Attendance is evidence of training, not a complete determination of qualifying knowledge.
Explain what the applicant can apply
Describe the process and the applicant’s actual capability, using reliable examples. Knowledge need not be unique or proprietary, but the file should establish special organizational knowledge or advanced process knowledge relevant to the U.S. role. The remaining transfer conditions still apply.
Ask what exists: revision histories naming the employee, internal design or commissioning documents, training material they authored, project files showing the sequence of work, purchase records showing equipment was adapted rather than bought as standard, and any registered intellectual property. L-1B also requires one continuous qualifying year abroad within the applicable preceding three, active entities linked through a qualifying parent, branch, subsidiary, or affiliate relationship, and U.S. duties that actually use the asserted knowledge. A useful first review creates a comparison between ordinary industry competence and the organization’s internal methods, identifies witnesses who can verify training or project history, and fixes the project dates the U.S. assignment must meet.
