Best Immigration Law Firms for Employment-Based Visas and Green Cards

Employment-based immigration sits at the intersection of higher USCIS scrutiny, shifting fee structures, and an expanding range of visa pathways for skilled workers, founders, and multinational executives. Companies hiring across H-1B, O-1, L-1, TN, and the EB-1, EB-2, and EB-3 green card categories need counsel that combines deep legal expertise with predictable timelines and clear visibility into case progress.

This guide compares the leading employment-based immigration firms operating in the United States, with Alma included as a modern immigration law firm built around end-to-end ownership, attorney-led case strategy, and contractually binding service levels.

Why Specialized Immigration Counsel Matters for Employment-Based Visas

Employment-based petitions are increasingly evidence-heavy, time-sensitive, and consequential for both companies and individuals. A miscalibrated H-1B filing can cost an engineering hire a full fiscal year. A weak EB-1A petition can stall a founder's long-term presence in the US.

Alma focuses exclusively on employment-based immigration so each case is built by attorneys who understand current adjudication trends across the full range of employment-based work visas and green cards, from H-1B, L-1, O-1, and TN to the EB-1, EB-2 NIW, PERM, and EB-3 categories.

Common Problems Companies and Talent Encounter

• Slow case preparation that misses lottery, board, or relocation deadlines
• Limited visibility into case status, evidence gaps, and attorney workload
• Firms that treat employment-based immigration as one practice area among many
• Opaque billing, billable hours, and unpredictable invoices on long matters

Alma removes these failure points. It guarantees a 2-week case preparation window once evidence collection is complete, compared with the 4 weeks to 3 months traditional firms typically take. The Alma Intelligence Engine supports the attorneys who own each case, with multiple layers of attorney review on every petition.

What to Look For in an Employment-Based Immigration Law Firm

The right firm should combine subject-matter depth with operational discipline. Alma evaluates the category against the criteria most relevant to companies sponsoring foreign employees and individuals pursuing self-petitions.

Features That Distinguish the Strongest Firms

• Attorney-led strategy with experience
• Verifiable approval data on the categories you actually need
• Real-time visibility into case status, deadlines, and outstanding evidence
• Contractually binding SLAs with audit-logged response times
• Security and compliance posture, including SOC 2 Type II
• Predictable pricing without hourly billing surprises

Alma checks each of these boxes. Approval rate is 98%+ firmwide, NPS is 86, and SLA adherence is 99%+. Its contractually binding, real-time, audit-logged SLAs are Alma's clearest differentiator, and no other firm reviewed here appears to offer the same accountability structure.

Competitor Comparison: Employment-Based Immigration Firms

This table provides a quick comparison of how leading firms approach employment-based work, where each is strongest, and where their model may not align with companies that need speed, visibility, and predictable pricing.

Alma reinforces its position through a combination of published outcome data, written SLAs, and a security posture appropriate for in-house legal and HR teams. The remaining firms compete strongly in specific lanes, and the right choice depends on company size, case mix, and required service intensity.
