IN THIS GUIDE · Explain the essential function and the work others perform
Start with the L-1A eligibility and application overview
Define the function concretely
Hypothetical example: an applicant is assigned responsibility for an organization-wide commercial function. Explain its scope and significance in the actual business, not merely a broad title such as strategy. Identify the applicant’s real decisions. A function manager must act at a senior level over an essential function and primarily manage it. First-line supervision of nonprofessional workers alone is insufficient.
Separate managing from performing
Show who performs the function’s operational work and the applicant’s senior-level role. A person carrying out an essential task is not automatically managing the function. There is no universal headcount or fixed task-percentage shortcut.
Establish the qualifying transfer facts
Generally document one continuous qualifying foreign year within the relevant preceding three years, a qualifying parent, branch, subsidiary or affiliate relationship and ongoing qualifying business in the United States and abroad. The importance of the function does not replace those requirements.
Assess actual support in a launch case
New-office L-1A needs sufficient premises, a qualifying foreign managerial or executive year and support for the U.S. role within one year of approval. Initial approval is limited to one year. Identify future resources as planned rather than already operating. A new office means less than one year of U.S. doing business. An owner or major stockholder must also show temporary U.S. services and a subsequent foreign assignment.
Establish the qualifying foreign year and active organizations
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.
Managerial capacity is defined by decisions, not by headcount
For a manager of people, the deciding records are the organizational chart with names rather than boxes, each subordinate’s position description and start date, and payroll or contractor invoices proving those people exist and are paid. Parent and subsidiary, branch, or affiliates under common ownership and control are the qualifying forms, and long collaboration is not one of them. A manager directs the organization, a department or a function, supervises professional or supervisory staff or manages an essential function, and holds discretion over day-to-day operations. Managerial capacity can rest on directing an essential function rather than on supervising a headcount, and in a matrixed structure that is frequently the more accurate description of what the position actually does. The review should end with a role map showing decisions reserved to the transferee, the personnel or function that carry out routine work, and the evidence that the US and foreign entities have the required relationship. The petition should describe a role that manages other managers or an essential function of the enterprise, sets budgets and hiring, and has authority over policy. The question is not whether the operation is busy; it is whether the transferee will direct an essential function or supervise professionals and managers.
