Not by itself. Explain the actual special or advanced organizational knowledge and its use in the proposed role under the relevant standard.
Separate general expertise from the claim
Identify the employer’s product or processes and the applicant’s relevant experience. A public rule may provide context without proving the claimed knowledge. The other L conditions remain separate requirements.
A commercial relationship may explain exposure to a product without establishing employment by a qualifying organization. Avoid an unsupported claim that no U.S. worker could perform the role. A regulated licence is general skill available in the labour market. General industry competence, however impressive, is not the standard, and neither is seniority. Where the answer is yes after a few weeks of ordinary onboarding, the knowledge is industry skill. L-1B requires special or advanced knowledge of the company's own products or procedures, shown by the company's documentation and the specialist's history with those specific products.
The L-1B standard does not impose a universal requirement that knowledge be secret, proprietary or unique. L-1B is reserved for a person with special knowledge of the petitioning organisation's own product, service, research, equipment, techniques, management or other interests and their application in international markets, or with an advanced level of knowledge of its processes and procedures.
