IN THIS GUIDE · Make the claimed company knowledge understandable and connect it to the U.S. assignment
Identify the knowledge rather than a reputation
The standard covers special knowledge of the company’s products, services, research, equipment, techniques, management or other interests and their application in international markets, or advanced knowledge or expertise in its processes and procedures. Describe the relevant knowledge in plain language and connect it to concrete evidence. It need not be labelled unique or proprietary as a universal requirement; the file needs to explain why the applicant's knowledge meets the applicable standard.
Show how the employee acquired and used it
Gather training history, project records and documentation of relevant responsibilities. Hypothetical example: an Ottawa employee learned an internal deployment process across several product releases and is now asked to introduce it to a new U.S. team. Identify the training and work history that support that account, while protecting confidential technical material appropriately. Years of service alone do not explain what knowledge is actually being claimed.
Connect the knowledge to the proposed work
Describe the U.S. assignment, its expected activities, and how the claimed knowledge will actually be used there. If the person would work at a client or partner site, disclose who controls the work and the placement arrangement so any applicable offsite rules can be assessed. A client request or an impressive title cannot substitute for a clear account of the actual duties. At a primarily unaffiliated worksite, L-1B is unavailable if that employer principally controls and supervises the worker, or the arrangement is essentially labour for hire rather than a placement connected with the petitioning employer’s specialized-knowledge product or service.
Keep the transfer conditions visible
Generally, one continuous year of qualifying employment abroad within the relevant preceding three-year period and a qualifying relationship between the organizations must be established. Preserve employment dates, ownership records and operating evidence. If the proposed role is actually managerial or executive, compare L-1A on the real facts rather than treating L-1B as a fallback label for an unresolved management case. The group must continue regular business in the United States and abroad. Qualifying foreign service may be managerial, executive or specialized knowledge, while U.S. work must meet L-1B; U.S. days do not count toward the foreign year, although brief visits do not automatically break continuity. A U.S. organization doing business less than one year is a new office: requisite knowledge, sufficient premises and financial ability to pay and commence business must be shown, with initial approval at most one year. The qualifying foreign employment must be full-time.
