That fact alone does not decide the case. Assess the employee’s actual qualifying knowledge and assignment.
Explain the different responsibilities
A general vendor may perform a different service. Describe the real distinction without asserting that L-1B universally requires secret knowledge or an irreplaceable employee.
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. The requirement is one continuous year of qualifying employment with the qualifying organization outside the United States in the three years before the petition, and a qualifying parent, branch, subsidiary or affiliate abroad may satisfy it. L-1B specialized knowledge means special knowledge of the organization's products, services, research, equipment, techniques, management or other interests and their application in international markets, or an advanced level of knowledge of the organization's processes and procedures. Mark later summaries honestly, explain missing records, and show why the applicant's knowledge concerns this organization's interests or reaches an advanced level in its processes rather than reflecting ordinary occupational ability.
