Lawrence Livermore National Security, LLC — filing by filing
All 44 stored filings on record for Lawrence Livermore National Security, LLC, each with its case number, decision date, occupation, offered wage and worksite. Every block states how many worker positions the filing covers and under which petition type, because those are not the same thing as people.

Latest decision Mar 12, 2026
Positions filed as NEW employment across the filings below — the closest honest read on new people being sponsored.
The same worker renewed. Shown separately and never added to the figure on its left, because adding them would count one person twice.
Filings certified by the Department of Labor. Certification is permission to file with USCIS, not a visa.

How to read a position count
Each filing below says how many worker positions it covers. That is a count of positions on one application, not a count of people, and the petition type is what tells the two apart. A new employment filing is a worker being sponsored into a role. A continued employment filing is the same person already doing the job, renewed for another term — so a company that renews the same ten employees every three years produces ten more positions each time without hiring anyone.
That is why nothing on this page adds the position column up. Across the filings shown, Lawrence Livermore National Security, LLC filed 11 new-employment and 13 continued-employment positions; those are two different measurements and their sum describes nobody.

Why some filings show a wage band instead of a salary
A filing covering a single position identifies one person. Those rows are published at reduced precision rather than dropped.
44 of the 44 filings shown cover exactly one worker position. A job title, a metro, an exact salary and an exact start date, published under an employer’s name, identify that individual to anyone who knows where they work — so those rows carry the $5,000 wage band instead of the salary, the month instead of the day, and no street address.
Filings covering two or more positions are shown in full: at least two workers share every attribute on the row by construction, which is precisely why they were filed together. Nothing is dropped either way — around nine in ten labor condition applications are single-position, and hiding them would misrepresent every employer’s activity by omission.
Each row above is one Labor Condition Application published by the US Department of Labor for Lawrence Livermore National Security, LLC as that name appears on the filing. A certified LCA is the employer’s wage and worksite commitment, and permission to petition USCIS — it is not a visa, not an approval, and not a job offer. Position counts are worker positions on the application, never a headcount. How these pages are built.
