Start with the L-1B eligibility and application overview
Explain the knowledge behind the teaching
The relevant standard is special knowledge of company products and international application, or advanced knowledge of company processes and procedures. It does not universally require unique or proprietary knowledge. Identify the substance the employee understands and applies, including how training decisions depend on company experience; a teaching title or a shortage of trainers is not the whole test. Training files, technical change records, internal manuals and examples of decisions can show why the knowledge matters to the proposed work. A first review should ask which record proves the employee learned and applied the company-specific method, not merely attended a course. Hypothetical example: A dairy-robot sanitation protocol specialist can explain a company sequencing method but has only a generic certificate. The employer must decide whether operational records can substantiate advanced knowledge or whether the proposed US role needs revision.
Connect the proposed instruction to a qualifying transfer
Establish qualifying organizations and regular, systematic, continuous business in the US and another country, plus the continuous qualifying foreign year within the relevant three years. US days do not count toward that year but trips do not automatically break continuity. Primarily offsite work with an unaffiliated employer requires examination of actual control and labour-for-hire restrictions. A US new office doing business for less than a year needs sufficient premises and financial ability to pay and commence business, with initial approval limited to one year. Where the work is at a customer location, agreements should identify who assigns tasks, supervises performance and controls the day-to-day activity. The company should sequence the corporate-relationship evidence, foreign-employment proof and role materials before treating a customer need as the reason for eligibility. An urgent installation date cannot replace proof of the qualifying transfer or the specialized-knowledge role. The filing sequence should also identify the US worksite, the entity directing the employee and the records available before the requested start date. Missing control evidence cannot be supplied by a generic customer letter.
Ask whose product or process the knowledge concerns
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. Internal training records, project histories, the employee’s role in developing a procedure, documents they authored or validated, and a candid estimate of how long an experienced replacement would take to reach the same position all speak to the claim. The knowledge must be the company's, not the industry's: a skilled welder, a fluent programmer or a senior planner has general expertise unless the file shows that what they know is particular to how this group builds, sells or services something. The work must remain controlled and supervised by the petitioning employer rather than by the site owner, and the arrangement must not amount to providing labour for hire. If the employee’s knowledge is genuinely of those things, the claim concerns the petitioner’s own equipment, techniques or procedures. Compare the claimed knowledge with what a skilled worker in the industry would ordinarily know, using the company’s own process or product evidence where possible. The U.S. position description should focus on configuring, commissioning and troubleshooting the proprietary system, training dealer technicians on it and feeding field data back into the Canadian design team. The risk is a file that describes a valuable employee in general terms but never explains why this assignment calls for that employee's knowledge.
