No universal all-products requirement applies. Explain the actual qualifying knowledge relevant to the proposed work and have the full L-1B requirements assessed.
Focus on relevance rather than catalogue size
A broad list may establish exposure without explaining depth or application. Identify what the applicant actually knows and how the assignment uses it. A narrow focus still needs sufficient evidence of special or advanced knowledge.
The knowledge must be the company's, not the industry's: a skilled welder, a fluent programmer or a senior planner has general expertise unless the file shows that what they know is particular to how this group builds, sells or services something. For each claim of specialized knowledge, ask which document inside the company would prove it, and whether that document could have been obtained from a supplier, a trade association or a textbook. The company's regime, with its specific schedules, cultures, brine concentrations and the reasons behind each choice, is knowledge of the company's processes and procedures. L-1B specialized knowledge must concern the company’s offerings or advanced knowledge of its procedures; ordinary skill with a public standard is insufficient, although public material does not automatically defeat the claim. L-1B requires a continuous qualifying year abroad during the three years before the relevant filing or admission, plus a parent, branch, subsidiary, or affiliate relationship between operating businesses.
