No. The offer must involve prearranged work in a profession on the USMCA list, and the applicant must meet that profession's specific qualification and citizenship requirements; a title alone does not establish either.
Read the duty list against the profession's own criteria
Compare the documented tasks to the applicable profession's requirements point by point, and identify the record supporting each qualification claimed. If the employer later changes the duties, reassess the revised facts rather than continuing to rely on the original offer. Some proposed roles will not fit any listed profession, and the file should reflect that outcome rather than reshape the description to fit a category.
The appendix entry for registered nurses accepts a state or provincial licence, or a licenciatura degree, so a nurse licensed in a Canadian province already holds the qualification the category asks for. Where someone holds both Canadian and Mexican citizenship, or has prior United States records under a third nationality, ask counsel which route fits the facts. TN requires citizenship of Canada or Mexico, prearranged professional employment, temporary entry, and the credentials the listing specifies; an internal code speaks to none of these.
