Verified Employer Sponsorship Data Sources for H-1B Job Seekers

H-1B sponsorship research starts with the two government sources behind a “top sponsors” ranking. The Department of Labor’s LCA disclosure data shows what employers plan to file, while the USCIS H-1B Employer Data Hub shows how their petitions turned out. Read together, they give job seekers a more useful employer shortlist than either source alone, especially when the search is narrowed to a role, location, and wage level.

Why every H-1B sponsor list online traces back to the same two government sources

Two sponsor websites can give different counts for the same employer even when they use exactly the same federal records. Nearly every circulating list repackages the DOL Office of Foreign Labor Certification LCA disclosure files, the USCIS hub, or both. The differences often come from update schedules and decisions about matching subsidiaries to parent companies.

Both government datasets are free, follow official release schedules, and can be searched without a login. Aggregators make them easier to browse, but introduce another publication cycle between the filing record and the reader. Going directly to the originals removes that delay and lets a job seeker filter for a particular occupation and city.

What the DOL LCA disclosure data actually contains and what it measures

The DOL disclosure files provide the most granular public record of H-1B hiring intent. They cover Labor Condition Applications for H-1B, H-1B1, and E-3 petitions across final determination statuses, including Certified, Certified-Withdrawn, Withdrawn, and Denied. The distinction between those statuses is essential. A file of applications is not a list of successful hires.

Each row includes the employer name and FEIN, SOC occupation code, job title, prevailing wage source, offered wage, full-time or part-time status, and worksite geography. The wage-level field runs from I through IV and helps sort filings by the role’s wage classification. It becomes useful when matching an employer’s activity to a candidate’s seniority. DOL publishes the files quarterly, with the latest release described here covering determinations issued between October 1, 2025 and June 30, 2026.

An LCA comes before a petition to USCIS. Certification means only that DOL accepted the employer’s wage and working-condition attestation. Yet the record is still useful because it puts offered wage, occupation code, and worksite location together in one row. That combination supports wage benchmarking and location filtering in a way employer-level approval totals cannot.

The FLAG system serves a narrower purpose. Employers file LCAs there, and a case number can be used to verify status, but employer discovery requires the disclosure files. FLAG’s prevailing wage search also provides a wage-floor check for a given occupation and location. An offer below the applicable floor cannot be legally sponsored at that salary.

What the USCIS H-1B Employer Data Hub actually contains and what it measures

The USCIS hub reports employer petition approvals and denials from fiscal year 2009 through the present. It therefore answers a question the LCA files cannot answer. Searches by employer name, state, and NAICS industry code help narrow the field, while the results separate initial employment from continuing employment outcomes.

“New Employment Approvals” is the crucial column for new-hire research. Continuing employment counts reflect renewals and do not establish willingness to sponsor a new hire. An employer can have substantial sponsorship activity without offering the kind of opportunity a candidate needs. Reading only the total obscures that distinction.

These counts are adjudication snapshots attached to legal entities. Subsidiaries may appear separately, so one entry can understate a corporate family’s combined activity. Because of when decisions are made, one strong year does not prove that an employer keeps hiring at that rate. Several fiscal years provide a more reliable pattern. When an aggregator’s figures and DOL filing counts disagree about outcomes, the hub is the tie-breaker because it records petition decisions.

How the two datasets differ and why both are needed

The two datasets describe different stages of sponsorship. LCA records show recent activity for a role, worksite, and wage range, while the hub shows whether petitions have succeeded over time. Neither can stand in for the other. Treating a filing as an approval exaggerates results, while treating past approvals as current hiring intent overlooks changes in employer demand.

That difference in stages explains why LCA counts can be several times higher than USCIS approval counts for the same employer. Multiple LCAs can precede a single petition, and the LCA records include renewals, transfers, and cases that never reach approval. Many do not lead to a new-hire petition at all.

A high LCA count paired with few new employment approvals nevertheless deserves investigation. Examining several years of petition history is a useful response. Matching names takes just as much care because subsidiaries, name changes, and DBAs can make two records look as though they belong to different employers. The hub’s legal entity names provide the stronger anchor when the match is uncertain. Before interpreting a discrepancy, establish that the records describe the same employer.

How to build a targeted employer shortlist from these two sources for a specific role and location

For a practical search, start in the hub with the NAICS code for your industry and your target state. Sort by new employment approvals in descending order, then review multiple years for consistency. This narrows the field to sponsors in your sector.

Next, check those employers against recent certified LCAs for your SOC code and target metro area. A company with many approvals two years ago but no recent filings in your field may have changed its hiring pattern. Apply the wage-level filter to sharpen that match. For an experienced professional, Level III or IV filings in the target metro area can identify employers whose recent activity aligns with seniority. Under the wage-weighted lottery that took effect February 27, 2026, those higher wage levels also get more entries.

The next check extends beyond temporary sponsorship. DOL’s PERM disclosure data shows which employers are filing for permanent residence, a sign that they are willing to sponsor workers for the longer term as well as through H-1B. If an offer is already on the table, use FLAG to compare the salary with the prevailing wage for the occupation and location. Even an employer with high totals in past years cannot sponsor a worker at a salary that is too low for certification.

Then establish whether the position is cap-exempt. Universities, nonprofit entities affiliated with higher education institutions, and qualifying nonprofit and governmental research organizations can file year-round under INA 214(g)(5) without going through the lottery. DHS’s modernization rule, effective January 17, 2025, broadened the research-organization definitions. Confirm the exemption directly with the employer’s HR team. Finally, check current company news for layoffs, hiring freezes, or changes in willingness to sponsor that have yet to show up in the records.

What recent rule changes mean for reading the data in 2026

The cost and selection environment has changed. DHS’s final rule, effective February 27, 2026, replaced random selection with wage-weighted selection, giving each unique beneficiary one entry at Level I, two at Level II, three at Level III, and four at Level IV. As a result, past filing counts alone say less about an employer’s chances in the current cycle.

The FY2027 registration period ran March 4–19, 2026. USCIS completed selection on March 31 and confirmed on July 17 that the cap had been reached with no second round. Total registrations reportedly fell, and most of the selected beneficiaries had U.S. advanced degrees. These results belong to the changed selection environment. They should not be treated as a simple continuation of earlier years.

The fee history requires a separate timeline. Proclamation 10973, dated September 19, 2025, required a $100,000 payment for certain new petitions involving individuals outside the United States. A Massachusetts federal court vacated the implementing policies on June 8, 2026, and the First Circuit refused a stay on July 24. A new proclamation signed September 18 extended the payment requirement to September 21, 2027. However, a California federal court barred enforcement of agency policies under both proclamations on September 30 pending notice-and-comment rulemaking, and USCIS was not collecting the payment as of late October 2026.

DHS separately proposed a $103,265 fee on August 24, 2026, for all cap-subject petitions, payable at filing in addition to existing fees. That proposal, still pending, would apply to higher education institutions and nonprofit and governmental research organizations when they file cap-subject petitions. The fee would not apply to their cap-exempt petitions.

Initial petitions received for consular processing from cap-exempt employers dropped sharply during the first eight months the $100,000 payment was in effect. Earlier filing totals do not reflect that response. For current employer research, give FY2025–FY2026 more weight than earlier years. Declining new employment approvals after heavy filing in FY2022–FY2023 may reflect the cost environment.

Where third-party aggregators fit in once you understand the primary sources

Aggregators can save substantial browsing time. H1BVisaJobs.com aggregates employers with certified LCAs and supplements hub data with state and wage-level detail across FY2021–FY2026. Wisa offers searches by company name, job category, state, and city, with filing counts, the most recent filing year, and a composite sponsor score. These tools make records easier to navigate. Their convenience does not create a separate source of evidence.

Freshness and name matching determine how useful the results are. Some tools follow DOL’s quarterly schedule, while others sync with USCIS releases, so an older snapshot can produce a different employer ranking. Grouping also changes the view. An aggregator that combines Amazon subsidiary filings under “Amazon” answers a different question from one that preserves every legal entity. Both ways of grouping the records can work, but the totals cannot be compared directly.

The practical workflow is to use an aggregator for a quick candidate list, then verify serious prospects against the government records before investing in applications. Platforms for international job seekers address a related problem by connecting open roles to employers with recorded sponsorship histories. That can reduce manual cross-referencing during a search. It still does not turn an employer’s history into a commitment for a particular vacancy.

The limits of public sponsorship data and what to verify directly with employers

Public records cannot show whether a company has the budget, legal team, or hiring policy to sponsor you for your particular role now. Large employers may have business units or legal entities that sponsor and others that do not. A parent-company total cannot settle that question. Nor can a historical record override a posting that explicitly says “no sponsorship,” especially when some previously active employers have reduced new-hire sponsorship in response to the fee environment.

Eligibility should be verified early in the recruiter conversation. Ask whether the role supports H-1B sponsorship, whether the petition would be cap-subject or cap-exempt, and who pays legal and filing costs. Get the answer in writing, tied to the role and petition type. A verbal “we sponsor” is not that commitment.

Correctly read sponsorship history is a better guide to application effort than name recognition, job title, or an unverified recruiter claim. Use the two datasets to identify employers with relevant recent filings and a record of approvals, then ask those employers about the actual position. The data identifies where to direct effort. The employer must confirm whether it can sponsor the role.
