IN THIS GUIDE · TN for Guelph/Eramosa agronomists and other listed professionals: the letter, the degree and the order of events
Start with the TN eligibility and application overview
The letter describes the wrong job
A port-of-entry officer reads the employer's letter first. If the dominant activity described is selling product, the officer is entitled to conclude that the position is sales, which is not a listed profession, whatever the title says. The letter should describe the professional work in agronomy terms: interpreting soil and tissue analyses, designing fertility and pest-management programs, and advising growers on agronomic decisions. Compensation structure can be mentioned, but a commission-heavy pay scheme with a quota invites the sales reading. Ask the employer whether the role can be honestly framed as advisory work with sales support, or whether it is a sales role with agronomy support; only the first fits TN.
The degree and the profession must line up
The Appendix 2 entry for Agriculturist requires a baccalaureate or Licenciatura degree. A bachelor of science in agriculture, agronomy or crop science fits directly; a diploma, licence or experience alone does not satisfy this entry. Bring the degree certificate and transcript, and if the degree title is unusual, a course list that shows agronomic content. The professional must also hold Canadian or Mexican citizenship. A permanent resident of Canada with another nationality cannot use TN regardless of the degree.
Resignation before decision
Canadian citizens apply for TN at a port of entry or preclearance, or by petition, and no visa stamp is issued. Because the decision can be made in a single interview, applicants often resign first and travel second. When the officer finds a defect in the letter, that applicant has no job on either side of the border. The safer order is: signed letter, documents assembled, admission or petition approval, then notice to the current employer. If the US employer insists on an immediate start, ask whether preparatory work can be done remotely from Canada until the admission decision, which needs no US work authorization.
Ownership, self-employment and intent
TN does not permit self-employment in the United States. If the agronomist is being engaged as an independent contractor paid by invoice, or has been offered equity in the employer, that must be disclosed and may take the arrangement outside TN. Explain the employment relationship as it truly is: who pays, who directs the work, who owns the entity. TN is a nonimmigrant category, and an applicant who has already filed for permanent residence should expect questions about temporary intent, although a pending application is not by itself a bar.
