L-1B Visa
Intracompany transferee visa for employees with specialized knowledge of the company's products, services, processes, or operations.
About This Visa
The L-1B is a nonimmigrant visa for employees with specialized knowledge being transferred from a qualifying foreign office to a U.S. office of the same multinational organization. Specialized knowledge means proprietary or advanced knowledge of the petitioner's products, services, research, equipment, techniques, management, or other interests—not knowledge that is commonly held in the industry.
The transferee must have worked for the qualifying foreign entity in a managerial, executive, or specialized-knowledge capacity for at least one continuous year within the three years before the U.S. petition. The U.S. and foreign entities must share a qualifying relationship—parent, subsidiary, branch, or affiliate.
L-1B status is granted for up to 5 years total. New-office petitions are initially limited to 1 year. The L-1B is dual-intent and L-2 spouses receive work authorization. Specialized-knowledge cases are heavily scrutinized; clear differentiation between the employee's knowledge and what is common in the field is essential.
L-1B petitions are among the most RFE-prone employment-based filings. Specialized knowledge must be carefully distinguished from ordinary expertise—the strongest petitions tell a concrete, fact-specific story about why this person and this knowledge are not interchangeable with the U.S. labor market.
Who Qualifies for an L-1B?
Specialized knowledge is the hinge of every L-1B petition. USCIS expects evidence that the employee's knowledge is either proprietary to the petitioner or significantly more advanced than what is generally found in the relevant industry.
One continuous year of employment with the qualifying foreign entity in the three years before the U.S. petition, in a managerial, executive, or specialized-knowledge role
Specialized knowledge—either proprietary knowledge of the petitioner's products, processes, or operations, or advanced knowledge significantly above what is common in the industry
Qualifying relationship between the U.S. and foreign entities (parent, subsidiary, branch, or affiliate)
Both U.S. and foreign entities must be doing business as employers throughout the L-1B period

Specialized Knowledge Documentation
We build the record showing the employee's knowledge is proprietary or significantly advanced—training records, project history, internal certifications, comparisons to the broader labor market, and a clear articulation of why this employee cannot be readily replaced from outside the organization.
Qualifying Relationship
We document the relationship between the U.S. and foreign entities with corporate charters, ownership records, organizational charts, and tax filings—the same evidentiary backbone as L-1A petitions.
File Form I-129
The U.S. employer files Form I-129 with USCIS, including the L Supplement and supporting evidence. Premium processing is available for $2,965 with a 15-business-day response. Blanket L petitioners follow a streamlined consular process for qualifying employees.
Visa & Entry or Change of Status
After approval, the employee applies for the L-1 visa at a U.S. Consulate, or—if already in the U.S. in valid status—the I-129 can request change of status. L-2 dependents follow with their own applications.
