IN THIS GUIDE · Explain what the employee actually knows about the company, not how long they have worked there
Name the knowledge instead of describing a reputation
The statutory standard concerns special knowledge of the company's product and its application in international markets, or an advanced level of knowledge of the company's processes and procedures. Write out the actual knowledge in plain language and connect it to supporting evidence. It does not need to be labelled unique or patented as a blanket requirement, but the file must explain why the applicable standard is met on these facts. The standard covers special knowledge of the organization’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.
Show how the knowledge was learned and where it was used
Gather training records, project history, and documentation of the applicant's actual responsibilities. Hypothetical example: a St. Catharines employee developed familiarity with an internal quality-control process across several projects and is now asked to introduce it at a U.S. facility. Identify the specific training and assignments that support that account, handling confidential material appropriately, rather than relying on a general statement of years of service.
Connect the knowledge directly to the proposed U.S. work
Describe the actual duties of the U.S. assignment and how the claimed knowledge will be applied there. If the person would work at a client's premises, disclose who directs and controls the work so any applicable offsite-placement rules can be reviewed. A client's request for this particular employee is not itself evidence of the specialized knowledge the category requires. For work principally at an unaffiliated employer’s site, L-1B is unavailable if that employer principally controls and supervises the worker, or if the arrangement is essentially labor for hire rather than a placement connected with the petitioner’s product or service requiring specialized knowledge.
Keep the underlying transfer conditions in view
The applicant generally needs one continuous year of qualifying employment abroad within the relevant preceding three years, and the U.S. and foreign entities need a qualifying relationship. Preserve the actual employment dates and ownership records. If the role is really primarily managerial or executive, that should be assessed as L-1A on the facts rather than folded into an L-1B filing as a fallback label. The qualifying foreign employment generally must be one continuous full-time year within the relevant preceding three years. Its capacity may be managerial, executive or specialized knowledge under the ordinary L rule; the proposed U.S. role has its own category test. Brief U.S. trips do not necessarily interrupt continuity, but U.S. days do not count toward the foreign year. The qualifying group must provide goods or services regularly, systematically and continuously in the United States and at least one other country throughout the relevant stay; registration alone is insufficient.
Identify a genuinely new U.S. operation
Less than one year of U.S. doing business triggers the new-office framework. A new-office L-1B case needs sufficient premises and financial ability to pay the worker and begin business; initial approval is limited to one year. The proposed work must still use qualifying specialized knowledge.
