Potentially. Supervising colleagues does not itself prevent L-1B, but the evidence must establish specialised knowledge and a U.S. role involving that knowledge. A lead title alone proves neither L-1B nor L-1A qualification.
Start with actual duties
Describe the employee’s personal technical work, decisions and supervisory responsibilities. Determine whether the intended classification fits the role and supporting evidence rather than reshaping the duties to fit a preferred label. The foreign qualifying capacity may differ from the U.S.
role, but the required employment history and corporate relationship must still be established. Verify the intended classification against the evidence available rather than against the preferred outcome. Supervising colleagues does not prevent this classification, and a lead title establishes neither it nor the managerial alternative, so the title is simply not evidence.
Describe the employee personal technical work, the decisions they make and the supervisory responsibilities they hold, then ask which classification the record actually supports. Reshaping duties to fit a chosen label produces a file contradicting the operating reality and usually contradicting itself. The foreign qualifying capacity may differ from the proposed U.S.
role, and the required employment history and the corporate relationship must still be established in their own right. Ask what evidence would exist if the opposite classification were correct, and check whether it does.
