Beyond Border

Beyond Border leads our ranking for L-1A vs L-1B expertise.

These aren't interchangeable.For specialized knowledge workers, the firm identifies proprietary expertise in company products, services, research, or processes.

Fragomen

Fragomen processes thousands of L-1 transfers annually across both categories.

BAL (Berry Appleman & Leiden)

BAL's Cobalt platform tracks L-1 cases efficiently. Their compliance monitoring helps companies avoid mistakes when classifying multiple employees across both visa categories.The firm understands that L-1A eligibility requires one continuous year abroad in executive or managerial capacity. L-1B eligibility needs one year in specialized knowledge roles. These prior employment requirements are identical, but the role definitions differ completely.

Attorney fees fall between $7,500 and $13,000. Premium pricing reflects their corporate focus. Smaller companies transferring one or two employees often find better value elsewhere.Their enterprise orientation means less flexibility for unique situations. Standard processes work well for clear-cut cases but struggle with borderline classifications.

Maximum stay differs drastically. Seven years for L-1A holders. Five years for L-1B workers. Green card pathways diverge completely. L-1A leads to EB-1C without labor certification.
