H-1B filings (Department of Labor)

Before filing an H-1B petition, an employer must get a Labor Condition Application (LCA) certified by the Department of Labor. These are this company's LCAs, by fiscal year.

H-1B approvals (USCIS)

After DOL certifies an LCA, the employer files the H-1B petition with U.S. Citizenship and Immigration Services (USCIS), which approves or denies it. New petitions and extensions or transfers are counted separately.

USCIS also has records for this company in FY2009–FY2019: 85 new H-1B petitions approved. Show FY2009 onward

Salaries

Offered salary is the yearly pay an employer states on a certified, full-time H-1B filing — the bottom of the range when it gives one. Hourly, weekly and monthly pay is converted to a yearly figure; amounts under $15,000 or over $1,000,000 a year are left out. The typical range is the middle half: a quarter of filings offered less, and a quarter more.

What the filings were for

What its certified H-1B filings since FY2023 were for, as marked on each LCA. One filing can cover several workers, so these count worker positions.

Green card sponsorship (PERM)

Most employer-sponsored green cards start with a PERM labor certification, filed with the Department of Labor. These are this company's, by fiscal year.

FY2026 is in progress: data runs through June 30, 2026.

Across all its green card filings since FY2020, whatever the outcome. DOL's newer PERM form doesn't include citizenship or education, so those two lists cover filings made on the older one.

E-Verify

On the E-Verify list

PRELUDE SYSTEMS INC. appears on USCIS's list of E-Verify employers dated December 31, 2018, in a state it files from.

Why it matters: employers must be enrolled in E-Verify to employ F-1 students on the STEM OPT extension (8 CFR 214.2(f)(10)(ii)(C)).

This list is from December 31, 2018, and it's the only one USCIS has published. It shows who was enrolled on that date: a company that enrolled later isn't on it, so not being on the list tells you nothing.

Other things to know

H-1B dependent

Yes

On at least half of its certified filings in FY2023–FY2025 that answered the question, the company said it is H-1B dependent. A dependent employer has a large share of H-1B workers on staff and makes extra promises about recruiting and not displacing U.S. workers.

How we work this out

The employer answered Yes to H1B_DEPENDENT on at least half of the certified LCAs where it answered the question, in FY2023-FY2025. false means it answered and Yes was under half; NULL means no certified case answered the question (E-3 and H-1B1 filings answer N/A). The floor is there because a single Yes among thousands of No answers is a tick in the wrong box: it would badge 979 employers that said Yes once, one of them on 1 filing of 2,760; the 473 that answered only once or twice still are. A dependent employer is not a worse employer: the answer is a statutory test on the share of H-1B workers on staff, not a finding.

Willful violator

No

The company's answers on its filings in FY2020–FY2025 don't show a repeated yes. Employers state on each filing whether DOL has found them to be a willful violator in the five years before; this is the company's own answer, not a DOL record.

How we work this out

The employer answered Yes to WILLFUL_VIOLATOR on at least two LCAs in FY2020-FY2025, certified or not, in at least two fiscal years, and in at least one of those years Yes was half or more of what it answered. The floor is there because a single Yes among thousands of No answers is a tick in the wrong box: 505 employers answer Yes exactly once and never twice, and the two employers with the most Yes answers say it on one filing in two thousand. false means the employer answered and did not meet that bar; NULL means it never answered. THIS IS THE FILER'S OWN ATTESTATION ON THE LCA, NOT A DOL FINDING. The authoritative source is the DOL published debarment list, which this project does not yet mirror - it is a follow-up catalog entry - so nothing here has been checked against it.

Cap-exempt

No sign

Nothing in its name or industry code suggests a college or university. That doesn't make it subject to the cap: nonprofit research organizations and affiliated hospitals can be exempt too, and we can't detect them.

How we work this out

INFERRED, not a determination. true when an FY2023+ LCA carries a NAICS code beginning 6112 or 6113 (junior colleges, colleges and universities) or a raw spelling of the employer's name contains the word UNIVERSITY or COLLEGE. Never false: the column is NULL when neither signal is present, because the absence of a signal is not evidence that an employer is cap-subject. Non-profit research organisations and affiliated hospitals are cap-exempt and both tests miss them. Only USCIS decides cap exemption, petition by petition.
