L-1B Position Evidence
L-1B Job Duties and the U.S. Specialized Knowledge Position
Why proving that an employee possesses specialized knowledge is only half of the L-1B analysis and how the U.S. duties must actually require it.
Direct answer
What the governing framework requires
An L-1B petitioner must establish both that the beneficiary possesses specialized knowledge and that the proposed U.S. services involve that knowledge. Federal regulations require a detailed description of the services to be performed. Generic occupational duties do not explain why special or advanced company knowledge is required.
01 · Two Part Showing
The employee and the position must both be addressed
A beneficiary can possess sophisticated company knowledge but still have an insufficient case if the proposed U.S. job does not require that knowledge.
The petition should connect each major U.S. responsibility with the specialized knowledge needed to perform it.
02 · Specific Duties
Ordinary occupational descriptions are usually not enough
Duties such as analyze requirements, manage projects, support customers, or develop software may describe workers across an entire industry.
The filing should explain the company-specific systems, products, methods, or advanced processes involved.
03 · Knowledge Mapping
Identify which knowledge is used in each important duty
A duty-to-knowledge matrix can help make the relationship between the beneficiary's expertise and U.S. responsibilities understandable.
04 · Foreign Role
The U.S. job does not have to be identical to the foreign job
The regulation expressly permits different U.S. work so long as the foreign qualifying employment and proposed U.S. classification satisfy the L requirements.
05 · General Skills
Industry skill should be separated from qualifying organizational knowledge
A beneficiary may use both ordinary professional skills and specialized company knowledge.
The petition should identify what portion of the position actually depends on the specialized knowledge.
