The evidence must accurately identify your own contribution and knowledge.
Distinguish shared projects and individual work
Common company background may be relevant, but another person’s achievements should not be attributed to you. Explain what you actually did and how it supports the proposed US duties.
Separate reusable company evidence from personal proof. Corporate records may establish the qualifying relationship and active operations, but the worker needs an individual chronology of foreign employment, training, system access, projects, authored materials and problem-solving. Payroll and travel evidence should confirm a continuous qualifying year abroad during the relevant three years. For specialized knowledge, label shared project outputs accurately and obtain supervisor explanations that identify this applicant’s contribution. Never sign a declaration implying authorship of a colleague’s examples. The US assignment plan should connect the documented company knowledge to specific tasks and retain petitioner control over any offsite placement. Note the one-year initial rule for a new office and the five-year L-1B limit.
Hypothetical example: an embedded-systems integrator at a Canton of Hatley apiary-monitoring sensor maker worked on the same release as another engineer. She gathers her access logs, dated firmware reviews, training record and messages showing how she adapted the company’s hive-alert protocol. The colleague’s circuit diagrams remain attributed to him. Her manager can explain the shared release while isolating her integration decisions and the US troubleshooting she will perform. Honest attribution supplies a clearer specialized-knowledge narrative than a copied portfolio that could unravel under questioning.
