IN THIS GUIDE · Weigh a field-service-and-consulting role against the listed occupation before treating it as settled
Start with the TN eligibility and application overview
Separate field repair work from professional consulting duties
Hypothetical example: an offer for an 'Agricultural Systems Specialist' role lists duties split between routine equipment repair calls and technical consulting on precision-farming software configuration. Get the actual weekly task breakdown from the employer, and keep both kinds of duties in the account rather than emphasizing only the consulting half.
Match qualifications to the specific listed occupation
Confirm which USMCA professional category, if any, actually covers this specific combination of duties, and what credential or experience standard that category requires. An impressive technical background in one area does not automatically satisfy a different occupation's own rule.
Account for the employer relationship in full
Set out the confirmed position, pay, and intended duration, and disclose any ownership interest the applicant holds in the employer or a related equipment dealership. The TN bar on self-employment turns on the real ownership and control facts. In particular, services to a U.S. recipient solely owned or controlled by the applicant are prohibited TN self-employment. Ownership of a foreign business alone does not establish that prohibition.
Match the process to the person
Identify the individual’s nationality and actual procedure before booking travel. Canadians generally may request TN admission without a TN visa, including through an applicable port or preclearance process; a USCIS petition is another option where appropriate. Mexican citizens generally need the consular TN visa process. Review prior U.S. immigration history and establish temporary entry rather than treating an offer as permission to work.
Apply the specific credential rule for the listed profession
Canadian permanent residence is not enough, and experience does not universally replace the prescribed education. Ask which credential the case will actually rest on: a degree, with a reliable evaluation and supporting academic records where it was earned outside Canada, Mexico or the United States, or a qualifying licence, documented by its issuer and current validity. Each listed profession carries its own minimum, and those minimums differ: some accept a baccalaureate, some require a provincial or state licence, and a few recognise experience in place of a degree. The list distinguishes a medical laboratory technologist from a technician, and it requires a baccalaureate degree, or a post-secondary diploma or certificate plus three years of experience. The applicant should carry the original licence, degree, transcripts, the signed offer letter, proof of citizenship, and evidence of intent to depart at the end of the period. Ask which record proves each required qualification: a final diploma, transcript, licence, or carefully matched experience record where an alternative is permitted. Record the issuing institution, degree field, completion date, and any jurisdiction-specific licensing barrier that affects the stated work.
