Use records that identify the applicant’s own decisions and responsibilities after training, together with an accurate description of the training itself.

A completion certificate establishes its stated training achievement; it may not establish advanced knowledge of the employer’s implementation. Consider dated change records, internal instructions, problem analyses and corroborating explanations from people who know the work. Explain the applicant’s contribution where a document has several authors. Review confidentiality before submitting technical material, and do not alter ownership or authorship to strengthen the narrative.
The first review should produce an exhibit index with original document, date, author, proposition proved and translation or explanation needed. Compare names, duties, dates and amounts across the file, because a small inconsistency is easier to correct from a primary record before filing.
Hypothetical example: A composite-sail inspection analyst finds that an important record uses a different date and name from the summary. The applicant must decide whether the original document or an accurate explanation resolves the difference before filing.
The worker needs twelve uninterrupted qualifying months with the related organization during the 36 months before filing, and L-1B has a five-year aggregate cap. Sequence the next step only after the controlling record is available. A rushed filing often fails because an undefined commercial fact, mismatched document or unauthorized activity remains hidden until review. Keep the decision, the record and the resulting action together in the file.
