Start with the TN eligibility and application overview
Match duties before titles
Job titles can be vague. Compare the day-to-day duties with the specific Appendix 2 occupation and its education, credential, or experience rule. A polished letter that uses a listed label without explaining the work can leave the central issue unresolved. The employer should state why the role needs the professional services claimed. Read the employer’s draft against project documents and remove duties that belong to another occupation. Ask whether the role can be described truthfully under one listed category, not whether a broader title sounds senior.
Confirm the qualifying person
Citizenship evidence, credentials, and any licence should be reviewed together. A degree from outside North America may require a careful equivalency assessment where that is relevant. Some occupations have alternative qualification routes, while others do not. Experience should not be assumed to cure every educational gap. Where a licence is relevant, determine whether the position requires it on the first day or merely describes later professional development. The governing record is the applicable licensing rule, not an informal statement from a recruiter.
Keep the employer relationship genuine
The proposal should identify the US employer, compensation, location, supervisory arrangement, and intended temporary period. Consulting arrangements need special care because a client contract and the employer’s offer may describe different work. Ownership or control that makes the person effectively their own US employer can create a prohibited self-employment problem. Ask whether the company retains ordinary hiring, payroll, and supervisory authority. A contract invoice, ownership interest, or client direction can reveal a structure that needs separate analysis.
Select the correct route for the facts
Canadian citizens commonly seek TN classification at a border inspection location or airport preclearance facility, and an employer can also pursue an I-129 route with USCIS; a Mexican citizen ordinarily applies for a TN visa at a United States consular post before travelling. The process chosen does not reduce the evidence needed. Any admission record and later change must be checked against the actual work that will be performed. A Canadian citizen may seek classification during inspection, while the employer may instead obtain an approved I-129 from USCIS. Either path requires prearranged professional services for a separate employer; TN cannot authorize a self-directed U.S. business.
