Start with the TN eligibility and application overview
Assess the present engagement
Canadian or Mexican citizenship, a listed USMCA profession and its particular qualifications remain central. Explain actual duties, remuneration and duration. Do not assume an unchanged job title means every relevant term is unchanged. Start with a duty-by-duty comparison, not a title comparison. A useful first review separates professional functions from sales, supervision or general operational tasks and identifies which listed profession is said to cover the core work. The decision is whether the written offer can accurately describe the professional assignment as it will be performed. A résumé can explain experience, but the employer's current duty description is the record that settles what work is being offered.
Use history without substituting it for current facts
Review the employer and disclose every ownership stake. U.S. self-employment is not permitted; the prohibition is not limited to sole or controlling ownership of the U.S. enterprise receiving the services. A Canadian citizen may request TN admission at a U.S. port of entry without a TN visa stamp, or the U.S. employer may file Form I-129. The current facts and route determine the evidence required. Hypothetical example: a Sidney statistician is offered a ten-month role by a US retail-data company to build demand forecasts and train its analytics team. The offer uses the title Product Lead, while the signed project schedule lists statistical modelling, model validation and written forecasts as the work. She holds a small share in a separate Canadian consultancy but has no ownership or control of the US company. The choice is to present the fixed project and the actual statistical duties, with degree evidence and the employer's letter, rather than describe an open-ended leadership job. If she were to own or control the American enterprise receiving the services, TN would not be available for that arrangement; the share in the unrelated Canadian business does not answer that question.
Temporary work and credential review
For an applicant revisiting an earlier TN file, reassess temporary intent and credentials against the current offer. A foreign degree may need a reliable evaluation. Any licence required to practise is distinct from the profession’s TN entry credential. A foreign business interest is not itself disqualifying, but every ownership stake should be disclosed and the U.S. engagement must not be self-employment. Process choice follows the facts. A Canadian applicant may request TN classification when seeking admission with the supporting record; in other circumstances, the employer can pursue an I-129 petition through USCIS before the work starts. A Mexican applicant generally needs a TN visa before travel. Neither path cures missing qualification evidence, an inaccurate duty letter or an impermissible self-employment arrangement. Confirm the proposed start only after the chosen route, the evidence and any professional licence have been checked together.
