IN THIS GUIDE · Assess an additional professional offer on its own terms
Start with the TN eligibility and application overview
Keep the offers distinct
Hypothetical example: an applicant considers a second part-time professional role while keeping the first. List each employer, duties, compensation and expected period. Have the required process for the actual additional employment assessed before starting it.
Apply the listing to each activity
TN principals require Canadian or Mexican citizenship and the qualifications prescribed for the listed professional activity. A similar job title does not establish identical duties. Evaluate degrees, licences or permitted alternatives against the actual profession rather than relying on the earlier offer.
Explain ownership and practical control
Identify the actual employing entities and any 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. An added contract does not resolve a prohibited arrangement.
Preserve accurate records of permission
Review the current admission, existing employment terms and the proposed new activity. Do not imply that a professional credential, customer relationship or prior TN decision automatically extends authorization. The exact process depends on the actual circumstances.
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.
Provincial licence and U.S. practice are two questions
Management Consultant permits a baccalaureate or licenciatura degree, or equivalent professional experience established by a statement or professional credential attesting to five years as a management consultant or five years in a specialty related to the consulting agreement. USMCA Appendix 2 lists "engineer" with its own credential path: a baccalaureate or licentiate degree in engineering, or a state or provincial licence. Ask the employer to confirm the technical proportion of the role in writing and ask the applicant to gather licence and transcript documentation specific to their engineering field. A licence satisfying a TN credential alternative does not necessarily permit practice in another jurisdiction. For a Canadian citizen, the usual initial request is made to a CBP officer when seeking admission; an employer may instead submit an I-129 petition to USCIS for an extension or change of employer. Field experience, published surveys and professional-society membership help explain the role but do not replace the degree, because the biologist entry has no experience-based alternative. Degree transcripts, licences where the occupation requires them, and experience records may answer different questions. For a Canadian citizen, one procedure is to request classification at a U.S. inspection location or a preclearance facility; the employer may alternatively request Form I-129 approval from USCIS.
