IN THIS GUIDE · A civil engineer whose U.S. role may not be an engineering role at all
Start with the TN eligibility and application overview
His credential is not the weak point; the company's use of the word engineer is
The Engineer entry in Appendix 2 is met by a baccalaureate degree or by state or provincial licensure, so Oluwaseun's degree and his Ontario registration answer the personal half of the test. What remains is whether the U.S. position is itself professional engineering. Line uptime targets, preventive-maintenance calendars and lean projects are production management; sizing a mezzanine, specifying a foundation for new equipment or approving a structural modification is engineering. An officer compares described duties against the profession, not against the payroll title. A company that wants a maintenance manager should say so, and a company that needs design and analysis should describe that work plainly.
What changes each time the start date moves
Every postponement rewrites the job a little. When the first delay pushed installation of the new line back a quarter, the American plant added shift-coverage duties to fill Oluwaseun's calendar; the second delay added vendor negotiation. Neither addition is engineering, and together they can tip a borderline description over. A slipped date also ages the evidence: an offer letter drafted for a January start describing equipment that has since changed no longer matches reality. Each time the timetable moves, the letter should be reissued to describe the work he will actually perform in the period he will actually be admitted for.
Ownership and self-employment do not become negotiable because the schedule did
TN does not permit self-employment in the United States. If, to bridge the delay, the American manufacturer proposed retaining Oluwaseun as an independent consultant invoicing through his own Ontario corporation while the line is finished, that arrangement would fail whatever his qualifications. He must be an employee of, or under contract to, a U.S. entity that controls his work. Any ownership interest he holds in that entity should be disclosed and would be examined for whether the relationship is genuinely employment. Interim contracting is the most common improvisation when a project slides, and it is the one most likely to end the application.
