Do not assume that an internal business unit is a separate legal entity. Identify the actual structure and have the qualifying relationship assessed using the relevant records.
Use legal structure and actual duties together
A division may explain the scope of the applicant’s work without establishing the corporate relationship by itself. The applicant still needs to meet the relevant employment and managerial or executive requirements. There is a workable order for this.
First, name the legal entity that employs the applicant abroad and the legal entity that would employ or receive the applicant in the United States, relying on registrations rather than internal labels. Second, ask what relationship exists between those two entities, whether it is one of the qualifying kinds such as parent, branch, subsidiary or affiliate, and whether it continues to exist now rather than at some earlier point. Third, test the year: one continuous year of full-time employment abroad with a qualifying organisation within the three years preceding the filing or admission.
Fourth, describe managerial or executive capacity through decisions actually taken. Hypothetical example: a clinical-supplies wholesaler presents a division that reports to the U.S. business on an internal chart, while every share in the operating company is held by an unrelated family holding and no qualifying relationship exists at all.
Each step can invalidate the ones after it, so answering them out of order wastes the preparation spent on the later ones. Where an answer is unavailable rather than negative, say so and note who could supply it. An unanswered question tracked by name stays manageable; the same question left blank tends to reappear as an assumption nobody remembers making.
