IN THIS GUIDE · Explain a genuine part-time professional arrangement
Start with the TN eligibility and application overview
State the real schedule and work
TN may concern qualifying prearranged full-time or part-time professional work. Hypothetical example: an employer needs professional analysis on a limited weekly schedule. Identify that arrangement accurately; the schedule does not itself establish whether the profession fits.
Preserve citizenship and qualifications
The principal must be Canadian or Mexican and meet the listed profession’s prescribed qualifications. Experience is not a universal substitute for a degree. A credential from an institution outside Canada, Mexico or the United States requires the applicable reliable evaluation.
Identify the employer and actual duties
A small number of hours does not turn unrelated work into a listed professional activity. Services to a U.S. entity solely owned or controlled by the applicant remain prohibited under TN. Identify the actual recipient and ownership rather than relying on a contract heading.
Keep additional activities separate
The offer should explain the temporary arrangement and compensation. Other work needs its own assessment; permission associated with one employer is not automatically permission for every activity. An employer’s part-time schedule does not determine immigration authorization.
Apply the temporary-work and credential boundaries
A Canadian citizen generally may seek TN admission without first obtaining a TN visa; a Mexican citizen generally needs the visa. The actual temporary assignment and any required U.S. practice licence remain separate from profession eligibility. A foreign business interest alone does not disqualify an applicant: the prohibited arrangement is services to a U.S. entity solely owned or controlled by that applicant.
Identify which listed profession the duties actually describe
Once the work is clear, identify the relevant USMCA profession and its exact qualification alternatives. A scientific-technician or technologist proposal requires more than an offer to work under an engineer. Some entries require a baccalaureate degree, some accept a diploma with post-secondary experience, and the Registered Nurse entry accepts a state or provincial licence or a Licenciatura degree. A diploma, transcript, licence, or employer letter in another language is the candidate for translation. Canadian or Mexican citizens normally request this classification at a land border or airport preclearance facility, while the employer can submit Form I-129 to USCIS when that route fits the case. The applicant should carry the original licence, degree, transcripts, the signed offer letter, proof of citizenship, and evidence of intent to depart at the end of the period. The first review should produce a short route memo: the exact listed profession, the credential alternative being relied on, the proposed duties, and the document that proves each point. Meeting the TN credential rule also does not provide every licence needed to practise in the U.S. jurisdiction.
Assess the profession rather than the corporate label
Once the degree comparison and licensing question are answered, assemble the job offer, duty description, transcripts, evaluation report, and any licensing correspondence into one file the reviewer can assess as a whole. Institutions differ in what they offer: a replacement parchment, a certified true copy, an official transcript, or a registrar's letter confirming the degree and conferral date. Confirm as well that the letter describes the profession by the qualification actually relied on, since the profession-specific requirement is assessed against the person’s credentials rather than against the job title the company happens to use internally.
