A factual description of the position, pay, and duties, along with the applicant's credential and identity records. Any difference between an internal job posting and the proposed letter should be resolved first.
Confirm the actual job posting matches the letter
Compare the original job posting or internal role description against the drafted support letter, and resolve any material difference before the letter is finalized.
Before signing, reconcile the support letter with the dealer's approved posting, organization chart, customer scope, payroll terms, and expected work locations. TN evidence is an employer letter or contract; it should identify the prearranged professional activity, duration, compensation, and duties without adding facts the underlying records cannot support. Confirm Canadian or Mexican citizenship, name the asserted profession in Appendix 2 to Annex 16-A of the USMCA, and verify its particular minimum credential. Determine whether a licence, degree record, or reliable credential evaluation is actually material. The usual error is polishing a letter while leaving a contradictory repair-focused posting unchanged. Prearranged activity may serve either a United States employer or a foreign employer; self-employment remains forbidden.
Hypothetical example: An industrial-machinery engineer from the Tecumseh area receives a dealer letter describing design analysis, while the internal requisition says mobile repair technician. Before execution, the dealer compares duty percentages, removes neither inconvenient fact, and obtains the engineer's citizenship and degree evidence. It also confirms who directs the work and whether the applicant owns any receiving enterprise. A corrected, factually consistent contract is more useful than an aspirational professional title unsupported by the operational documents.
