The invitation alone does not establish the standard. Explain the special or advanced organizational knowledge used in the training and the actual assignment.
Assess what the training depends on
Identify the methods, experience and problem-solving that the applicant brings. Teaching generic material is not automatically specialized knowledge, and sharing knowledge does not automatically remove its qualifying character. The employment period and organizational conditions remain separate. Avoid describing the employee as the only person able to teach unless that factual claim is supported and relevant.
A first review should produce a short eligibility map that marks facts already proved, facts needing a primary record, and facts that cannot be solved by a job title. Confirm the qualifying organizations, the continuous qualifying foreign year in the preceding three years, and the particular knowledge before relying on a project need. The five-year L-1B ceiling must be calculated independently from the duration the business would prefer. Hypothetical example: a designer of underwater cameras transfers an employee who knows its calibration sequence but also performs routine repairs.
The decision is to resolve any missing eligibility fact before presenting the role as settled.
