The actual professional work needs to be established. Naming a listed profession does not resolve an undefined job or waive its prescribed qualifications.
Clarify what the person will actually deliver
Identify the genuine responsibilities being negotiated. Do not promise to change the facts later merely to fit an application description. A useful assessment distinguishes agreed duties from possibilities.
If the diploma is in hotel or restaurant management, the experience requirement is a documentation exercise: letters from each former employer stating the dates, the position and the responsibilities held, signed by someone with authority to confirm them. The practical fix costs nothing: ask the employer for a letter that states the position is an engineering role, describes engineering duties in concrete terms, and notes the internal administrative title separately if payroll requires it. The supporting package must still establish Canadian or Mexican citizenship, a prearranged position within a listed USMCA profession, and the exact qualification required for that occupation; money cannot cure a category mismatch. Bring the offer, the proposed duties and the available registrar records to counsel together, so the assessment is about the specific listing rather than a general assumption that a transcript is always the required proof.
