No. The applicant’s qualification and the proposed professional activity are separate elements. Canadian or Mexican citizenship, the exact listed profession’s credentials and qualifying prearranged work must all be considered. The role cannot be classified from the diploma alone.
Show what requires engineering judgment
Have the manager describe a representative decision from beginning to end: the question, technical method, conclusion and responsibility for the result. That account can help distinguish engineering analysis from purchasing coordination. It is evidence for a case-specific assessment, not a formula guaranteeing classification.
USMCA Appendix 2 lists the professions eligible for TN and states the minimum qualification for each. Each listed profession sets out its own credential alternatives, and they differ considerably from one another. Some occupations accept a post-secondary diploma plus three years of experience; others accept only a baccalaureate; a few accept a licence in place of a degree. The review starts by finding the exact Appendix 2 line, reading its qualification column, and asking which record in the applicant's file satisfies it. An engineer who spends most of the week supervising hourly staff is describing a supervisory job, and no rewording turns that into a listed engineering role. The decisive record is usually the official degree, licence, or required experience evidence, not a recruiter’s description.
