IN THIS GUIDE · Separate several proposed professional roles before choosing a TN basis
Start with the TN eligibility and application overview
Match each real role to its profession
TN requires Canadian or Mexican citizenship and qualifying temporary professional work in a listed USMCA profession. Each profession has prescribed qualifications and its own permitted alternatives; experience is not a universal degree substitute. Identify the tasks in each proposal rather than combining different offers into a single idealized job.
Use the credential that actually meets the rule
A degree from an institution outside Canada, Mexico or the United States needs reliable foreign-credential evaluation. Translation is a separate requirement where relevant, and U.S. professional practice licensing must be assessed separately. An employer’s willingness to accept a qualification does not waive the immigration profession’s prescribed standard.
Keep employers and control arrangements distinguishable
Providing services to a U.S. entity solely owned or controlled by the applicant is prohibited under TN. A foreign business interest alone is not a blanket bar. Identify the actual employer and relevant ownership for each proposal; one company’s structure cannot answer the control question for another.
Assess additional work before relying on one permission
The work must be qualifying and temporary, and each additional employer or materially different arrangement needs the appropriate assessment and process. Canadians generally may seek TN admission without a TN visa; Mexicans generally require the visa. An offer’s acceptance deadline or a schedule that leaves spare hours does not create additional work authorization.
Check the profession’s exact requirements
Industrial contracting employers often use "engineer" loosely for roles that are properly engineering technologist or technician positions, which sit under a different Appendix 2 entry with its own rules. Obtain the signed contract first, then the letter written from it, then the diploma with transcripts and three or more years of experience confirmed by former employers in writing. A Canadian citizen may apply at a port of entry or a preclearance location with the complete packet, or the employer may file Form I-129 in advance and provide the approval notice. Write down the exact name shown on each document the case will rely on: passport, birth certificate, degree, transcripts, any professional licence, prior employment references and the employer's support letter. For a Canadian citizen, direct TN processing can occur through CBP at border inspection or preclearance; an employer may also pursue a USCIS Form I-129 petition. A first review normally identifies the transcript, credential assessment, licence, or employment record that resolves each qualification issue and exposes a mismatch before travel is planned. Credential requirements vary by profession, so check the exact listing and raise any borderline case with counsel. Choosing an inspection request or an employer petition does not repair a mismatch in profession, credentials, or the employer-directed relationship.
Get the offer letter to match the entry
Gather citizenship evidence and the degree, licence, registration, or experience documents that correspond to the particular occupation. Proof of Canadian citizenship, the degree parchment or an official transcript, and a letter from the U.S. company describing forestry work in the profession's own terms, the expected pattern of deployment, the period and the remuneration. Meeting an education-and-experience alternative does not convert a general marketing or account-management offer into the listed profession. Canadian citizens present the file at a port of entry or the employer files Form I-129; no visa stamp is issued. Compare the award date, program name, and credential level across the diploma and transcript.
