Yes, if she can document five years of experience as a management consultant or five years in the field of specialty related to the engagement. The evidence must be a statement or credential attesting to that experience, backed by records.
The experience route works only when the years are provable and relevant
Hypothetical example: the consultant left university after two years, spent six years as a supply-chain coordinator for an ag-input retailer, then four years consulting. For an inventory-planning engagement, either route may fit: five years in the specialty, or five years as a consultant if the consulting years reach five. Choose the stronger and prove it. Employment letters from the retailer stating dates and responsibilities, and consulting engagements documented by contracts and invoices, become the file. A professional designation in supply-chain management would strengthen the specialty argument. The letter from the distributor should state which line is relied on rather than leaving the officer to infer it. She must be a Canadian or Mexican citizen; permanent residence does not qualify. The distributor must be the entity engaging her, she must not own a controlling interest in it, and the work must be consulting rather than a disguised staff position.
Hypothetical example: a dietitian is hired by a U.S. rehabilitation clinic and has the academic credential for the listed profession, but the destination state requires a separate licence before clinical practice. A first review produces an eligibility map covering citizenship, profession, duties, credential, and the hiring entity; the licensing record settles whether her proposed start date is realistic. The clinic must choose either a presentation at a port of entry or an I-129 petition. In either route, TN cannot be used to run an independent practice the dietitian owns.
