No. Tenure can explain how knowledge was gained, but the evidence must show qualifying specialized knowledge and the other L-1B requirements.
Turn experience into an evidentiary account
Begin by identifying the organization-specific subject matter: a protected process, unusual configuration method, manufacturing sequence, implementation technique, research program, or internally developed service model. Explain what the applicant knows, how the knowledge was acquired, how widely it is held inside the enterprise, and why the U.S. role needs it.
The comparison should be accurate. It is risky to call knowledge rare when a standard manual or broad training program shows otherwise; it is also unnecessary to prove that no other employee could ever do the job. Describe the level and relevance of the knowledge with concrete examples from projects or responsibilities.
Then establish the qualifying overseas employment period and the corporate relationship separately. An employee can be highly capable yet fail one of those independent elements. The proposed U.S.
duties must genuinely draw on the claimed knowledge, rather than using L-1B as a shortcut for a conventional vacancy. Keep the explanation accessible to a reader outside the technical team by defining internal terms and connecting them to the company’s products or services. Invite the applicant’s overseas supervisor to identify a specific before-and-after example of the knowledge being acquired and applied.
Such examples should be truthful and tied to records. They are more revealing than a long list of buzzwords, and they help distinguish organizational knowledge from an employee’s general professional talent.
