Not by itself. Explain the actual expertise under the special or advanced knowledge standard and how it supports the US work. A company may route difficult questions to an employee for several reasons; the routing practice alone does not establish the classification.
Show the reasoning behind a solution
Identify the method, company context and decision the applicant contributed. Connect that example to training and experience. Avoid equating workload, popularity or availability with specialized knowledge, and keep the qualifying foreign employment and corporate evidence separate.
Document why the employee is the escalation contact rather than merely noting how often colleagues call. Describe the company-specific product, process, or procedure involved; the unusual depth or advancement of the knowledge; how it was gained; and why the proposed US duties need it. General occupational expertise, seniority, or strong performance is insufficient. Confirm separately a single uninterrupted foreign-employment year within the three years before filing or admission, plus an eligible link—parent, branch, subsidiary, or affiliate—between the U.S. and foreign organizations, with the foreign organization doing business and the U.S. organization either doing business or meeting the initial new-office requirements. Where a new office is involved, the first approval cannot exceed one year, and the record must support the intended specialized-knowledge role. L-1B time is generally capped at five years. The common error is substituting incident volume for an explanation of proprietary reasoning.
Hypothetical example: A Sherbrooke fermentation-sensor developer sends its applications specialist the hardest calibration questions. For a transfer to its US subsidiary, the company should select examples showing how she applies internal algorithms and production history unavailable in standard manuals, while identifying what ordinary engineers can resolve. Her foreign-year records and corporate link remain essential; a crowded support queue alone does not demonstrate special or advanced company knowledge.
