Ask which documents need review and whether that work is included. Separate immigration preparation from the company’s training-development expenses.
Avoid paying for irrelevant volume
Agree on the purpose of each evidence category and any necessary translation. More course material does not necessarily make the knowledge claim stronger. Confirm government charges separately and clarify the scope if the role changes.
Someone has to identify the proprietary process precisely, retrieve training and validation records that may be on a shared drive nobody has curated, and describe technical material in language a non-specialist reviewer can follow. The larger cost in an L-1B is professional time spent turning a control-system change log and internal design notes into an explanation an adjudicator without engineering training can follow, which is where most specialized-knowledge petitions succeed or fail. Legal fees rise with the complexity of the knowledge narrative, so an employer saves money by preparing the internal document index, training records and organization charts before counsel starts. Check the published fee schedule for current amounts and any optional faster-adjudication charge, then set beside it a realistic estimate of the hours needed to produce contemporaneous documents, translations and a truthful account of staffing depth.
