Describe genuine involvement with the relevant organizational processes or products and how that knowledge will be used.
Use concrete evidence
A broad statement that managers know everything does not establish the particular special or advanced knowledge.
With the organization's own records: protocol authorship and revision history, validation and deviation reports, training materials, and a signed statement quantifying how many employees hold comparable knowledge and how long a replacement would take to train. Internal records that existed before the transfer was contemplated: training curricula, controlled procedure documents, engineering change notes, deployment logs, and evidence of how few people in the organization hold the same knowledge. Ask which examples establish the material facts, and coordinate the employer's technical staff and legal reviewer before submission so the evidence neither overexposes confidential information nor becomes too generic to support the claim. Use evidence created during ordinary work wherever possible: mentor statements, shift assignments, maintenance tickets, annotated diagrams, training attendance, quality records, and messages resolving particular production failures. Use corporate ownership records and operating evidence for the organization link; use contracts, payroll, tax documents, leave records, and supervisor letters for the foreign employment; use training records, controlled manuals, work samples, and a detailed US assignment for the knowledge claim.
