Start with the TN eligibility and application overview
Match the actual professional qualification
TN concerns qualifying temporary professional activity for Canadian or Mexican citizens in listed USMCA professions. Apply the particular profession’s requirements; experience is not a universal substitute for education. Degrees from institutions outside Canada, Mexico and the United States require a reliable foreign-credential evaluation.
Separate qualification, practice and engagement
Any US licence needed to practise is separate from the listed TN qualification. Identify actual duties, employer, remuneration and duration. Sole or controlling ownership of the US enterprise receiving services raises prohibited self-employment; a foreign business interest alone is not a blanket bar. A Canadian citizen may apply for TN classification at a port of entry without obtaining a TN visa stamp, or a US employer may file Form I-129; a Mexican citizen generally needs a TN visa.
Sequence the contract structure before the experience file
Hypothetical example: an Orford graphic designer with a qualifying Canadian post-secondary diploma issued after at least two years of study and seven years of freelance work is offered a twelve-month engagement by a Colorado outdoor-apparel brand. She invoices her clients through a Québec company she owns outright, and the brand proposes to pay that company. The order of decisions matters. First, settle who the TN employer is: a foreign employer may send its employee to render professional services to a U.S. entity, but the support letter must then come from her Québec company as employer and describe the U.S. engagement, or the brand must engage her directly. Owning the Québec company is a foreign business interest and is not a bar; she must disclose any ownership in the U.S. brand, while sole or controlling ownership—or other facts showing U.S. self-employment in substance—would bar TN. Second, because the Graphic Designer listing accepts a post-secondary diploma only with three years of experience, gather dated contracts, invoices and client letters that add up to that period; a portfolio shows skill but not duration. Third, as a Canadian citizen she may present the file at the port of entry without a visa. That order avoids rebuilding the experience file after the employer changes. Hypothetical example: a Canadian urban planner is offered an eight-month zoning-analysis assignment by a U.S. planning partnership. The draft letter promises only “planning support,” while her degree is in geography and the partnership expects her to sign municipal submissions. She must decide whether the proposed duties and education actually fit the Urban Planner listing before choosing the filing path. The degree, transcript, employer letter, work plan, and the jurisdiction’s signature rules settle separate questions. If the job instead requires a credential she does not hold, a polished title or a fee paid through her own business cannot repair the mismatch. Once the role is supportable, the choice is between a direct Canadian request at entry and an employer-filed petition; the evidence must describe the same employment relationship either way.
