It does not decide eligibility by itself. Examine the role’s actual powers, the employees or function managed and whether the applicant primarily performs qualifying management duties.
Explain what the restriction changes
A restriction may limit a particular decision without eliminating the entire management role. Conversely, a managerial title does not cure a job that has become mainly operational because vacancies remain unfilled.
Identify the decisions the applicant would control, their authority over staff or an essential function, and who performs the day-to-day operating work. The route through is function management: the person manages an essential function of the organisation, operates at a senior level within it, and exercises discretion over its day-to-day operations. The role must be primarily managerial or executive; listing countries or colleagues without explaining their work does not establish that capacity. L-1A requires one continuous year of qualifying employment abroad within the three years before the petition with a parent, branch, subsidiary, or affiliate of the U.S. petitioner. Show who will perform routine operational work while the transferee directs the function or organization. Supervising a crew of operators is first-line supervision and usually does not qualify; directing supervisors, budgets and hiring may.
A first-line supervisor is not a manager unless the employees supervised are professionals.
