Distinguish the topic and the person
Do not imply that appearing in an article proves every capability or that all readers share the same practical expertise. Connect the individual’s experience to the proposed US work.
Internal documents created in the ordinary course: validation and commissioning reports, procedure revision histories, training matrices, project files and correspondence identifying the employee as the source of the knowledge. Evidence that the knowledge belongs to the employer rather than the trade: internal documentation of the proprietary system, records of the training or development work through which the knowledge was acquired, and a description of how few people in the organization hold it. Build a dated record of the pilot’s true progression: design notes, test versions, results, unresolved defects, training materials, and examples of the employee’s contribution. Supplement the paper with training records, project assignments, technical evaluations, and comparisons showing special or advanced company knowledge; authorship by itself is not the standard. Start with evidence that existed before the petition: training records, restricted technical material, version histories, project assignments, and letters explaining why comparable employees cannot simply take over. Many confidential documents are not evidence of specialized knowledge, and many strong L-1B cases can be explained without giving a reviewer unrestricted access to commercially sensitive material.
