Common Mistakes

1. Not Demonstrating Knowledge Is Truly "Specialized"

USCIS requires evidence that the knowledge is not commonly held in the industry. Describe proprietary systems, unique processes, or company-specific expertise that distinguishes this employee.

2. Generic Job Descriptions

Vague descriptions of duties without connection to specialized knowledge trigger RFEs. Tie every duty to the specific knowledge the employee possesses.

3. No Comparison to U.S. Workers

Explain why the knowledge cannot be obtained by hiring a U.S. worker or through training.

4. Insufficient Training Documentation

Provide training records, certifications, and internal documents showing how the employee gained the specialized knowledge.

Frequently Asked Questions

What qualifies as "specialized knowledge" for the L-1B?

Specialized knowledge means advanced or special knowledge of the company's products, services, technology, or procedures that is not commonly available in the U.S. labor market. Examples include expertise in proprietary software systems, unique manufacturing processes, or company-specific management methodologies gained through significant experience with the organization.

Can L-1B holders get a green card?

Yes, but the path is different from L-1A holders. L-1B holders pursue green cards through the EB-2 or EB-3 categories, which typically require PERM labor certification and have longer processing times. L-1B holders cannot use the EB-1C multinational manager pathway. Some L-1B holders qualify for the EB-2 NIW as a self-petition alternative.

Can L-1B holders get a green card?

What is the maximum stay on an L-1B visa?

The L-1B maximum stay is 5 years. The initial petition is approved for up to 3 years (1 year for new offices), with extensions in 2-year increments up to the 5-year maximum. After reaching the maximum, the employee must remain outside the U.S. for 1 full year before being eligible for a new L-1B.

What is the maximum stay on an L-1B visa?

How does L-1B processing time compare to H-1B?

L-1B standard processing takes 3-6 months, similar to H-1B (3-8 months). Both offer premium processing for $2,805 ($2,965 after March 1, 2026) with a 15 business day guarantee. The key advantage of L-1B is no lottery or annual cap - petitions can be filed year-round, while H-1B is limited to the annual registration period.
