Start with the TN eligibility and application overview
Identify the professional role
TN requires Canadian or Mexican citizenship, prearranged work in a listed USMCA profession and the profession’s particular qualifications. Describe the actual duties rather than selecting a category from a payroll label. Experience is not a universal education substitute.
Explain the organizations and procedure
Identify who offers, directs and pays for the work, and provide actual remuneration and duration. TN does not permit U.S. self-employment; disclose all ownership interests so the actual arrangement can be assessed. Canadian citizens may apply for TN classification at a port of entry or preclearance location without a TN visa, or through an employer-filed Form I-129; Mexican citizens generally use the visa route. An administrative arrangement needs accurate explanation, not an assumed result.
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 laboratory technologist placed through a staffing agency
Hypothetical example: a Saanich medical laboratory technologist accepts a thirteen-month contract from a US health-care staffing agency that will place her in a hospital laboratory. The agency is the employer; the hospital supervises the bench work; a separate payroll company issues her pay statements. The USMCA entry for medical laboratory technologists requires a bachelor’s degree or a qualifying post-secondary diploma or certificate plus three years of experience. Separate state licensing rules determine whether she needs a clinical laboratory personnel licence before reporting patient results, and the federal health-care-worker certification requirement must also be addressed before admission. The strongest file is a letter from the agency, as the employer, that names the hospital, the laboratory director who will supervise her, the department, the shift pattern, the salary and the exact contract dates, with the agency–hospital placement agreement as an exhibit. She discloses that she owns no part of the agency or the hospital. Because the position is on the agency’s payroll, the agency, not the hospital, is the party that must intend to employ her for the stated temporary period and whose letter should set that out.
Build the agency file in the order it will be read
First, confirm whether the destination state requires a laboratory-personnel licence and obtain any required licence before clinical work begins; a pending state application does not itself bar TN classification when the applicant otherwise meets Appendix 2. Obtain the health-care-worker certification required for admission in this covered occupation. Second, secure the agency letter and the placement agreement, and check that the job title matches the USMCA profession rather than an agency job code. Third, carry the degree or qualifying diploma-and-experience record and proof of Canadian citizenship. Canadians apply at the port of entry or through an employer’s Form I-129 without a visa stamp. A spouse admitted in TD status may study but cannot work, and any equity or profit-share in the receiving enterprise must be disclosed rather than discovered.
