IN THIS GUIDE · Read beyond the profession named in the offer
Start with the TN eligibility and application overview
Annotate duties rather than relabel the position
Hypothetical example: an offer calls the applicant an engineer but describes a mixture of design work and routine sales. Identify real responsibilities, expected deliverables and how time will be used. Do not rewrite a business role into a listed profession merely to fit the desired route.
Use the actual profession’s qualification rule
Review the applicable listing and permitted alternatives. For engineers, the listing provides a baccalaureate or licenciatura degree or a state or provincial licence. Authority to practise a regulated profession in the relevant U.S. jurisdiction is a separate question; neither a title nor an employer assurance settles both.
Check who receives and controls the services
Explain the actual employer, any customer placement and relevant ownership. Services to a U.S. entity solely owned or controlled by the applicant fall outside the permitted TN arrangement; foreign business ownership alone is not a blanket disqualification. A clause calling the person an employee should not conceal a different actual arrangement.
Separate contractual dates from authorized activity
Record the proposed work and location, including any preliminary duties. A signed offer does not authorize U.S. employment. Review the appropriate process and actual permission before relying on the agreement’s start date; the contract should not be treated as the government’s decision.
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.
Match qualifications to the specific listed occupation
TN admission for Canadians is available at the port of entry with the letter, the licence and proof of citizenship, or by an I-129 petition filed by the U.S. party. Canadian citizens generally present TN evidence directly at the port of entry rather than obtaining a separate visa stamp; some employers instead file Form I-129 in advance. Some listed professions accept a degree, while others use a particular licence, diploma, or defined experience. An architect job offer raises a specific TN question before anything else: does the applicant's foreign education and licensure match what the architect profession requires under the TN category. Separate refusals rooted in missing paperwork from those rooted in a structural mismatch, such as duties that don't fit a listed profession or a credential the officer found unconvincing. Canadian permanent residence is not enough, and experience does not universally replace the prescribed education. A credential may fit the listed occupation and still leave a state-specific licence, registration, supervision, or employer requirement to investigate before practice begins. An agency’s acceptance of experience does not create a degree alternative absent from the profession’s rules.
