Immigration Law Firms Specializing in H-1B Employer Sponsorship
The H-1B visa program is the primary pathway for U.S. employers to hire foreign professionals in specialty occupations. Behind nearly every successful H-1B petition is an immigration law firm managing Labor Condition Applications (LCAs), USCIS filings, and compliance obligations on behalf of the sponsoring employer.
Market Landscape
The U.S. business immigration market is dominated by a handful of high-volume firms. According to FY2025 LCA data, Fragomen, Del Rey, Bernsen & Loewy leads with nearly 60,000 annual LCA filings, followed by Berry Appleman & Leiden (BAL) at 33,000+ and Ogletree Deakins at 20,000+. These firms primarily serve Fortune 500 employers in technology, consulting, and financial services.
However, thousands of boutique and mid-size immigration firms serve the long tail of employers—startups, mid-market companies, universities, and healthcare systems—that collectively file hundreds of thousands of H-1B petitions each year.
What Employer-Side H-1B Counsel Does
- LCA Preparation & Filing
- Before any H-1B petition reaches USCIS, the employer must file a Labor Condition Application with the Department of Labor certifying prevailing wage compliance. Experienced firms manage this end-to-end.
- Petition Strategy
- With the H-1B lottery selecting roughly 25-30% of registrants, firms advise on timing, cap-exempt categories, and alternative visa pathways (O-1, L-1, TN) when appropriate.
- RFE Response & Compliance
- Requests for Evidence (RFEs) have risen in recent years. Employer-side counsel drafts responses, manages Public Access Files, and handles DOL audits.
- Green Card Sponsorship
- Many H-1B engagements evolve into PERM labor certification and I-140 processing for permanent residency, requiring long-term counsel relationships.
