Read the general professional work overview
A pattern of short U.S. trips is easy to document and tells an officer almost nothing about the assignment. TN admission is granted for a specific professional activity, with a specific employer, for a stated period. Build the file around the work — the listed profession, the credential, the duties, the pay — and let the travel plan follow from it rather than stand in for it.
Connect the dates to the actual activity
Hypothetical example: a Niagara Falls hydraulic-systems specialist expects to spend three days most weeks at a U.S. plant, returning home each Thursday, and keeps a Canadian residence and payroll. That itinerary raises two separate questions and answers neither. The first is what she will do while admitted: the listed profession, the duties, who supervises them, the remuneration agreed and the period the engagement is expected to run. The second is whether each admission remains genuinely temporary in purpose. Commuting arrangements are permitted, but a routine that has continued unchanged for years invites the question whether the stay is still temporary, and the answer has to come from the engagement’s own end point rather than from the applicant’s assurance about it.
Prove the profession and the credential separately
Two documents do different jobs and are constantly confused. The first establishes citizenship: TN principals must be citizens of Canada or Mexico, shown by passport, and no length of Canadian residence substitutes for it. The second establishes the qualification the listed profession itself demands — for most entries a baccalaureate or licenciatura, for some a post-secondary diploma or certificate together with three years of experience, for others a state or provincial licence. Match the entry first, then match the evidence to that entry. Where the degree was awarded outside Canada, Mexico or the United States, a credential evaluation is needed to establish equivalence, and a certified translation is a different document that renders the text without assessing anything. Relevant experience does not universally replace a required degree; it counts only where that profession’s own rule permits it.
Review the employment and ownership arrangement
Recurring travel makes changes easy to miss. If the employer changes, the duties shift into a different profession, or the assignment moves from one U.S. entity to another, the previous admission does not carry across — a fresh TN determination or an amended petition is needed, and familiarity at the border is no substitute for one. Ownership needs stating plainly: providing services to a U.S. entity the applicant alone owns or controls falls outside TN, though holding a minority interest, or working for a company that happens to be foreign-owned, is not automatically disqualifying. Procedurally, a Canadian citizen ordinarily seeks TN admission at a port of entry or a preclearance facility, or through an employer-filed Form I-129, with no TN visa stamp issued; a Mexican citizen ordinarily obtains the visa first. Neither route removes temporary intent, and neither supplies the practice licence a regulated profession requires under state law.
