Start with the TN eligibility and application overview
Ask what the institution has actually confirmed
A listed USMCA profession carries particular qualification requirements for temporary TN activity by Canadian or Mexican citizens. Check whether the necessary credential has actually been earned and what reliable evidence establishes that fact. Experience is not a universal substitute for education, and an expected qualification should not be represented as already awarded. The review should produce a short duty-to-profession comparison, a credential inventory and a list of missing records. That sequence exposes a frequent problem: a persuasive job title can hide duties that do not fit the selected profession, or a transcript can show study without proving the required award. If a licence is relevant, determine whether the proposed activity requires it now and obtain the issuing authority’s record rather than relying on an employer’s assumption.
Keep the other TN conditions in view
Degrees earned outside Canada, Mexico or the United States require reliable foreign-credential evaluation; any US practice licence is considered separately. Identify genuine professional duties, employer, remuneration and duration. Applicant-controlled or solely owned US businesses cannot be used for prohibited TN self-employment, while a foreign business interest alone is not a blanket bar. Canadians generally may seek visa-exempt TN admission; Mexicans generally need the visa process, with appropriate petition options reviewed separately. Decide early which admission mechanism fits the facts. A Canadian ordinarily requests TN classification from CBP while seeking admission; an employer can use the I-129 process with USCIS when that procedure is appropriate. The support letter should identify the employer, temporary role, pay, worksite and planned period, with records that agree. TN cannot be used as a route for the applicant to provide services through a U.S. enterprise the applicant owns or controls. Clarifying that point before filing prevents a polished package from resting on a prohibited work arrangement.
The credential attached must match the profession’s own rule
TN turns on the credential alternatives written into the specific profession's listing, not on a general notion of equivalency, so counsel should confirm which alternative the applicant is relying on before anything is drafted. A port-of-entry application gives a same-day answer; a Form I-129 petition gives a written approval before travel and suits a file with a prior refusal, an experience-based credential or an ownership stake. Some institutions will reissue a diploma or transcript under an updated legal name, while others will only provide a letter confirming that the record belongs to the person now using a different name. Present the documents so the connection is obvious without narration: the original diploma, the transcript, the registrar's letter identifying the predecessor and the merger, and any translation or evaluation with its source document attached. Land Surveyor is satisfied by a baccalaureate or licenciatura degree, or by a state or provincial or federal licence. Some occupations accept a post-secondary diploma plus three years of experience; others accept only a baccalaureate; a few accept a licence in place of a degree.
