Search the employer’s exact legal entity, compare several fiscal years, and keep the two stages separate. An LCA shows labor-condition filing activity; a USCIS approval or denial shows a decision on an H-1B petition. Neither proves that the employer has an open job, will sponsor you, or that a petition will be approved.
What the two official datasets actually tell you
H-1B sponsorship leaves records at different points in the process. An employer generally needs a certified LCA before submitting the related H-1B petition to USCIS. Because the records describe different stages, combining them without labeling the stage can make a company look more active—or more successful—than the evidence supports.

| Source | Record | What it can establish | What it cannot establish by itself |
|---|---|---|---|
| DOL OFLC Performance Data | LCA application and final OFLC determination | The employer filed labor-condition paperwork for a listed occupation, wage, and worksite; the file’s status field describes the OFLC determination. | That USCIS received a petition, approved it, hired a worker, or will sponsor a particular applicant. |
| USCIS H-1B Employer Data Hub | First recorded approval or denial decision on an H-1B petition | Historical adjudication activity, separated into initial and continuing employment categories and grouped by fiscal year and employer/location fields. | A current vacancy, a pending case, a later appeal or revocation outcome, a visa stamp, or a promise of future sponsorship. |
DOL’s disclosure program covers H-1B, H-1B1, and E-3 records. Therefore, do not call every LCA row an H-1B filing unless the program and other fields identify it as such. USCIS’s Hub is the more direct source for adjudicated H-1B petition decisions, but it has its own counting rules and data-quality warnings.

Step 1: Identify the legal employer before searching
Begin with the legal entity, not the brand name displayed on a careers page. Copy the employer name from the offer letter, job posting’s legal notice, application portal, or company’s official employment information. Record punctuation, abbreviations, former names, and the location shown for the role.
#1 Best Overall
Make a small identity sheet before opening either database:
- Exact legal name and likely spelling variants.
- Parent company, subsidiary, acquired company, or professional-services entity, if the relationship is documented.
- Employer identification or tax ID, when available from a filing or an employer-provided record.
- City, state, ZIP code, and the worksite associated with the position.
- Whether a staffing firm, consulting firm, or client appears to be the petitioner or worksite.
Search each plausible name separately. A staffing company may file the petition while a client appears as the worksite; a parent and subsidiary may have different tax IDs. Do not merge rows merely because their names look similar. If you cannot establish that two entities are the same legal employer, report the match as unresolved rather than adding the records together.
Step 2: Search DOL’s OFLC disclosure files
Use the DOL Performance Data page and open the LCA disclosure files for the fiscal years you want to examine. The page publishes quarterly and annual files plus a record layout explaining the columns. The latest material identified for this article was the FY2026 Q3 release, covering final determinations from October 1, 2025 through June 30, 2026; an August 14, 2026 announcement described that release. A quarter is not a full fiscal year, so label it as partial when you use it.
- Choose a comparable period. Download the same type of file for each year—quarterly with quarterly, or annual with annual. Keep a note of the fiscal-year and quarter coverage.
- Read the record layout first. Confirm the fields for employer name, case status or determination, occupation, wage, worksite, and any program indicator. Older files may have originated in the iCERT system before the FLAG system, so field formats are not necessarily identical across years.
- Filter by employer name and variants. Search the exact legal name, then documented variants. Preserve the original spelling in your notes so another person can reproduce the search.
- Check the program and status fields. Separate H-1B records from H-1B1 and E-3 where the file provides that distinction. Describe the result as an LCA filing or LCA determination, not an “approved visa.”
- Inspect the role and location. Compare the occupation, wage information, and worksite with the job you are considering. A record for a different occupation or state may belong to another business unit or client assignment.
- Save the coverage date and row-level evidence. Keep the fiscal year or quarter, employer spelling, worksite, occupation, wage fields, and determination status with your notes. This prevents a partial-year result from being mistaken for an annual total.
DOL describes these files as selected administrative information from employer applications and final OFLC determinations. A certified LCA is an antecedent filing: it is required before the employer can petition USCIS, but it is not proof that the petition was filed or approved.
Step 3: Search the USCIS H-1B Employer Data Hub
Open the USCIS H-1B Employer Data Hub and search by employer name. The Hub also supports fiscal year, two-digit NAICS code, city, state, ZIP code, and tax ID filters. USCIS provides downloadable annual files if you need to analyze many employers or preserve a reproducible copy.
- Start broad, then narrow. Search the exact legal name without a location filter. Add city, state, ZIP, NAICS code, or tax ID only after you see how the employer is represented.
- Review the fiscal-year definition. The Hub assigns a case to the fiscal year in which USCIS first recorded an approval or denial. That may differ from the petition’s filing-receipt date.
- Separate “initial” and “continuing.” Initial counts cover petitions requesting new or new concurrent employment. Continuing counts cover other employment categories. Keep the two columns separate when comparing employers.
- Read the decision scope. The generated data include the first recorded approval or denial. Later appeal or revocation decisions are excluded, and petitions still pending when USCIS generates the data are not included.
- Inspect every location row. USCIS aggregates by fiscal year, two-digit NAICS, tax ID, state, city, and ZIP. One employer can therefore appear on several rows. Verify the tax ID and location before deciding that rows represent separate companies.
- Export and annotate. Record the search terms, fiscal years, filters, and download date. Note any missing or suspicious identifiers rather than silently correcting them.
USCIS cautions users about the limits of the identifiers. Its Data Accuracy section states: “We strive to ensure that the data in our electronic systems are accurate, but because we transfer data from paper forms into the electronic systems manually, data entry errors may occur.” Treat a missing city, an unusual name spelling, or an apparent duplicate as a reason to investigate, not as proof that the employer had no activity.
How to reconcile DOL and USCIS results
Do not expect the number of LCAs to equal the number of USCIS decisions. The LCA precedes the petition, an employer can file LCAs that are never used, and a single petition can involve facts that do not line up neatly with a disclosure row. Use the datasets as a timeline rather than as two totals to add together.
| Question | Best evidence | Careful wording |
|---|---|---|
| Has this entity filed labor-condition paperwork? | DOL LCA disclosure row and its determination field | “The employer appears in DOL LCA disclosures for [period].” |
| Has USCIS recorded an H-1B decision for the entity? | USCIS Hub approval or denial row | “USCIS recorded an initial/continuing approval or denial in fiscal year [year].” |
| Was a petition pending? | Neither public dataset, as described here | Do not infer pending volume from missing Hub rows. |
| Did a worker receive a visa or start employment? | Neither dataset alone | Ask the employer or worker for separate, lawful evidence; do not claim it from these files. |
For each employer, build a year-by-year worksheet with separate columns for DOL LCA activity, USCIS initial approvals, USCIS continuing approvals, and USCIS denials. Add the relevant occupation, wage, and worksite observations only when they help answer whether the employer’s past activity resembles the role you are considering.
How to compare potential sponsoring employers
Use the same fiscal years and definitions for every company. A comparison that uses one employer’s annual data and another’s partial-year data is not meaningful.
- Recent versus older activity: Identify whether records occur in several consecutive years or only in a distant period. State the years searched.
- Initial versus continuing approvals: A company with continuing approvals may be extending existing employment rather than hiring new H-1B workers. Do not combine the categories into a single “success” number.
- Approvals versus denials: Display counts by decision type and fiscal year. Because pending cases are omitted and only the first decision is included, do not present the ratio as an approval probability.
- DOL volume and status: Use LCA counts to understand filing activity and determination status, not to estimate approved visas.
- Role, location, and wage fit: Check whether the historical occupation, worksite, and wage information resemble the advertised position. A high volume in a different job family or state may not be relevant to you.
- Entity confidence: Mark whether the tax ID and address confirm the match. If names conflict, show the alternatives instead of silently pooling them.
A defensible comparison table might look like this:
Rank #3
| Employer/entity | Fiscal years checked | DOL LCA observation | USCIS initial | USCIS continuing | USCIS denials | Identity and role notes |
|---|---|---|---|---|---|---|
| Legal entity A | Same years for all employers | Record status and program, not “visa approvals” | Enter Hub count | Enter Hub count | Enter Hub count | Tax ID, location, occupation, and unresolved matches |
| Legal entity B | Same years for all employers | Record status and program, not “visa approvals” | Enter Hub count | Enter Hub count | Enter Hub count | Tax ID, location, occupation, and unresolved matches |
The table is a recording framework, not a claim that any particular employer has a stated count. Populate it from the same downloaded files and document the filters used.

In ordinary recruiting language, “sponsorship” can mean several different actions: agreeing to file an H-1B petition, transferring an existing H-1B, extending employment, or supporting later permanent-residence processing. The DOL and USCIS datasets do not identify an employer’s policy for your specific role.
Historical records can support a focused question—“Has this legal entity previously filed or received decisions?”—but not the questions that determine your application:
- Does the employer sponsor this occupation and level?
- Will it file for a new H-1B, accept a transfer, or support a change of status?
- Does its internal policy exclude candidates who need sponsorship now or later?
- Will the position’s location, salary, start date, and work authorization fit the filing?
Ask the recruiter or hiring manager these questions directly and request the answer in writing when the issue affects an offer. A public record should be corroboration for that conversation, not a substitute for it.
Requesting corroboration from an employer
DOL Fact Sheet #62F says: “H-1B employers must make the following materials available to the public within one working day of filing the Labor Condition Application (LCA) (Form ETA 9035 and/or ETA 9035E) with the Department of Labor:” The fact sheet was revised in August 2010, so use it as a description of the cited public-access requirement and check current DOL instructions for procedural details.

Rank #4
If a recruiter says the company sponsored a comparable role, ask for the relevant public-access file or for an explanation of the LCA’s employer, occupation, worksite, and wage fields. Keep the request narrow and do not ask for another employee’s private immigration documents. An employer’s willingness to explain a record is useful context, but it does not change what the public datasets record.

Calling an LCA an approved visa
Problem: An LCA row is described as a successful H-1B petition. Correction: Call it an LCA filing or OFLC determination, identify the program field, and look to USCIS for the later petition decision.
Adding every row under a similar name
Problem: Parent companies, subsidiaries, staffing firms, and clients are combined. Correction: Compare tax ID, address, legal name, and documented corporate relationships. Label an unresolved match.
Treating a partial year as a complete year
Problem: FY2026 Q3 is compared with full-year records as though all twelve months were present. Correction: State that the latest DOL release cited here covers October 1, 2025 through June 30, 2026, and compare it only with equivalent periods or clearly mark the difference.
Recommended Free Tools
Calculating an unexplained approval rate
Problem: Approvals are divided by all visible rows and presented as a chance of approval. Correction: If you calculate any descriptive ratio, define the numerator, denominator, fiscal-year basis, initial/continuing treatment, and exclusion of pending and later decisions. In most job searches, showing the separate counts is less misleading.
Assuming no Hub row means no filing
Problem: A missing employer is treated as proof that it never filed. Correction: Check name variants, location and tax-ID fields, the fiscal years searched, and whether a case could still have been pending when the data were generated.
Best Value
Using historical activity as a promise
Problem: A past approval is treated as a commitment to sponsor a new applicant. Correction: Use the records to identify a conversation target, then verify the current job’s sponsorship policy and petition strategy with the employer.
A repeatable worksheet for your job search
For every employer, save one dated worksheet containing:
- The exact legal name and every variant searched.
- Parent, subsidiary, staffing, and client relationships, with the evidence for each.
- DOL files used, including fiscal year or quarter and whether the row is H-1B, H-1B1, or E-3.
- DOL determination, occupation, wage, and worksite fields relevant to the role.
- USCIS Hub filters, fiscal years, tax ID, city, state, ZIP, NAICS code, and downloaded-file date.
- Separate USCIS initial approvals, continuing approvals, and denials.
- Uncertainty notes for missing identifiers, duplicate-looking rows, partial years, or unresolved entity matches.
- The employer’s direct answer about sponsorship for the specific position.
This record lets you update the search when a new fiscal-year file appears without losing the definitions used in the earlier comparison.
Bottom-line interpretation
Use DOL data to see whether an entity has labor-condition filing activity and USCIS data to see first recorded H-1B petition decisions. Search by legal identity, preserve the fiscal-year boundaries, separate initial from continuing cases, and inspect locations and tax IDs before counting anything. The result is evidence of past filing and adjudication patterns—not evidence of a current vacancy, a commitment to sponsor you, a pending case, a visa stamp, or guaranteed future approval.
