IN THIS GUIDE · Assess the current duties alongside the established career
Start with the TN eligibility and application overview
Describe the proposed job without relying on past titles
Hypothetical example: an applicant formerly performed engineering design but is now offered responsibility for customer accounts. Identify the actual new duties and deliverables. A long engineering career does not automatically make a different proposed job qualifying engineering work.
Apply the precise qualification alternative
Review the particular listing and genuine credential. For an engineer, the listing provides a baccalaureate or licenciatura degree or state or provincial licence. Do not substitute experience wherever the applicable profession requires a degree without a permitted alternative. Separate the TN qualification from any authority needed to practise regulated activities in the U.S. jurisdiction.
Check the actual citizenship and work arrangement
TN requires eligible Canadian or Mexican citizenship, not Canadian permanent residence alone. Explain the current employer, client arrangements and relevant ownership. Services to a U.S. entity solely owned or controlled by the applicant are outside the permitted arrangement; foreign ownership alone is not a blanket disqualification.
Do not treat an earlier file as current permission
Identify the actual process and authorization for the proposed activity. A former approval or similar job description does not itself authorize new work. Explain material changes and genuine current terms instead of assuming the previous record answers every question.
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.
Prove the diploma-plus-experience route with dated letters
An officer reads the offer letter to decide whether the position is professional employment in the listed occupation. A Canadian citizen presents the case to CBP at a port of entry or preclearance location with the employer letter, proof of citizenship, the licence and any supporting transcripts; no visa stamp is issued. Request exact copies of what went to the government or was handed to an officer: the support letter as signed, the agreement as executed, credential documents, proof of citizenship, forms, and any cover correspondence. List the diploma, degree, or professional designation exactly as the issuing institution wrote it, then place a straightforward English rendering beside it rather than replacing it. Use authentic credentials and any expressly permitted alternatives; experience cannot universally replace a degree. Where the diploma-and-experience route is used, ask counsel how the three years are counted in relation to the award, since the answer decides which employment letters are worth chasing. A Canadian citizen professional may request TN admission in a border inspection process or use an employer’s USCIS I-129 petition; neither option permits a self-employed U.S. arrangement.
