IN THIS GUIDE · Assess the revised offer before assuming an earlier TN plan still fits
Start with the TN eligibility and application overview
Identify the profession in the current work
TN is available to qualifying Canadian or Mexican citizens for temporary work in listed professions. The applicant must meet the particular profession’s prescribed qualifications; experience replaces a degree only where its rules permit. Compare the genuine revised duties with the proposed profession rather than preserving an outdated job description because it was used before.
Recheck credentials without treating the offer as a licence
Degrees from institutions outside Canada, Mexico or the United States need a reliable foreign-credential evaluation. Translation is separate, as is any licence required for U.S. practice. An employer may value the applicant’s experience while the immigration credential rule still needs to be met. Record the actual qualification supporting the current professional activity.
Read the new employing structure
Providing services to a U.S. entity solely owned or controlled by the applicant is prohibited under TN; ownership in a foreign business alone is not a blanket bar. Identify the real employing entity and any relevant control changes. A payroll change, merger announcement or familiar trading name should not be treated as proof that the previous arrangement remains identical.
Coordinate changes with the applicable process
Canadians generally may seek TN admission without a TN visa; Mexicans generally need the visa. The work must remain qualifying and temporary. Assess additional employers or changed activities through the appropriate process before relying on the earlier permission. A revised start date in an offer letter cannot authorize work or guarantee admission.
Confirm the qualification that the profession itself names
A job title like 'systems engineer' or 'product engineer' does not by itself confirm which USMCA profession applies, and engineering credentials vary by discipline and licensing jurisdiction. Where a technologist can obtain a provincial engineering licence, the listing's alternative becomes available, and the licence is a clean document for an officer to read. Meeting a TN credential alternative does not automatically confer every licence or authorization needed to practise in the U.S. jurisdiction. Every Appendix 2 profession carries its own qualification rule, and Graphic Designer offers two: a baccalaureate, or a post-secondary diploma together with three years of experience. Management Consultant permits a baccalaureate or licenciatura degree, or equivalent professional experience established by a statement or professional credential attesting to five years as a management consultant or five years in a specialty related to the consulting agreement. Biologist is not written that way: the entry calls for a baccalaureate or licenciatura degree, and nothing else is offered as a substitute. A Canadian citizen can request TN classification from CBP on arrival or at a preclearance facility; an employer may instead submit Form I-129 to USCIS for the worker. Keep the transcript, the degree parchment and the evaluation together, and check whether the degree title on the parchment matches the wording of the entry, because a variant title is the point most often queried.
