Start with the TN eligibility and application overview
Describe the proposed US activity
TN requires Canadian or Mexican citizenship, a listed USMCA profession and that profession’s particular qualifications. Identify actual duties, employer, remuneration and duration. Explain what the US proposal entails rather than assuming the existing arrangement covers every future activity.
Review the relationship and process
Disclose relevant 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 the visa route, with employer petitions where appropriate. Past work from Canada is not itself US work authorization. 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 biologist’s role with technician duties
Hypothetical example: a Highlands biologist with a bachelor’s degree is offered a US position where the letter lists species surveys, data analysis and report authorship, but also thirty percent of time spent maintaining traps, driving field crews and entering data. Biologist is a listed profession requiring a degree. What goes wrong is a letter that reads as a field technician’s job with a degree attached, inviting the question whether the work actually requires a biologist. The employer should describe the professional core honestly: designing the survey protocol, interpreting results, signing reports relied on by regulators. Incidental field tasks that a professional ordinarily performs are not fatal, but if the job is mainly technician work the applicant should not seek TN as a biologist. Ask the employer for the actual split, check whether any state licence applies, and confirm the applicant neither owns nor controls the employing enterprise. A Canadian citizen may then apply at the port of entry.
Sequence the evidence
Obtain the duties list before the letter is finalized, then the letter with pay, duration and location, then the degree and transcripts, then citizenship proof. If the degree is from outside Canada, Mexico or the United States, add a credential evaluation. Any ownership interest and its associated control rights should be disclosed; sole or controlling ownership of the enterprise receiving the services raises prohibited self-employment. TD dependants may study but not work, and non-Canadian-citizen dependants need a consular TD visa. Keep the file for renewal, when the description will be compared with the work actually performed.
Hypothetical example: a land surveyor qualifying on a licence rather than a degree
Hypothetical example: a Highlands land surveyor holds a provincial commission earned through articling and examinations but no bachelor’s degree. A US engineering firm offers a position running boundary and topographic surveys for its subdivision work. Land Surveyor is a listed profession, and its qualification is either a degree or a state, provincial or federal licence, so the commission alone meets the listed requirement. The reviewer’s first request is therefore the licence certificate and a current standing letter from the provincial regulator, not a transcript. The second question is separate: a survey that will be relied upon in a US state must generally be signed by someone licensed in that state, and the employer letter should say honestly whether he will work under a state-licensed surveyor’s supervision until his own reciprocity application succeeds. The letter must also describe surveying duties rather than construction-crew management and confirm pay and duration. Any ownership interest and control rights must be disclosed, and the arrangement must not amount to self-employment through sole or controlling ownership. A Canadian citizen may then apply at the port of entry.
