Connect the material with the employee’s actual experience and contribution.
Explain authorship and substantive judgment
A shared slide deck may not show who developed the method or who understands difficult applications. Attribute work accurately and explain the trainer’s own judgment without claiming every team-created resource as personal authorship.
Build an evidence chain from the employee’s foreign experience to specific decisions embedded in the course. Preserve dated drafts, revision histories, technical notes, project assignments, performance records, and statements from knowledgeable supervisors explaining what the employee created, adapted, or approved. The training outline should flag modules requiring company-product knowledge or advanced understanding of internal processes, and it should distinguish the applicant’s contributions from shared material. Pair that record with proof of a qualifying related organization and one continuous qualifying year abroad within the previous three years. Avoid overclaiming exclusive authorship; an accurate explanation of substantive judgment is stronger than a slide deck bearing one person’s name. Also show that US instruction will use the identified specialized knowledge, remembering the general five-year L-1B maximum.
Hypothetical example: A resin-formulation specialist around Ferland-et-Boilleau helped refine an employer’s curing protocol. She supplies laboratory change logs, course annotations showing why certain mixtures require adjustment, and supervisor confirmation of her decisions, while crediting the design team for jointly produced graphics rather than presenting the entire manual as hers.
