IN THIS GUIDE · Explain the knowledge used to train a successor without assuming the original role continues unchanged
Start with the L-1B eligibility and application overview
Identify what is being handed over
Hypothetical example: an employee would explain an internal operating process, review the successor’s work and later provide general support. Identify the knowledge and actual responsibilities in each stage. Do not use the first handover period as a description of every possible later assignment.
Explain the existing knowledge
Identify special product knowledge and international application or advanced organizational process or procedure knowledge supported by experience. The knowledge need not universally be unique or secret. The fact that it can be taught to another person does not by itself decide whether the applicant meets the standard. Keep proof of knowledge separate from proof that a successor will need help. Training material may show a handover, but dated project work and access records are what connect the employee to the particular knowledge used in the proposed assignment.
Document acquired experience and proposed work
Use relevant training, project and responsibility records to explain what the applicant knows. Identify the actual U.S. duties and supervision. Prepare the qualifying company relationship and foreign-employment history separately rather than assuming the employer’s succession concern establishes eligibility.
Review the end of the handover
Describe what would happen when the successor can perform the work and what the applicant would do next. Have materially different duties assessed before relying on the initial plan. A company’s desire to retain the employee does not mean every later role is covered by the same analysis. Hypothetical example: At a grain-sorting automation company, an employee would teach a calibration method and later handle troubleshooting. Ask whether each phase uses the particular knowledge claimed, rather than whether retaining the worker is commercially convenient. Training logs, prior project files, system-access history, a detailed duty allocation, and the successor’s responsibilities help test the point. Later troubleshooting that is routine technician work calls for its own analysis before it is folded into the handover narrative.
Explain the complete U.S. role and qualifying employment
The electrician needs one continuous year of employment abroad with the company, within the last three years, in a managerial, executive or specialized-knowledge capacity, and the Canadian and U.S. entities must be qualifying organizations that are both doing business. USCIS asks whether the knowledge is different from that generally found in the industry and whether it is held by only some of the company's employees. US days are not foreign-year days, but travel does not automatically break continuity. Specialized knowledge should be described so a reader can understand both its depth and its relationship to the organization’s international work. L-1B preparation should explain the company-specific knowledge actually held, without assuming that using an outside vendor makes specialized knowledge impossible or automatic.
