No universal impossibility-to-train requirement applies.
Explain the actual standard
Provide qualifying knowledge evidence rather than an exaggerated exclusivity claim. Confirm current charges separately from business training and staffing costs.
Identify which company records and explanatory work the specific claim actually needs, and keep that preparation and legal review separate from government filing fees, any optional processing service, and family-related applications. The government charges for an L-1B petition are fixed by the USCIS fee schedule (G-1055): the Form I-129 fee, the fraud prevention and detection fee and any surcharge that applies to the petitioner, with premium processing as an optional addition. Company staff time, translation and professional services may be separate considerations; obtain clear scope rather than assuming one package includes everything. Confirm whether a quoted review covers technical material, since specialized documents often sit outside a standard scope and reappear as a separate invoice.
