A truthful employer letter, contract or statement of work can be used; the substance matters more than the label. A defined scope and end date help show genuine Management Consultant duties, while direct employment by the U.S. entity requires careful analysis rather than being categorically disallowed.
The instrument signals the relationship
Hypothetical example: a Hampton applicant is given a standard offer letter with a salary, benefits, a start date and no end date. Nothing in it is untrue, and everything about its form says permanent employment. A consulting agreement or statement of work covering the same arrangement puts the scope, the phases, the deliverables and the completion date at the front, which is what the Management Consultant analysis focuses on.
If the company will employ her directly, the file should explain why the temporary position is genuinely consultative and include a scope document appended to the letter with a stated engagement period. Alongside that, the qualification evidence has to be there: the degree, or the dated letters and contracts proving five years as a management consultant or in a field of specialty related to the consulting agreement. Both halves are required, and a strong scope document does not rescue thin experience evidence.
