H-1B Lottery Process: How the Cap Selection Works

The H-1B lottery has changed three times in the last six years. If your memory of the process comes from 2018, or from a coworker who went through it in 2021, much of what you "know" is now out of date. This guide reflects the current beneficiary-centric system that has been in effect since FY2025.

The mechanics matter. Understanding how the lottery actually selects beneficiaries lets you stop chasing the wrong strategies (multi-registration through consultancies, gaming the master's cap, fake job offers) and focus on what really moves the needle: getting registered, registering early, and pairing the lottery with a cap-exempt backup plan.

The four phases of the lottery cycle

The H-1B cap cycle runs annually from March to October. Each step has hard deadlines and there is no path to recover from missing them.

Phase 1: Registration window (March 1–17)

Registered employers submit a $215 electronic registration for each beneficiary they intend to sponsor. The registration is intentionally short: basic biographical data, passport number, education level, and worksite location. No employment evidence is required at this stage.

Phase 2: Beneficiary-centric selection (late March)

USCIS runs the random lottery. Since FY2025, selection is beneficiary-centric, meaning the system selects unique individuals rather than registrations. If five employers register you, your odds are exactly the same as someone with one registration, but you can pick from any of the five if selected.

Phase 3: Petition filing (April 1 – June 30)

If selected, the employer has 90 days to file the full I-129 petition with all supporting evidence. The clock here is strict: a missed deadline is a forfeit.

Phase 4: Adjudication and start date (August – October 1)

USCIS reviews each petition. Premium processing ($2,805) guarantees a 15-business-day decision. Approved beneficiaries can begin H-1B employment on October 1, the first day of the federal fiscal year.

How the two-pool draw actually works

The lottery has two interconnected pools.

The advanced-degree (master's) pool

If you hold a US master's degree or higher from an accredited institution, you enter the advanced-degree pool first. USCIS selects beneficiaries from this pool to meet the 20,000 advanced-degree allocation.

The regular pool

All registrations, including unselected master's-pool candidates, then compete for the 65,000 regular cap slots. This is why holding a US master's gives you "two chances": you compete in both pools.

The numbers in plain terms

• Bachelor's degree: One draw, ~25-30% odds.
• US master's or higher: Two draws, ~40-50% odds.
• Foreign master's: Same as bachelor's. The advanced-degree allocation is specifically for US-issued degrees.

Why the FY2025 reform mattered

Before FY2025, lottery selection was per-registration. Consultancies discovered they could register one beneficiary through dozens of shell sponsors, dramatically increasing odds. By FY2024 this had pushed registration volume to nearly 800,000. For 85,000 slots.

The beneficiary-centric reform broke this loophole. Registration volume dropped to roughly 480,000 in FY2025 and held similar in FY2026. The effect: genuine candidates' odds roughly doubled overnight, and consultancy-pumped numbers collapsed.

Second-round selections

If USCIS doesn't receive enough complete petitions by the June 30 deadline from the first round of selections, they run a second-round lottery in late July or August from the unselected pool. This has happened in 3 of the last 5 fiscal years. Your registration remains valid for the second round automatically. No action needed.

What you can (and can't) do to improve your odds

Things that genuinely help

• Earn a US master's. The advanced-degree pool is the single biggest leverage point.
• Apply broadly. Having an offer with a registered, willing employer is the prerequisite to any odds at all.
• Line up a cap-exempt fallback at a university hospital or research institute.

Things that don't help anymore

• Multiple registrations through consultancies. The beneficiary-centric reform killed this.
• "Guaranteed selection" services. They're selling something that no longer exists.
• Registering at multiple employers as backup. Same beneficiary, same odds.

If you're not selected

You have meaningful options. STEM OPT students can request a 24-month extension if they haven't already, giving themselves another lottery cycle. Cap-exempt employment lets you build H-1B status entirely outside the lottery. Some workers pivot to O-1, L-1, or L-1B paths. See our denial and next steps guide for details.

What the new rules mean for real candidates

Take Priya, a software engineer at a Series B AI startup in San Francisco. She was selected on her third registration. Her first two attempts came under the old per-registration system; her third was under the beneficiary-centric reform.

"The first two years I worked at consultancies that registered me through three different sponsor entities each. I thought the math was on my side. After the 2024 reform, I switched to a direct hire and registered with just one employer. My odds actually went up, and I was finally selected. The 'gaming' approach was a story consultancies told themselves; the math never worked the way they claimed."

Takeaway: Multiple registrations no longer help. Register once with a legitimate sponsor and prepare a cap-exempt fallback while you wait.
