IN THIS GUIDE · Separate a Saint-Augustin-de-Desmaures fabricator's welding know-how from the company process that actually qualifies for L-1B
Start with the L-1B eligibility and application overview
Draw the line between trade skill and company process
Write two columns. In the first, list what any certified welder in the region could do. In the second, list what exists only because of this company: the calibration sequence, the inspection tolerances it set for its own product line, the internal documentation system, the training it built around them. L-1B lives in the second column. If the second column is empty after an honest attempt, the transfer is a skilled-worker transfer, not a specialized-knowledge one.
Show the knowledge was gained here and used here
Collect the dated procedure revisions with the technician's name on them, the internal training sessions he delivered, and the projects on which the procedure was applied. Payroll records proving the continuous year with the Québec entity go alongside, because the qualifying employment and the specialized knowledge must both be established and they are proved by different documents.
Tie the knowledge to the U.S. assignment in concrete terms
Describe what the affiliate's shop will do with him: install the fixtures, run the first inspection cycles, train its own inspectors, and hand over the documentation. Give the assignment an end state and a duration. If any of that work will happen at a customer's site, disclose it, because offsite placement cannot be labour supplied to another employer and the Québec group must keep controlling his work.
Keep the corporate and time limits visible
The qualifying relationship between the Québec fabricator and the U.S. affiliate must be shown through ownership records, and both must be operating. L-1B status runs to a maximum of five years in total. If the assignment later grows into running the U.S. shop, that is an L-1A question on new facts, not an automatic upgrade. Before relying on an organization chart, decide whether it answers ownership, control, or operations; a chart can show a name but not settle any of them. Match the chart to share registers or equivalent ownership records, then collect a current business record from each entity that makes the assigned role credible. This sequence matters because a technically strong knowledge claim cannot cure an unproven corporate link, and a dormant U.S. entity may not support the claimed assignment. If a reorganization occurs before filing, stop and map the post-reorganization relationship rather than attach records from the old structure and hope the reviewer connects them.
