IN THIS GUIDE · Distinguish ownership of a Canadian company from control of the U.S. services recipient
Start with the TN eligibility and application overview
Identify the actual recipient and control
TN prohibits services to a U.S. entity solely owned or controlled by the applicant. Foreign business ownership alone should not be turned into a blanket prohibition without assessing the actual U.S. arrangement. Start with corporate records, not a trade name: the share register, operating agreement, voting rights and engagement letter may show whether the U.S. recipient is independently controlled. The decision is whether the proposed work is for that recipient or for the applicant's own U.S. enterprise.
Describe genuine professional activities
Hypothetical example: a Canadian owner has an offer from a separate U.S. enterprise. Identify real duties, the actual employer or arrangement and temporary terms. The existence of a separate company does not by itself establish qualifying professional work. Compare the duty description with the applicable USMCA profession before preparing a support letter. A polished job title cannot cure duties that are chiefly sales, routine administration or another non-listed activity. The reader needs an honest match between the offered role and the professional category.
Preserve citizenship and prescribed qualifications
The principal needs Canadian or Mexican citizenship and the listed profession’s qualifications. Experience is not a universal degree substitute. Degrees from institutions outside Canada, Mexico or the United States require reliable foreign-credential evaluation. Put the passport, degree, transcript, evaluation where needed, licence evidence and employer letter in a sequence that lets the reviewer test each requirement. A credential may establish education without proving the offered duties, so the two records should not be treated as interchangeable.
Review substance rather than a commercial label
A consulting agreement, invoice or ownership restructuring does not automatically establish eligibility. Explain actual relationships and control honestly. A private contract does not grant U.S. work permission. Hypothetical example: a hydrogeologist employed by a Corman Park groundwater-testing firm receives an offer from an unaffiliated U.S. environmental laboratory. Before travel, she must decide whether her materials describe laboratory-directed analysis or a plan to sell her own services. The signed offer, reporting line, invoices and share register resolve that distinction more reliably than the word consultant.
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. Before relying on travel dates, identify whether the person is a Canadian or Mexican citizen, who will submit the request and what activity begins after admission. A requested admission period is not a permission to change into unrelated work, and beginning outside the documented arrangement can create a separate compliance problem.
