FY2027 H-1B Lottery: Registration Window, Selection Odds, and What the Numbers Say

FY2027 H-1B lottery registration opens in March — here is exactly what your selection odds look like based on recent USCIS data and what you should do before and after results come out.

Every March, hundreds of thousands of international professionals on F-1, OPT, and STEM OPT hold their breath for two weeks while their employers submit H-1B pre-registrations to USCIS. You've done everything right — found a sponsoring employer, stayed in status, cleared your degree verification — and now the outcome depends on a random-selection lottery you have almost no control over. That disconnect between effort and outcome is the defining anxiety of early-career immigration in the United States.

Understanding the lottery mechanics, the numbers behind selection probability, and what actually determines your odds is the first step toward managing that anxiety productively. More importantly, knowing what to do before the window closes — and exactly what to do if you're not selected — means the lottery is a data point in your strategy, not a cliff you fall off.

How the FY2027 H-1B cap lottery works

The H-1B program is capped by statute at 65,000 new cap-subject visas per fiscal year (the "regular cap"), with a separate 20,000 additional slots reserved for beneficiaries who hold a U.S. master's degree or higher (the "master's-degree-exempt" pool, also called the advanced-degree exemption). Together these make up the roughly 85,000 cap-subject H-1B slots available each fiscal year.

Pre-registration, not petitions

Since FY2020, USCIS has used an electronic pre-registration system rather than accepting full petitions at the lottery stage. Employers pay a $215 registration fee per beneficiary (as of the 2026 USCIS fee schedule) and submit a short registration during the designated window. No full petition, no attorney fees for unselected candidates — just a registration.

If selected, the employer then has a 90-day window to file the actual I-129 petition, which includes the Labor Condition Application (LCA) certified by the Department of Labor, documentation of specialty-occupation status, and supporting evidence.

The two-pool system

USCIS runs selection in a specific order:

1. All registrations are first entered into the master's-degree-exempt pool if the beneficiary holds a U.S. master's or higher. USCIS selects enough to fill the 20,000 advanced-degree slots.
2. Unselected registrations from step one, plus all regular-cap-only registrations, are pooled for the 65,000 regular-cap selection.

The practical effect: a U.S. master's or higher gives you two chances at selection in a single cycle. If you're selected in step one you're done. If not, you roll into the larger pool for step two. A candidate without a U.S. master's only has one shot (step two). This is why the wage-weighted lottery proposal — which would prioritize higher-wage positions — has generated so much debate; it would change this math significantly.

FY2027 registration window and key dates

USCIS has followed a consistent calendar in recent years:

USCIS posts exact dates on its website before the window opens. Your employer's immigration attorney or HR team should be tracking this; if you're managing your own process, set a reminder for early March and monitor the USCIS H-1B landing page directly.

Critical: you cannot self-register. Only an employer with an active USCIS online account can submit a registration on your behalf. If you're in final-round interviews with a company in February, push to get an offer closed before the registration window so they can register you. A verbal "we plan to sponsor you" is not enough — the employer must actually submit and pay for the registration.

What the selection numbers actually say

USCIS publishes registration data after each lottery cycle. Here is what recent cycles show (approximate figures from USCIS public disclosures):

A few important caveats on these numbers:

• FY2024 saw an enormous spike driven in part by multiple registrations per beneficiary from staffing firms. USCIS implemented a beneficiary-centric selection rule starting FY2025, meaning each unique beneficiary (identified by passport number) can only be selected once per lottery cycle even if multiple employers registered them. This caused the FY2025 number to drop significantly.
• USCIS may conduct supplemental selection rounds if approved petitions fall short of the cap due to withdrawals, denials, or unfiled petitions. Supplemental rounds have occurred in FY2022, FY2023, and FY2025.
• "Selection rate" above is approximate. The master's-exempt pool has a higher effective selection rate per registration, and the overall blended rate depends on the mix of master's vs. regular-cap registrations.

For FY2027, we do not yet have actual registration counts. The numbers will be published by USCIS after the window closes. Based on recent trends, expect something in the 350,000–500,000 range for unique registrations, which would put overall selection odds somewhere between 17 and 25 percent. If you hold a U.S. master's degree, your effective odds are meaningfully higher due to the two-pool system.

How a U.S. master's degree changes your math

If you earned a master's degree in the US, run through this logic:

• You enter the master's-exempt pool first (20,000 slots)
• If selected there, you're done — you proceed to the full petition
• If not selected (say roughly 75–80% of master's-pool registrations are unselected, depending on volume), your registration automatically rolls into the regular 65,000 cap pool for a second draw

This means your overall selection probability is approximately:

P(selected) = P(selected in master's pool) + P(not selected in master's pool) × P(selected in regular cap pool)

Even with conservative estimates for each pool, a U.S. master's holder's overall odds are meaningfully higher than a regular-cap-only candidate's odds. This is one reason that domestic master's programs — particularly STEM-designated programs qualifying for the 24-month STEM OPT extension — remain popular among international professionals optimizing for H-1B odds.

What cap-exempt means for your situation

If you're employed by or have an offer from a cap-exempt employer, the lottery does not apply to you at all. Cap-exempt H-1B petitions can be filed at any time of year, with no random selection, and employment can start as soon as the petition is approved.

Cap-exempt employers include:

• Institutions of higher education (universities and colleges)
• Nonprofit entities related to or affiliated with institutions of higher education
• Nonprofit research organizations and government research organizations

This covers the overwhelming majority of universities, many teaching hospitals (when structured as nonprofit affiliates of a university), national laboratories affiliated with universities, and certain government-funded research centers. A detailed breakdown is in our cap-exempt employers guide.

The career tradeoff is real: cap-exempt roles typically pay less than their industry equivalents, and the immigration security is higher. If you're a researcher, postdoc, or academic considering the research scientist path, working through the cap-exempt route can be a rational way to bridge to permanent residence without depending on lottery luck.

What happens during cap-gap if you're on OPT

If you're on F-1 OPT when your employer registers you and you're selected, you'll rely on cap-gap coverage to maintain work authorization between OPT expiration and the October 1 H-1B start date. Here's the critical timeline:

1. Your OPT EAD expires at some point between the petition filing (April onward) and October 1
2. If a timely-filed, non-frivolous H-1B petition is pending on your behalf, USCIS automatically extends your F-1 status and OPT work authorization through September 30 — this is the cap-gap period
3. On October 1, your H-1B status activates (if approved), or if still pending, you remain covered until a final decision

The cap-gap explanation is more detailed in our cap-gap guide. Key point here: do not travel internationally during cap-gap without confirming reentry will work. Your F-1 visa stamp and OPT EAD may be expired; reentry on cap-gap is legally possible but practically complicated. This is covered in detail in the cap-gap travel risks guide.

If you're on STEM OPT, the 90-day unemployment limit still applies — you must maintain the qualifying employment relationship (F-1/EAD with the sponsoring employer) throughout. Do not let that clock run during any period when you're awaiting the lottery outcome.

Step-by-step timeline to maximize your FY2027 lottery position

1. Now through February 2026: Secure a sponsoring employer. A company that has never sponsored before still can — walk them through the USCIS employer registration process, which involves creating a myUSCIS organizational account. Use our checklist on whether a startup can sponsor to evaluate the employer's viability.

2. Early March 2026: Confirm your employer has submitted registration before the window closes. Get a copy of your registration receipt. Know your exact passport number and visa status, as this is how USCIS de-duplicates beneficiaries.

3. Mid-to-late March 2026: Registration window closes. USCIS begins the random selection process.

4. Late March or April 2026: Selection notifications go to the employer's myUSCIS account. If selected, you and your employer are notified and begin preparing the full I-129 petition.

5. April–June 2026: Attorney prepares and files I-129 petition, LCA certified by DOL, within the 90-day filing window. Premium processing ($2,965, 15-business-day guarantee) is available here and strongly recommended if your OPT expires before October or if any status gap is possible.

6. Late spring through September 2026: USCIS adjudicates. Watch for Requests for Evidence (RFEs). Read the RFE response playbook if you receive one.

7. October 1, 2026: H-1B status activates. FY2027 begins.

Common mistakes

Waiting too long to get an offer. The registration window is fixed and short. Companies that haven't set up their myUSCIS account cannot register during the window even if they want to. If you're graduating in May or June and are counting on the lottery, you need an offer from an employer who is already set up before March.

Assuming multiple registrations help you now. Since FY2025, the beneficiary-centric selection rule means multiple employers registering you does not improve odds for the regular cap selection — you will only be selected once per unique beneficiary identifier per cycle. Multiple registrations still make sense if genuinely different employers may file different petitions and you want to preserve optionality, but gaming selection probability with registrations from staffing firms or shell arrangements no longer works.

Not having a backup plan ready before results. USCIS announces selection results and then you have weeks — not months — to decide on alternatives. Have your backup plans sketched out before the lottery results land so you are not making panicked decisions in April.

Confusing registration with petition filing. Being selected in the lottery means USCIS has authorized your employer to file the H-1B petition. The petition still needs to be filed, the LCA certified, and the case adjudicated. A lottery selection is not an approved H-1B.

Missing the 90-day petition filing deadline. Selected registrations must result in a filed petition within 90 days of the selection notice. If your employer misses this deadline — for any reason — your selection is voided and you must wait for the next fiscal year's lottery.

Not understanding cap-exempt options before the lottery. Many candidates who end up at hospitals, universities, or nonprofit research organizations never needed to worry about the lottery at all. If you are already in one of those environments or have a realistic path to an offer there, explore the cap-exempt route before spending anxiety on lottery odds.

Traveling internationally on cap-gap without a plan. Your ability to reenter the US on expired OPT and a pending H-1B is real but delicate. Do not book international travel between April and October 1 without consulting an attorney first.

If you're not selected: what now

If the FY2027 lottery does not select you, your legal options depend on your current status:

• Still on OPT or STEM OPT: Continue in that status, and have your employer register you in the FY2028 lottery (March 2027). On STEM OPT you may have another one to three years of authorized work remaining.
• O-1A visa: If your work history, compensation, publications, or recognized contributions are strong, an O-1A petition can be filed at any time of year with no lottery. The evidentiary bar is high but lower than many people assume. See the O-1 complete guide.
• Cap-exempt employer: Move to a university, nonprofit research organization, or teaching hospital. These employers can file your H-1B at any time.
• TN visa: Canadian and Mexican nationals can work in certain professional categories under TN status, which requires no lottery and can be obtained at the port of entry. See the TN visa guide.
• L-1 intracompany transfer: If your employer has international offices and you can work abroad for at least one year, you may qualify for an L-1 petition on return.
• Continue building your EB case: Some candidates — particularly researchers — are eligible for an EB-2 NIW self-petition without waiting for H-1B approval.

Not being selected is genuinely frustrating and the stakes are real. But more people find a workable path than you might expect from the forums, where the loudest voices are the most panicked ones.

Frequently asked questions

When does FY2027 H-1B lottery registration open and close?

USCIS typically opens the H-1B electronic pre-registration window for a roughly two-week period in early-to-mid March each year. For FY2027, registration is expected to run in March 2026. USCIS announces the exact dates on its website, and you must have a sponsoring employer submit the registration on your behalf — you cannot self-register.

What are the realistic selection odds for the FY2027 H-1B lottery?

Selection odds depend on how many registrations are submitted and the number of slots available (65,000 regular cap plus 20,000 U.S. master's-degree exempt). In recent years USCIS received several hundred thousand unique registrations for roughly 85,000 available slots. Rough probability for the regular cap has run between 20 and 35 percent in recent cycles, though the exact FY2027 figure will not be known until USCIS publishes its post-registration data later in 2026.

Does holding a U.S. master's degree improve my H-1B lottery odds?

Yes. If your highest U.S. degree is a master's or higher, your employer can enter you in the master's-degree-exempt pool (20,000 additional slots) first. Any unselected registrations from that pool roll into the regular 65,000-slot cap lottery. In practice this gives you two chances to be selected in a single registration cycle, which meaningfully improves overall odds compared to the regular cap only.

How many H-1B petitions are selected each year and when are results announced?

USCIS selects enough registrations to fill approximately 85,000 cap-subject slots (65,000 regular plus 20,000 master's-exempt). Selection notifications are sent to employers' USCIS online accounts, typically in late March or April. If initial selection falls short, USCIS may conduct additional selection rounds later in the fiscal year.

What should I do if I am not selected in the FY2027 H-1B lottery?

Not being selected does not end your options. You can continue on OPT or STEM OPT while your employer re-enters you in future lotteries. Cap-exempt employers such as universities and nonprofit research organizations are not subject to the lottery at all. Other pathways include the O-1A visa for individuals with extraordinary ability, the TN visa for Canadian and Mexican nationals, or the L-1 intracompany-transfer visa. A detailed breakdown of post-lottery options is covered in our backup plans guide.
