Start with the TN eligibility and application overview
Assess the actual activity and offer
TN requires Canadian or Mexican citizenship, a listed USMCA profession and its particular qualifications for the prearranged engagement. Describe duties, employer, remuneration and duration accurately. A demonstration label cannot replace the analysis of real activity or the existence of an actual proposal.
Use the appropriate immigration process
Review ownership, including prohibited self-employment through sole or controlling ownership of the US enterprise receiving services. Canadians generally may seek TN admission without a visa; Mexicans generally need a TN visa, with petitions where appropriate. An invitation, employment discussion or unpaid label is not a universal work-authorization exception. All ownership stakes must be disclosed. Canadians may apply at a port of entry or through an employer-filed Form I-129.
Temporary work and credential review
TN is for qualifying temporary professional activity. Degrees from institutions outside Canada, Mexico and the United States require a reliable foreign-credential evaluation. Any licence needed to practise in the United States is a separate issue from the listed TN qualification. A foreign business interest alone is not a blanket bar; the self-employment concern described here concerns the US enterprise receiving services.
Hypothetical example: a registered nurse recruited through a staffing agency
Hypothetical example: a Sooke registered nurse is recruited by a US staffing agency for a hospital contract in another state. The agency's email says the job is ready and asks her to drive to the border next week. The TN Registered Nurse credential rule requires a state or provincial licence or a Licenciatura degree; separately, 8 CFR 212.15 requires a health-care worker certificate from an approved organization to be presented at the port of entry. The agency cannot waive the certification, and any destination-state authorization needed to practise must also be obtained before work begins. The sensible sequence is: identify the credential that meets the TN rule, determine the destination state’s licensing or temporary-permit requirements, complete the certification screening, then ask the agency for an employer letter that identifies the employer and the specific hospital placement, duties, pay and contract length. Only after the admission documents are in hand should she present herself as a TN applicant.
Decide who the employer is before the letter is written
Agency placements raise a question the officer will ask: who is the employer? The TN letter must come from the entity that pays and controls the work, and it must describe the professional duties rather than the placement generically. A Canadian citizen may apply at a port of entry or through an employer's I-129 petition; either way the letter, the licence and the certification are examined together. A spouse or child accompanying the nurse in TD status may study but cannot work in the United States.
Hypothetical example: a lodge assistant manager and three vague experience letters
Hypothetical example: a Sooke lodge’s assistant manager is offered a resort management position by a US hospitality company. He holds a two-year hospitality management diploma and has worked in lodges for six years. Hotel Manager is a listed profession whose qualification is a degree in hotel or restaurant management, or a post-secondary diploma or certificate in that field plus three years of experience in hotel or restaurant management. His diploma is in the right field, so the case turns on the experience. What usually goes wrong is the proof: his three former employers write two-line letters saying he was ‘a valued member of the team’. The officer needs dates, titles and duties showing management of a hotel or restaurant operation, not tenure in one. Ask each employer for a letter on letterhead listing start and end dates, the position held and the responsibilities actually exercised, and attach payroll records where a letter cannot be obtained. The US letter must describe management duties, the pay and the term; any ownership interest must be disclosed, and the arrangement must not amount to self-employment through sole or controlling ownership. He may apply at the port of entry.
