IN THIS GUIDE · Two permissions are needed, and only one of them is immigration
Start with the TN eligibility and application overview
The profession entry and the state board answer different questions
The Appendix 2 entry tells you what qualification supports the classification, and for several health professions that is a degree or a provincial or state licence. A state veterinary board tells you whether a person may lawfully practise in that state, which typically involves its own examinations, credential verification and application process. Colin could be admissible in the classification and still be unable to work on the first day because his licence is not issued. The employer should confirm in writing what the destination state requires, whether it offers any temporary or provisional credential, and how long issuance is currently taking, before a start date is set.
The employer letter must describe professional practice
The offer should describe work that requires a veterinarian: herd health programmes, diagnosis and treatment, prescribing, disease surveillance, and the professional judgments that only a licensed practitioner may make. A letter that emphasizes livestock handling, facility inspections and record-keeping describes work that others perform and invites the conclusion that the position does not require the profession. The letter should also state the profession as Appendix 2 names it, the salary, the temporary nature of the employment and the intended period, and it must come from the entity that will employ and pay him. The employer can make this review useful by attaching a short reporting-line chart and a project schedule to the offer. Those records show why the professional work is needed now, who directs it, and whether the work matches the stated temporary period. They are more reliable than a broad recruitment advertisement because they describe the particular assignment rather than an ideal candidate.
Buying into the practice changes the analysis
Practices frequently offer an associate a path to partnership, and that offer interacts badly with a professional classification. TN does not authorize self-employment in the United States, and providing services to a United States entity that the applicant owns or controls falls outside what the classification permits. An ownership interest should be disclosed and assessed on the actual facts rather than assumed to be either fatal or harmless; a small minority interest with no control is a different case from a partnership share. If ownership is genuinely intended, an investment route may be the correct analysis, and it should be examined before an equity agreement is signed.
Present the file once, and present it complete
A Canadian citizen may apply at a port of entry or preclearance location, or the employer may file Form I-129 in advance and provide the approval notice. Canadians receive no visa stamp, so the admission record is the document that proves the classification and its period, and it should be checked and corrected immediately if wrong. Fees follow the published USCIS schedule. A refusal does not bar a later attempt with better documents, but it is recorded, and the practical lesson is to present a complete file rather than to test a partial one.
