Start with the L-1B eligibility and application overview
Show both instruction and operational delivery
Prepare an assignment schedule identifying what the employee teaches, what they perform and the company knowledge each task uses. L-1B may rest on special knowledge of company products or other interests and international application, or advanced knowledge of its processes and procedures. No universal uniqueness or proprietary requirement applies. A syllabus alone cannot describe an assignment that also includes substantial delivery work.
Anchor the schedule in qualifying employment
Document the corporate relationship and continuous full-time foreign employment year within the relevant three years. Keep US travel days out of the foreign-year total; qualifying brief visits do not themselves interrupt continuity. The qualifying group must maintain regular, systematic and continuous business in the US and another country. A customer-funded course does not establish the employer relationship or this operating history.
Explain the customer’s authority during each part of the assignment
Where the employee works primarily at an unaffiliated employer’s site, the placement is barred if that employer principally controls and supervises the worker. The separate labour-for-hire restriction requires distinguishing staff supply from work connected with the petitioner’s product or service needing specialized knowledge specific to that petitioner. Describe supervision during both teaching and delivery; calling the whole visit training does not change the real arrangement.
Check resources before moving delivery ahead of training
If the US organization has been doing business for less than one year, show new-office premises and financial ability to pay the employee and commence operations. Initial new-office approval cannot exceed one year. Identify the equipment and support actually available for the revised sequence. Keep anticipated delivery capacity separate from existing resources, and reassess changed duties instead of assuming the original teaching plan covers them.
Industry certification is general skill, not specialized knowledge
Where an L-1B employee is placed at a site not controlled by the petitioner, the placement must not be essentially labour for hire, and the petitioner must retain control over the employee's work, including day-to-day direction and the discretion over the work performed. The existence of documentation does not automatically defeat a claim, but a statement that the applicant has read the manuals is not enough to establish special or advanced knowledge. Begin with concrete examples: internal procedures the employee has applied, training records, projects that required the knowledge, and an explanation of why the US assignment calls for it. L-1B does not universally require unique, secret or proprietary knowledge or a general U.S. recruitment test. If the honest answer is that the system is assembled from standard components and operated conventionally, the specialized-knowledge claim is weak and it is better to know that early than to discover it in a response to a request for evidence. 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 record should distinguish ordinary familiarity with a product from the employee's documented application of the company's particular methods. The decision is whether the evidence shows advanced or uncommon organizational knowledge rather than strong general industry skill.
Distinguish related processes from interchangeable knowledge
A first review should make an individual knowledge matrix showing what the employee learned, where it was applied, why it matters to the related U.S. business, and what documents corroborate it. The file should identify which knowledge supports L-1B without falsely claiming that common tools are proprietary or that all experienced users are interchangeable. Processes change while someone is away, and a file claiming current advanced knowledge of a procedure introduced during the absence will not survive a question about when and how the person learned it.
