IN THIS GUIDE · Read the actual professional engagement behind a consulting contract
Start with the TN eligibility and application overview
Match the deliverables to a listed profession
TN is for qualifying temporary professional activity by Canadian or Mexican citizens in listed USMCA professions. Each profession has its own prescribed credentials and permitted alternatives; experience is not a universal degree substitute. Hypothetical example: a contract groups professional analysis with unrelated operational tasks. Ask which duties will actually be performed and how they relate to the proposed profession, rather than relying on the word consultant.
Identify the qualifying credential and practice question
Keep the real degree, licence or stated alternative required for that profession. Degrees from institutions outside Canada, Mexico or the United States need reliable foreign-credential evaluation; translating a credential is a different task. Any licence required for U.S. practice must be assessed separately. A client’s acceptance of a résumé cannot waive the immigration credential test or grant professional practice authority.
Explain ownership and the recipient of the services
Show who contracts for and receives the work and what relevant ownership or control exists. Providing services to a U.S. entity solely owned or controlled by the applicant is prohibited under TN. Ownership of a foreign business alone is not a blanket bar. A contract routed through a Canadian company does not automatically make the actual U.S. work permissible; its substance needs review.
Use the actual citizenship and temporary-work process
Canadians generally may seek TN admission without a TN visa; Mexicans generally require the visa. The arrangement must remain qualifying temporary work. Identify any additional engagement before assuming one permission covers another client or employer. A signed commercial contract does not itself authorize the activity or set a guaranteed admission date.
Know which procedure applies to a Canadian citizen
The letter should state the profession by its listed name, describe duties that are forestry duties, such as inventory, harvest planning, regeneration assessment and compliance with state forest-practice rules, and give the location, remuneration and intended length of stay. The diploma definition concerns at least two years at an accredited Canadian or U.S. postsecondary institution; the certificate has defined Mexican program and issuer requirements. For a Canadian citizen, the usual initial request is made to a CBP officer when seeking admission; an employer may instead submit an I-129 petition to USCIS for an extension or change of employer. A Canadian citizen applies at a land border, a preclearance post or an airport port of entry with the passport and the supporting file, or the employer may file Form I-129 in advance. Compare that description against the engineering profession's recognized scope rather than the title on the offer letter. Compare the transcript, award document and any evaluation with the precise listed occupation before commissioning extra evidence. The applicant should also warn the institution promptly about a changed departure date, a delayed credential evaluation or a family circumstance that moves the start, because an institution told late may already have offered the position to someone else. For a Canadian citizen, one procedure is to request classification at a U.S. inspection location or a preclearance facility; the employer may alternatively request Form I-129 approval from USCIS.
