IN THIS GUIDE · Explain the factual basis of a manager’s support letter
Start with the L-1A eligibility and application overview
Identify what the writer actually knows
Hypothetical example: a new supervisor describes work performed before joining the company. Explain whether the account relies on genuine records or other knowledgeable staff. Do not present later assumptions as firsthand observations.
Support authority with operating evidence
Identify actual decisions, discretion and the people performing operational work. A letter calling the applicant an executive does not establish those facts. Explain personal execution duties honestly and have the actual role assessed.
Use appropriate corporate and employment records
The writer may describe duties without being the right source for ownership or legal-employer facts. Provide relevant records separately and reconcile dates and names. A shared brand alone does not establish a qualifying relationship.
Clarify uncertainty rather than filling it with praise
Identify missing evidence and the genuine basis of any explanation. Do not invent historical responsibilities or backdate statements. Review the actual proposed U.S. duties and applicable process with the full record.
Establish the qualifying foreign year and active organizations
The foreign employment generally must include one continuous full-time qualifying year within the relevant preceding three-year period, assessed on the individual facts. U.S. days do not count toward that foreign year; a trip should not automatically be treated as breaking continuity. The qualifying organization must do business in the United States and at least one other country during the relevant period, through regular, systematic and continuous provision of goods or services rather than registration alone. For an ordinary L petition, the qualifying foreign work may be managerial, executive or specialized knowledge; the U.S. duties must meet the requested classification. New-office L-1A specifically requires managerial or executive foreign employment.
Show a receiving organization that can support an executive
L-1 begins with a qualifying relationship between the sending and receiving entities as parent, branch, subsidiary or affiliate, and family sentiment does not create one. A manager under L-1A supervises other supervisors or professionals, or manages an essential function at a senior level, and has authority over hiring and firing. L-1A status is available for a maximum of seven years, and where the American entity has been doing business for less than one year the first approval is limited to one year with evidence of secured premises and the capacity to support the role. A function-manager theory does not require inventing direct reports, but a person primarily doing the function’s operational work is not established as its manager by a strategic title. If the transferee owns or is a major stockholder, assess the additional temporary-service and subsequent foreign-assignment evidence. Supervising a crew of non-professional workers is not by itself managerial; the rule looks for control over supervisory, professional or managerial staff, or management of an essential function. An executive-capacity claim rests on discretion over a major function and on supervision that flows through subordinate managers. In a machining business the managerial question deserves care, since operations managers in smaller shops often spend much of their week doing the work rather than directing an organization that performs it.
