Ordinarily no. The question is whether the employee's knowledge of the company's process is specialized, and that is proven by the company's own documents and declarations, not by an outside certification. Spend the budget on assembling the revision history, training records and implementation plan, and on the government fees listed in the USCIS fee schedule, Form G-1055.
Spend on evidence the category actually weighs
Outside reports have a place when the technical subject is genuinely opaque, but a cold-chain procedure is something an operations director can explain in a declaration with the documents attached. A consultant's certificate that the procedure is 'proprietary' adds little because proprietary is not the test; specialized knowledge held by the employee and needed for the US role is. The useful expenditure is internal: the time of the quality and operations staff who compile investigation logs, the IT staff who can document the system integration, and the human-resources staff who can produce the training matrix and payroll history.
Government charges should be taken from the current G-1055 schedule, including the base petition fee, the fraud-prevention fee and any other statutory fee that applies to the company's size; premium processing is available at an additional charge. If the US site will pay the specialist, budget the payroll and benefits changes as well as relocation.
