Corporate documents proving the parent-subsidiary relationship, Owen's employment history and a detailed specialized-knowledge statement with training and authorship evidence, plus the client service agreement and a placement letter showing the subsidiary keeps control of his work.
Two files: one proves the knowledge, the other proves who is in charge
Think of the petition as two evidentiary files. The first proves eligibility: share registers or organizational charts showing the Canadian company owns the U.S. subsidiary, evidence both are doing business, an employment letter and payroll confirming Owen's continuous year in Canada, and the specialized-knowledge package — a narrative statement, the internal training curriculum, his completion certificates, procedure documents bearing his authorship, and service records showing escalations.
The second file addresses the offsite placement: the service contract with the client identifying the simulators and the maintenance scope, a placement letter naming Owen's supervisor at the subsidiary, describing reporting frequency and stating that the client will not direct his work or assign him other tasks, and a description of the equipment he will maintain. If the client will provide a workspace or badge access, say so and explain that this does not transfer control. Keep the itinerary consistent with the eighteen-month plan.
Hypothetical example: Ibrahim maintains a Canadian company's proprietary acoustic-monitoring system for rail bridges and will assist its U.S. affiliate. His file should cross-reference each claim of specialized knowledge to a training record, a controlled procedure, an authorship record or a service escalation.
The client contract settles whether the affiliate retains control over his work at the site. Put corporate ownership documents first, then the qualifying-employment evidence, then the knowledge materials, so an officer can follow the logic without searching through attachments. A generic technical résumé cannot establish the company's proprietary content.
