IN THIS GUIDE · Whether the knowledge belongs to the employer rather than the trade, and who controls the work at a client's site
Start with the L-1B eligibility and application overview
Rare is not the same as specialised
Hypothetical example: Rachid commissions hybrid solar-and-generator controllers for an installer near Saint-Joachim-de-Shefford that serves off-grid properties on back concessions, and only two people in the company can tune the controller's load-shedding logic. Scarcity inside the firm is useful evidence and it is not the test. The question is whether what Rachid knows is knowledge of the employer's own product, process or procedure, or general competence with equipment sold to anyone. If the controller is the company's own design, with firmware and commissioning sequences it wrote, the answer is straightforward. If the controller is a manufacturer's unit and Rachid attended the manufacturer's course, the petition is describing a well-trained technician and needs a different foundation, or a different category.
Documenting knowledge that lives in someone's head
The hardest L-1B files are the ones where the knowledge is genuine and has never been written down. Small companies teach by apprenticeship, and there is no manual because the person who would write it is the person being transferred. Evidence still exists, but it has to be collected rather than composed: commissioning reports in the employee's hand, configuration files with revision histories, internal training records showing who taught whom, customer-specific parameter sets, and correspondence in which colleagues escalate problems to this person. A document written last month purely for the petition is worth less than a three-year-old field report, and an officer can tell the difference. Where a manual has to be created, say when and why it was created rather than presenting it as a long-standing record.
Offsite placement has its own rule
When an L-1B employee will be stationed mainly at a company other than the petitioner, the statute imposes conditions that the petition must address directly. The employee must not be controlled and supervised principally by the unaffiliated company, and the placement must not be essentially an arrangement to provide labour for hire rather than work requiring the employer's specialised knowledge. Answering that means producing the services agreement and pointing at the clauses that keep direction with the petitioner: who assigns tasks, who reviews the work, who can remove the employee, who owns the deliverable, how the customer is billed. A time-and-materials contract that bills hours to the client's supervisor is describing the arrangement the rule was written to exclude.
