the lottery is not the hard part

The lottery is not the hard part. The hard part is:

• Being employed and in status on the day USCIS opens registration
• Filing the petition on time if you are selected
• Using cap-gap correctly if your EAD dies in the summer
• Having a real plan the same week if you are not selected

Most F-1 horror stories are not “lost the lottery.” They are “won, then OPT expired before the petition was filed,” or “lost, then worked in the grace period.”

Quick answer: H-1B lottery and cap-gap

Next expected cycle for most 2026 graduates: March 2027 registration → FY2028 H-1B → start October 1, 2027. FY2027 (start Oct 1, 2026) registration already ran in March 2026.

How the cap lottery works (F-1 edition)

Cap-subject vs cap-exempt

Cap-subject (this article): most private companies. Limited visas per fiscal year. Lottery if registrations exceed the cap. New employment start is October 1.

Cap-exempt: certain universities, nonprofit research organizations, and related nonprofit entities. No March lottery. Can file year-round. If you can get a genuine cap-exempt job, it is often a better backup than “wait and hope.”

Do not assume a company is cap-exempt because it “works with a university.”

Wage-level weighting (new since FY2027)

DHS's weighted selection rule took effect February 27, 2026. Registrations now report the SOC code, the area of employment and the highest OEWS wage level the offered salary meets. Registrations are entered once (Level I), twice (II), three times (III) or four times (IV). The petition must later show those entries were accurate. A Level I entry-level offer therefore has the lowest odds, not only the most RFE risk. Check each season's USCIS notice, because litigation or later rulemaking could change this.

Beneficiary-centric selection

USCIS selects people, not registrations.

• Two employers registering you does not give you two tickets.
• Fake extra registrations (staffing mills, related companies with no real job) can destroy the case and worse.
• You still need one real job with one employer who will file I-129 if selected.

What “selected” means

Selected = the employer may file I-129 in the announced period.

Selected is not:

• An approved H-1B
• Permission to start in April
• A substitute for OPT
• Cap-gap by itself (the petition must be filed)

If the employer never files, selection expires and you have nothing.

Fees and who pays

Registration fees, I-129 fees, asylum/fraud fees, and (if used) premium processing are employer-side in a proper H-1B. If someone asks you to wire “lottery fees” to a personal account, walk away.

Amounts change. Use the current USCIS fee schedule. This article will not quote a number that will be wrong in three months.

Dates you should track (and which ones are not public yet)

USCIS posts the exact registration dates each winter. Until then, plan with seasons, not invented days.

For a May 2026 grad on OPT:

• March 2027 = first (and if non-STEM, often only) lottery
• October 1, 2027 = H-1B start if that lottery works
• March 2028 / 2029 = extra shots only if STEM OPT is approved and still running

What must be true before March

The lottery does not fix a weak job.

Specialty occupation

The role generally must require a bachelor’s degree in a specific field as a normal minimum. Title inflation (“engineer,” “analyst,” “consultant”) without duties and a degree match is a classic RFE.

Your OPT job and the H-1B job should be the same story. An I-983 that says “training in lab techniques” and an LCA that says “software developer” is a problem.

A real job with a real petitioner

The petitioner must have a bona fide job offer for you and actually direct and pay for the work. (Since January 17, 2025 the H-1B rule uses that test instead of the old “employer-employee relationship” wording; for third-party placements USCIS asks for contracts or end-client letters.)

High risk:

• You sit at a client site and the petitioner cannot say what you do tomorrow
• You are “employed” by a firm that only markets you
• You are really self-employed

This is both a STEM OPT issue and an H-1B issue. See article 2.

LCA (prevailing wage)

Before I-129, the employer files a Labor Condition Application with DOL:

• Job title and SOC code
• Work location(s) — remote work is a location
• Wage level (Level 1 wages draw RFEs)
• Hours

If HR does not know your worksite zip code in February, they are not ready for March.

Your status

You should be:

• In valid F-1 / OPT / STEM OPT
• Under unemployment-day limits
• Not working unauthorized

A selected lottery with a broken F-1 history becomes an RFE on maintenance of status.

Documents to give the attorney in February

• Passport, I-94, all I-20s
• OPT / STEM EADs
• Degrees + transcripts (+ evaluation if foreign degree)
• I-983 if on STEM
• Resume matching the petition job
• Pay stubs
• Exact addresses you will work

Registration week (March)

You usually cannot submit the registration. The employer or attorney does.

Your job:

1. Confirm legal name, date of birth, passport number, country of birth/citizenship match the passport
2. Get written confirmation that registration was submitted (not “we will”)
3. Save the confirmation number / screenshot
4. Do not start working differently because someone “entered you in the lottery”

If two employers both want to register you: that is allowed in principle, but it does not help odds. Only do it if both jobs are real and you know which one you will join if both would file. Chaos here looks like fraud later.

If you are selected

Immediate sequence

1. LCA certified (DOL). Not instant; do not wait until week 6 of the filing window.
2. I-129 prepared: specialty occupation letter, degree match, status history, org chart if needed.
3. Change of status vs consular notification — decide now:
   • Change of status (COS): you stay in the U.S., typically become H-1B on Oct 1 if approved. This is what cap-gap is built around.
   • Consular notification: you would get a visa stamp abroad. The $100,000 payment can apply to these petitions (change of status vs consular processing). Leaving while COS is pending can abandon COS. Do not mix these casually.
4. File I-129 inside the USCIS window and while OPT is valid if you need cap-gap.
5. Send the I-797C receipt to your DSO.

Premium processing

Pays for a faster I-129 decision. It does not:

• Move October 1 earlier
• Create cap-gap by itself
• Cure a bad specialty-occupation case

It can help travel planning after approval and reduce summer uncertainty.

RFEs F-1 students actually get

• Job is not a specialty occupation
• Degree field ≠ job
• Third-party / client-site control
• Unemployment days / unauthorized work / bad CPT
• Inconsistent I-983 vs LCA
• Employer cannot pay the wage (small / new company)

Answer with evidence. OPT continues to run during an RFE.

Cap-gap (read this twice)

Cap-gap is the automatic extension of F-1 status and post-completion OPT employment authorization through April 1 of the fiscal year (or your H-1B start date, if that is earlier), so you can keep working until the H-1B starts (October 1 for a normal cap-subject case).

It is not a form you file. It is not a new EAD card (you typically keep working on the combination of old EAD + I-129 receipt + cap-gap rules). HR I-9 teams get this wrong constantly. Have the USCIS cap-gap page ready.

Rule update: The H-1B modernization rule (effective January 17, 2025) moved the cap-gap end date from September 30 to April 1. If the H-1B petition is approved with an October 1 start, you switch to H-1B then and cap-gap simply ends. If it is still pending on October 1, cap-gap continues until a decision or April 1, whichever comes first. If it is denied, rejected or withdrawn, cap-gap ends. Your DSO's cap-gap I-20 shows the exact date.

Cap-gap usually applies when

• You are on valid post-completion OPT (including STEM OPT), and
• Your employer files a cap-subject H-1B petition requesting change of status, and
• USCIS receives that petition before your OPT EAD expires, and
• The petition is not immediately denied/rejected as not filed

Then F-1/OPT can extend to April 1 of the fiscal year (or your H-1B start date, if that is earlier). If the H-1B is approved, you change to H-1B on October 1 (or on approval if later).

Cap-gap usually does not apply when

Timing trap that kills “winners”

March: selected.
April–May: employer “working on it.”
June: EAD expires.
July: I-129 filed.

That sequence is how selected students still have to stop working. File before the EAD dies. Put the EAD end date on the attorney’s calendar in February.

Cap-gap and STEM pending / STEM approved

STEM OPT is still post-completion OPT. Cap-gap can run on top of STEM if the H-1B is timely filed while STEM/OPT is valid. Do not drop STEM reporting because you “already have cap-gap.” If the H-1B fails, you need STEM to still be clean.

Travel during cap-gap

High risk.

• Cap-gap authorization is not the same as an H-1B visa stamp.
• Re-entry as F-1 during cap-gap is a CBP/DSO/attorney question, not a blog question.
• Leaving while COS is pending can be treated as abandoning COS.

If you must travel, get written advice first. Default: do not travel June–September of a cap-gap year.

What to give HR for I-9 during cap-gap

Typically:

• Expired or soon-expiring OPT EAD
• I-94 / I-20
• I-797C receipt showing timely filed cap-subject H-1B COS
• USCIS cap-gap explanation

If HR says “we cannot employ you without a new card,” escalate with the attorney. Many I-9 officers have never seen cap-gap.

If you are not selected

Do this the week results come out, not in August.

1. Recalculate your remaining authorization

2. Backup paths (discuss with counsel; none are automatic)

Cap-exempt H-1B
University, certain nonprofits, affiliated research. Can start without waiting for October 1. Still a specialty occupation. Still an employer petition.

Different employer next year
If STEM remains, you can change jobs (new I-983) and try March again. A better specialty-occupation role is worth more than begging a non-sponsor.

Other nonimmigrant categories
O-1 (extraordinary ability), TN (limited nationalities), E-2 (treaty investor — you generally do not “get this” as a recent grad employee), L-1 (need a qualifying foreign employer relationship). Most F-1 students do not qualify. Do not pay a consultant who says otherwise.

New degree program
A legitimate full-time program can reset F-1. Day-1 CPT as an H-1B bridge is how people collect RFEs later. If the program is not a real degree you would do anyway, it is a trap.

Leave and return later
Consular H-1B in a future year if an employer still wants you. Ask the attorney about the $100,000 payment first (change of status vs consular processing). Optional, painful, sometimes cleaner than status violations.

Marriage-based or other independent status
Fact-specific. Not an H-1B strategy.

3. What you must not do after a loss

• Work after the EAD ends (“volunteer,” unpaid same job, 1099, “equity only”)
• Assume cap-gap applies to unselected people (it does not)
• Let unemployment days run to 90 / 150 while you “see what happens”
• Pay for a fake second registration next year
• Ghost your DSO

4. If you still have STEM: use the extra year like it is scarce

Next March is not guaranteed. You can lose again.

Use the extra months to:

• Move into a role that is easier to defend as specialty occupation
• Get on payroll of an employer who has filed H-1Bs, not one who has “talked about it”
• Keep I-983, validations, and pay stubs perfect
• Avoid third-party placement if you can

If you are selected, then the petition is denied or withdrawn

Cap-gap ends. Remaining OPT/STEM, if any, is what it is.

Same day:

• Notify DSO
• Stop work if no remaining EAD/STEM/cap-gap
• Ask attorney whether a motion, new filing, or consular path exists
• Do not keep working on “we will appeal”

A denial is not always the end of the career. It is the end of that employment authorization story until something new is approved.

Month-by-month: March 2027 lottery (May 2026 grad)

Jan 2027
Attorney retained. Job description vs degree. Wage level. Worksite. STEM I-983 aligned with H-1B duties if on STEM.

Feb 2027
Document pack complete. LCA draft. Confirm EAD end date vs likely I-129 file date. If EAD ends June, the petition cannot slip to July.

March 2027
Registration. Save confirmation.

April 2027
Selected → LCA + I-129 immediately. Not selected → STEM file if still possible; else backup list.

May–June 2027
Petition should already be receipted if you need cap-gap through the October 1 start. DSO gets the receipt. HR briefed on I-9.

Jul–Sep 2027
Cap-gap work if eligible. No travel by default. Watch for RFE deadlines.

Oct 1, 2027
H-1B COS start if approved. New I-9. Stop describing yourself as OPT.

Cap-gap vs grace period vs STEM pending (do not confuse them)

If two seem to overlap, the strictest work rule wins until an attorney says otherwise.

Travel during lottery season

Common ways this stage fails

1. Employer registers you and never files I-129
2. I-129 filed after EAD expiry → no cap-gap, work must stop
3. Assuming selection = you can start work in April
4. Assuming grace period = cap-gap
5. Multiple fake registrations
6. Client-site job that cannot survive an RFE
7. Level 1 wage + generic title
8. Travel during pending COS
9. Working after a denial because “HR said stay”
10. Not selected, then unpaid continuation of the same job
11. STEM reports ignored because “H-1B is in process”
12. DSO never given the I-797 receipt

FAQ: H-1B lottery and cap-gap

Does registering for the lottery give me extra OPT?
No.

Can I start H-1B as soon as I am selected?
No. Cap-subject new employment is October 1. Until then you need OPT, STEM, or cap-gap.

If I am not selected, do I get cap-gap anyway?
No. Cap-gap requires a timely filed cap-subject petition.

Can my friend file H-1B for me as a “company”?
If it is not a real job offer from a real employer, it is a bad case and possibly worse than a denial.

Two employers selected me. What now?
Only one petition should proceed as the job you will actually do. Talk to both attorneys immediately. You cannot work for both on one H-1B.

I was selected last year, did not file, can I reuse it?
No. Each fiscal year is a new registration.

Does master’s vs bachelor’s change lottery odds?
USCIS has used a regular cap plus a master’s cap in recent years, which can improve odds for U.S. master’s/PhD holders. Rules can change. Do not bet your life on a rumor about percentages. Read the current year USCIS notice.

Cap-gap EAD looks expired. Can I fly?
Default no. Get advice. I-9 at work and admission at the airport are different problems.

When do I tell my DSO?
When you have an I-797 receipt (selected and filed), and immediately if denied, withdrawn, or you lose employment.
