H-1B Lottery Odds & Multiple Registration Strategy Tool

Estimate H-1B cap selection odds under the season’s registration rules

H-1B cap planning starts with a practical question: with this season’s registration volume, what is one beneficiary’s estimated chance of selection? This calculator estimates regular-cap odds, adds the advanced-degree opportunity when applicable, and changes its treatment by season. FY 2025 and FY 2026 use beneficiary-centric random selection; FY 2027 and later use this page’s educational wage-level-weighted model.

The rule distinction is central to an H-1B registration strategy. Several employers registering the same beneficiary do not multiply that beneficiary’s modeled odds in the beneficiary-centric approach. In the FY 2027+ weighted scenario, registrations for the same beneficiary with different equivalent wage levels are modeled at the lowest equivalent wage level.

The percentage shown here is an estimate rather than a selection guarantee. USCIS mechanics, later selection rounds, duplicate review, petition denials, and other real-world events can affect outcomes beyond a compact registration-pool model. The calculation is nevertheless useful for comparing seasons, showing why an advanced-degree beneficiary generally has a higher estimated chance than a regular-cap-only beneficiary, and illustrating why additional employers mattered more under the earlier multi-entry framework. It is a planning reference for beneficiaries, employers, recruiters, and readers interpreting H-1B lottery statistics.

H-1B registration-pool and cap inputs explained

Total General-Cap Registrations is the full pool used for the regular 65,000-cap calculation. Enter eligible registrations competing for regular-cap slots in the season being modeled. Advanced-degree registrations are included here because they are considered in the general draw before eligible unselected registrations proceed to the additional advanced-degree draw. This is generally the total registration figure reported in seasonal USCIS coverage.

Total Advanced-Degree Registrations (subset of general) identifies the portion of that total pool eligible for the advanced-degree exemption. It must be no larger than the general pool because it is contained within it. This input represents registrants who can receive a second modeled opportunity after the general draw. A larger advanced-degree pool increases competition for the additional 20,000 selections, while a smaller remaining pool raises the estimated chance in that round.

Number of Employers Filing for You is used to compare registration frameworks. In the legacy comparison, the calculator treats filings as independent entries and applies a complement probability calculation to show how another filing could have changed the estimated chance. In the FY 2025/FY 2026 beneficiary-centric and FY 2027+ weighted models, the field does not boost the current beneficiary probability. Entering two, three, or four employers therefore illustrates the historical contrast rather than a current-season advantage.

Do you qualify for the advanced-degree exemption? should be set to yes only for a beneficiary who qualifies for the advanced-degree scenario being evaluated. With the setting on, the model places the person in the general cap first and, if not selected, estimates an additional advanced-degree-cap chance. With it off, only the regular-cap chance is used.

Season selects the H-1B policy model used by the calculator. FY 2025 and FY 2026 use beneficiary-centric random selection. FY 2027+ applies equivalent wage-level weighting in this educational model, so higher wage levels receive higher modeled odds. Verify current USCIS instructions before relying on any scenario for filing decisions.

General Cap Slots and Advanced-Degree Cap Slots define the number of modeled selections in each stage. Their defaults reflect the familiar 65,000 regular-cap and 20,000 advanced-degree-cap structure. The fields remain editable for hypothetical policy or explanatory scenarios; they are not a forecast or a recommendation to alter a filing plan.

For uncertain registration counts, run separate H-1B scenarios rather than treating one percentage as exact. One run can use the latest verifiable total, while another can use a more crowded pool. Comparing those outputs makes the impact of registration volume visible.

How this H-1B odds model calculates regular and advanced-degree selection

The H-1B calculation begins with the regular-cap single-entry probability: general-cap slots divided by the general registration pool. The calculator clamps this value from 0 to 1 so an unusual input combination cannot produce a percentage above 100%.

Here, G is the total general registration pool and C_general is the number of regular-cap slots. For example, 343,981 general registrations and 65,000 general-cap slots produce a regular-cap single-entry estimate of about 18.9%.

For an advanced-degree-eligible beneficiary, the H-1B model estimates the number of advanced-degree registrations expected to be selected in the general draw. It subtracts that expected count from the advanced-degree pool, then uses the remainder as the estimated pool for the additional cap. The combined probability includes selection in the general draw plus selection in the advanced-degree draw after missing the general draw.

In this H-1B expression, M is the advanced-degree registration pool and C_masters is the number of advanced-degree-cap slots. The approach is deliberately simplified: it uses an expected remaining pool rather than simulating every possible sequence of lottery selections. That makes the result easier to inspect as a planning estimate.

The next H-1B step depends on the selected framework. For a legacy comparison in which multiple employer registrations are treated as independent chances, the calculator uses the complement formula below. Here, n is the number of employers and p is the applicable single-entry probability.

In beneficiary-centric and FY 2027+ H-1B modes, the calculator intentionally does not add a same-beneficiary multi-registration increase. The model retains one beneficiary probability, with the FY 2027+ scenario adjusting that probability by equivalent wage level.

The result therefore depends on identifiable H-1B variables rather than a generic score: registration-pool size, cap size, advanced-degree eligibility, selected season, and, in the FY 2027+ educational scenario, the effective equivalent wage level.

H-1B default-volume example: regular cap, master’s cap, and legacy entries

Using the FY 2026 defaults gives a concrete H-1B comparison: 343,981 general-cap registrations, 150,000 advanced-degree registrations within that total, 65,000 general-cap slots, and 20,000 advanced-degree-cap slots. A regular-cap-only beneficiary begins with 65,000 divided by 343,981, or about 18.9%. With one employer, that is the FY 2026 single-beneficiary estimate. Under the historical independent-entry comparison, three employers would produce roughly 46.7%, but the FY 2026 beneficiary-centric result remains the one-beneficiary percentage.

For an advanced-degree-eligible H-1B beneficiary using those same counts, the model estimates that about 28,344 advanced-degree registrations are selected in the general draw. About 121,656 then remain for the 20,000 advanced-degree-cap slots. The second-stage chance is about 16.4%, and it applies only after missing the general draw. Combining both stages yields an estimated advanced-degree single-entry probability of about 32.2%, subject to display rounding.

The important H-1B interpretation is that advanced-degree registrants do not begin in a wholly separate lottery. They first compete in the regular-cap selection with other eligible registrants, then may receive an additional advanced-degree opportunity if unselected. The combined estimate is thus higher than the regular-cap estimate, but it is not the simple addition of 18.9% and 16.4%.

This H-1B table is an interpretation aid, not a filing recommendation. If changing a single pool or cap value moves the estimate in the expected direction, the scenario is reflecting the model’s stated relationships. If a result appears surprising, first confirm that the advanced-degree count is a subset of the general count and that the selected season matches the intended rule environment.

Reading an H-1B selection estimate responsibly

When you select Calculate Odds, the result panel gives an H-1B-specific summary beginning with the single-entry estimate. With advanced-degree eligibility enabled, that figure reflects the model’s two-stage general-cap and advanced-degree-cap opportunity. With it disabled, it is the regular-cap probability alone.

The next part of the H-1B summary explains whether employer count affects the selected framework. In FY 2025, FY 2026, and FY 2027+ modes, it should state that additional employers do not raise the modeled current-season odds for the same beneficiary. If four employers still produce the same current beneficiary probability, the calculator is applying its intended rule. The optional pre-2025 comparison remains available to demonstrate how independent-entry math differed.

Test H-1B assumptions one at a time for the clearest interpretation. Hold the pools constant while switching advanced-degree eligibility, then hold candidate status constant while changing seasons. Finally, change registration-pool totals to see the effect of a more or less crowded cap season. This isolates the reason an estimate changes.

Simple direction checks are especially useful for H-1B inputs. Increasing general registrations while leaving cap sizes unchanged should lower odds. Increasing cap sizes with unchanged pools should raise odds. In legacy mode, increasing employer count should raise the independent-entry comparison with diminishing incremental gains. These checks can identify an entered count that does not belong to the scenario.

H-1B model assumptions, boundary cases, and limitations

This H-1B tool is intentionally compact and makes several assumptions that matter when interpreting its output:

• The advanced-degree pool is assumed to be a subset of the general pool. A master's pool larger than the general pool does not describe the lottery structure modeled here.
• Legacy multiple filings are treated as independent chances. This supports a historical comparison but does not reproduce every procedural feature of past registration seasons.
• The advanced-degree round uses an expected remaining registration count. The calculator does not perform a full stochastic simulation of each possible draw order.
• The tool does not estimate later rounds, denial rates, or petition-stage approval. It models registration-stage selection probability only.
• The output is educational and strategic, not legal advice. Filing compliance, beneficiary eligibility, and current USCIS rules require confirmation from authoritative sources.

These H-1B limitations make the estimate transparent rather than less useful. Knowing which inputs control the number helps a beneficiary, employer, manager, or client understand the scenario and decide whether additional legal or statistical analysis is needed. For routine cap-planning discussions, an inspectable model is often more useful than an unexplained percentage.

The optional H-1B visual exercise below illustrates the policy distinction without affecting any calculation above. It depicts why multiple registrations could resemble additional chances in a legacy scenario and why the unique-beneficiary approach reduces them to one beneficiary opportunity.
