Training and immigration preparation serve different purposes. Paying for a course does not guarantee the employee will meet the knowledge standard or receive approval.
Identify the evidence already available
Ask which actual work records and company explanations are needed, and distinguish their preparation cost from future business training. Confirm current government and professional fees for the intended case. Avoid buying generic certificates simply to enlarge the file when they do not explain the petitioner-specific knowledge used in the assignment.
Government filing charges per the USCIS fee schedule, optional premium processing, counsel's fees for the eligibility review and petition, staff time to document the quality system, and L-2 applications for the family. Where L-1B differs is in the professional effort: assembling proprietary documentation, drafting a technical narrative that a non-specialist adjudicator can follow, and responding to a request for evidence, which is frequent in this category. The substantial costs are internal: producing and organizing the proprietary documentation that proves specialized knowledge, reviewing the customer contract, and counsel's time responding to a request for evidence, which this classification attracts more often than others.
