First identify which facts need evidence and which records explain them. A large operational archive may add volume without clarifying the applicant’s knowledge.
Define a relevant document scope
Ask what selection, explanation and translation work is needed, apart from professional review and official charges. Preparation should serve the actual knowledge claim rather than an assumed requirement to submit every routine record.
Beyond fees, the cost that matters is preparing evidence: assembling and translating manuals and logs, drafting position descriptions and obtaining a management letter, and professional fees if counsel is used. Government charges should be confirmed on the current Form G-1055 schedule, while translations, document retrieval and adviser services belong in separate budget lines. If the applicant attended a course, gather the agenda, attendance record, instructor, internal materials, and proof of who paid rather than renaming a sales invoice. When the beneficiary will be stationed primarily at an unaffiliated client site, the client must not principally control and supervise the beneficiary, and the placement must relate to a product or service requiring petitioner-specific specialized knowledge rather than labour for hire. Ask counsel whether a request for evidence is covered and whether the quote includes a later extension, since specialized-knowledge cases attract questions.
