Green card sponsorship (PERM)

|---|---|---|---|---|
| FY2021 | 1 | 0 | 0 | 1 |
| FY2022 | 140 | 122 | 2 | 16 |
| FY2023 | 62 | 45 | 2 | 15 |

E-Verify
On the E-Verify list
CONTROLLED CONTAMINATION SERVICES is listed in a state it files from.
| Name as listed | Location | Workforce size | Federal contractor |
|---|---|---|---|
| Controlled Contamination Services | San Diego, CA 92121 | 500 to 999 | No |
| Controlled Contamination Services, LLC | San Diego, CA 92121 | 100 to 499 | No |
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)).
USCIS has published only this one list, dated December 31, 2018. A company that enrolled later isn't on it, so not being on the list tells you nothing.
How we match companies to the list
The employer's name key appears in the USCIS E-Verify participating-employers list with a state the employer files in. That list is one snapshot, enrolled as of 2018-12-31, so false means only "not on the 2018 list" - not that the employer does not use E-Verify today, and not that it did not enrol the following week. The list carries no FEIN and no case number, so the match is by normalised name and state alone.
Other things to know
- H-1B dependent
- Not stated
None of its certified filings in FY2023–FY2025 answered the question. Dependent employers have a large share of H-1B staff and make 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
- Not stated
It didn't answer this question on its filings in FY2020–FY2025. Each filing asks whether DOL found it 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. It may still be exempt: nonprofit research groups and affiliated hospitals can be, 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.
