A promotion may add duties that need closer review. The title alone does not establish that every task fits the original listing.
An accommodation concerns access and participation; it does not replace the TN evidence of citizenship, listed profession, qualifications, prearranged professional employment and temporary entry. TN classification requires Canadian or Mexican citizenship, not Canadian permanent residence alone, plus prearranged work in a profession listed under USMCA and satisfaction of that profession’s particular qualification rule. The omission a reviewer notices is narrower than most applicants expect: the letter never names the listed profession it relies on, so the duties float free of any category. The listed profession and the credentials it prescribes come second, since an occupation absent from the USMCA professional list closes the route however firm the funding becomes. The employer letter should identify the work, pay arrangement, location, and anticipated period so that the professional assignment can be assessed against the listed occupation rather than against a broad job title.
