Evidence should support the particular knowledge claim and applicable process. A large document may not explain the employee’s capability.
Connect relevant material to actual work
Identify the person’s contribution and use. Do not imply authorship or advanced expertise solely because the employee received a copy.
Design documents, release notes, internal training material, project assignments and performance records that show the specialist's knowledge of the company's own system, together with a letter explaining why that knowledge is required at the U.S. site. Provide training records, permitted project summaries, internal role descriptions and other evidence that accurately explains the knowledge, deciding in advance with the applicant what needs special handling. The internal protocol with its version history and validation data, evidence of authorship, a written comparison with the published method, and a job description built around work that requires the protocol. Most resorts never wrote their pool procedures as a manual, and an L-1B petition built on an assertion that the specialist knows the system tends to draw a request for evidence. Use travel evidence only to place the employee at an assignment; pair it with dated work orders, technical reports, access logs, correspondence and supervisor explanations showing what was actually learned or performed. Do not confuse confidential information with specialized knowledge automatically: confidentiality may explain handling, but the record still must establish the category's substantive standard.
