IN THIS GUIDE · Resolve conditional job terms before relying on a TN start date
Start with the TN eligibility and application overview
Read every attachment to the offer
Hypothetical example: an offer identifies an engineering role, but a later assignment schedule is still being negotiated. Compare the actual proposed duties with the listed profession. Do not assume the title resolves the occupational fit or describe unconfirmed duties as settled work.
Identify the real employment arrangement
Name the employer and any agency or client involved. Explain remuneration, intended duration and ownership interests. A conditional arrangement needs an accurate explanation; a polished letter cannot supply a missing employer fact or remove the restriction on U.S. self-employment.
Match the credentials to the exact profession
Use the profession’s stated requirement rather than a generic assumption that any degree or experience is sufficient. Identify missing evaluations, licences or other relevant evidence for review. Canadian residence or permanent residence does not replace the citizenship requirement.
Coordinate the start with the applicable process
Review citizenship, current status and prior immigration history to identify the appropriate petition, visa where required, and admission process. A condition in the offer saying work begins immediately does not itself establish permission to perform that work.
Apply the temporary-work and credential boundaries
TN concerns qualifying temporary professional activity for Canadian or Mexican citizens. Providing services to a U.S. entity solely owned or controlled by the applicant falls outside the permitted arrangement; a foreign business interest alone is not a blanket disqualification. Degrees from institutions outside Canada, Mexico and the United States require a reliable foreign-credential evaluation. Any licence needed to practise the profession in the United States is a separate question from the listed TN qualification.
Let counsel map the description to a listed profession
The listing permits a baccalaureate or licenciatura degree, or a qualifying postsecondary diploma or certificate plus three years of experience. Land Surveyor includes a listed degree or a state, provincial or federal licence alternative. Federal regulation requires nurses and several other health occupations to present a certificate from an approved credentialing organization at admission, confirming education, licensure, English ability and, for nurses, passage of a recognized examination. Ask the institution, in the same request, whether it can confirm the programme's length, its award level and the year of conferral, since those are the facts a comparison against a profession's requirement usually turns on. A letter drafted by human resources for a general hire often omits the specific USMCA language, and an officer at a port of entry cannot infer what is not written. A written duty description with proportions lets counsel judge whether the position remains within the listed profession or has become something the listing does not cover. Being unable to seal a plat does not defeat a TN application, but an offer letter that promises sealed deliverables from someone who cannot lawfully produce them creates a conflict an officer can see. A Canadian citizen may present the fresh TN application at a port of entry or preclearance facility, or the U.S. employer may file Form I-129 with USCIS.
