IN THIS GUIDE · Explain the actual professional work behind the proposed schedule
Start with the TN eligibility and application overview
Describe the work and genuine terms
Hypothetical example: an offer specifies a limited weekly schedule for technical work. Identify actual duties, compensation and the anticipated period. TN can involve prearranged full-time or part-time professional work, but the specific listing and applicant qualifications still need assessment.
Apply the exact profession’s credential rule
TN requires eligible Canadian or Mexican citizenship. Review actual qualifications and permitted alternatives. For engineers, the listing provides a baccalaureate or licenciatura degree or state or provincial licence; relevant U.S. practice authority is separate. A reduced schedule does not remove the credential requirement.
Identify the real employer and control
Explain actual employer, customer arrangements and relevant applicant 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. A modest number of hours does not resolve an otherwise prohibited arrangement.
Assess permission for the actual activity
Record where and when the applicant will perform work. A part-time offer, payroll entry or short assignment does not itself authorize U.S. employment. Follow the applicable process and assess genuine changes before relying on the proposed schedule.
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.
Know which procedure applies to a Canadian citizen
Canadian citizens do not need a visa for this category and normally seek admission in person at a land border or a preclearance facility, presenting the passport, the employer's letter and the credentials together. Each USMCA profession has its own qualification rule, and the officer applies the one attached to the profession named in the letter. A Canadian citizen presents the TN application at a U.S. port of entry or preclearance, or the employer files Form I-129; Canadians receive no visa stamp. Different professions have different rules, so an experience-based alternative available for one profession cannot be assumed to apply to another. The issuing institution's transcript or confirmation letter is the record that resolves what the credential actually says. A Canadian TN principal can generally request classification at land-border inspection or preclearance; an employer can instead submit Form I-129 to USCIS where that procedure fits. Choosing an inspection request or an employer petition does not repair a mismatch in profession, credentials, or the employer-directed relationship. Official degree records, transcripts, licences where applicable, and experience letters answer different parts of the analysis; a persuasive duty letter cannot cure a missing qualification required by the selected profession.
