Review the actual change and preserve an accurate description of the engagement.
Do not infer new duties from a label
An administrative grade adjustment may differ from a new professional role. Assess material facts and the applicable process without treating every renamed position as a guaranteed new eligibility outcome.
Ask what changed on the effective date: only a human-resources band, or also the employer, core functions, worksite, compensation, ownership or duration. Preserve the old and new job descriptions plus the notice implementing the change. TN continues to depend on Canadian or Mexican citizenship, a USMCA-listed profession, that profession’s qualification and prearranged work free of US self-employment. Canadian permanent residence remains distinct from citizenship. The usual mistake is either refiling reflexively for a cosmetic edit or ignoring a substantive reassignment. Before new duties begin, decide whether updated admission is appropriate or whether the employer should use Form I-129; a Canadian can otherwise request TN classification at entry.
Hypothetical example: a food chemist from the Canton of Hatley is moved from “development grade A” to “product grade B,” yet continues testing formulations and interpreting laboratory results for the same employer. She obtains the grade-change memo, unchanged duty matrix and revised compensation letter. Those records may show an administrative promotion rather than a new occupation. If the employer later adds sales management and removes laboratory work, she should pause and reassess before performing that role. The calendar should follow the factual change, not the date someone edits her email signature.
