IN THIS GUIDE · Make the claimed company knowledge understandable and connect it to the assignment
Identify the knowledge rather than a reputation
The standard covers special knowledge of company products, services, research, equipment, techniques, management or other interests and their application in international markets, or advanced knowledge or expertise in company processes and procedures. Describe the relevant knowledge in plain language and connect it to evidence. It need not be labelled unique or proprietary as a universal requirement; the file needs to explain why it meets the applicable standard. The general foreign-employment rule requires one continuous full-time year within the relevant three-year period in managerial, executive or specialized-knowledge capacity. Brief U.S. trips need not break continuity, but U.S. days do not count toward the foreign year. The U.S. assignment must independently meet the requested classification.
Show how the employee acquired and used it
Gather training history, project examples and records of relevant responsibilities. Hypothetical example: a Calgary employee learned an internal implementation process through successive projects and is asked to introduce it to a U.S. team. Identify the training and work that support that account, protecting confidential material appropriately. Years of service alone do not explain the knowledge being claimed. A qualifying parent, branch, subsidiary or affiliate relationship must accompany regular, systematic and continuous business in the United States and at least one other country throughout the L stay. An entity’s registration alone is not doing business.
Connect the knowledge to the proposed work
Describe the U.S. assignment, expected activities and the way the claimed knowledge will be used. If the person will work at a client site, disclose who controls the work and the placement arrangement for the applicable offsite rules to be assessed. A customer request or a technical title cannot substitute for a clear explanation of the actual duties. If the person will be principally stationed at an unaffiliated worksite, L-1B is unavailable where the unaffiliated employer principally controls and supervises the worker, or the placement is essentially labor for hire rather than tied to the petitioner’s product or service requiring its specialized knowledge. Location alone does not decide the issue.
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 the employment dates, ownership records and operating evidence. If the role is primarily managerial or executive, compare L-1A on the actual facts rather than treating L-1B as a fallback label for an unresolved management case. Where the U.S. organization has been doing business for less than a year, the L-1B new-office requirements include sufficient premises and financial ability to pay the employee and commence business, alongside qualifying specialized knowledge. Initial new-office approval is limited to a maximum of one year.
