Not by itself. The employment history abroad and the knowledge claim are assessed separately. Seniority, headcount, and budget authority say little about knowledge of the organization's products, services, or advanced procedures. A strong showing describes what this person knows and applies, not how many people reported to them.
Describe the knowledge, not the rank
Ask the applicant to describe a concrete problem that drew on special knowledge of the organisation’s products or services, or advanced knowledge of its processes. Record what they knew, how they acquired it and how the proposed US role uses it. Other colleagues may share the knowledge; a limited headcount is not a universal condition.
Explain the substantive knowledge rather than treating prior rank or supervisory authority as proof. Ask the applicant to describe a concrete problem that drew on special knowledge of the organisation's products or services, or advanced knowledge of its processes, then record what they knew, how they acquired it, and how the proposed United States role uses it. That account is the showing.
Seniority, headcount, and budget authority say little about it, and the employment history abroad is assessed separately from the knowledge claim. Other colleagues may share the knowledge, and a limited headcount is not a universal condition, so there is no need to claim exclusivity. Explain the substantive knowledge rather than treating prior rank as proof of it.
