Important Update(12/16/2025): We’ve recently added H-1B visa approval and denial history from USCIS(2017–2025) and H-1B visa petition locations to provide a more complete view of employment-based immigration. Previously, our data included only Labor Condition Applications (LCAs) certified by the U.S. Department of Labor.
For example, in fiscal year 2025, Zef Scientific filed 8 Form I-129 petitions for H-1B visas. Of these, 8 were approved and 0 were denied.

Zef Scientific, Inc. filed 10 labor condition applications (LCAs) for H-1B visas and 0 labor certifications (LCs) for green cards during fiscal year 2025. Zef Scientific was ranked number 7,398 among all visa sponsors. Additionally, all petitions were certified!

Before Zef Scientific can hire foreign workers, whether permanently or temporarily, it must submit labor certifications to the Department of Labor (DOL). These certifications confirm compliance with wage requirements for the specified job locations.The reports below summarize Labor Condition Applications (LCA) for H-1B visas and Labor Certifications (LC) for green cards filed by Zef Scientific. This data represents only the number of applications submitted and does not guarantee visa approvals or worker hires.

The LCA data includes applications for various purposes: new employment, continuation or changes to previously approved employment, new concurrent employment, changes in employer, and amended petitions. Typically, only LCAs for new employment require an H-1B visa cap if the employer is not cap-exempt.For example, Zef Scientific submitted 19 LCAs and LCs during fiscal year 2025. However, this figure does not necessarily reflect the number of foreign workers hired, as visa applications can be denied. Additionally, employees renewing or transferring H-1B visas or changing work locations may need to file new LCAs.

The DOL generally certifies more than three times the number of foreign worker requests compared to the H-1B visas issued by USCIS. Therefore, there is no direct correlation between the number of workers certified by the DOL and the H-1B visas issued by the United States Citizenship and Immigration Services (USCIS).

* Why are the numbers different? LCAs are a prerequisite to filing H-1B visa petitions, but not all certified LCAs lead to actual H-1B filings. Similarly, one LCA can support multiple visa petitions (e.g., for extensions, amendments, or changes in employer). Therefore, visa totals may differ significantly from LCA totals.
Moreover, employers sometimes use different names when submitting LCAs and H-1B visa petitions. This can cause discrepancies in our system. To get a complete and accurate picture, please use the search function to explore both LCA and visa data.
Total H-1B includes all types of visa petitions: new employment, continuation, change of employer, as well as other actions not listed in the table, such as concurrent filings and amendments.
