Material differences should be resolved before the terms are presented as settled.
Use the actual proposal
A desired start date does not justify choosing an inaccurate description. Review the corrected engagement and applicable process instead of assuming the earlier assessment remains valid.
Pause submission until the employer identifies the controlling offer and corrects both language versions. Recheck the chosen USMCA profession, its qualification rule, the real duties, duration, pay, and supervision after the correction; an earlier eligibility view may no longer fit. Canadian or Mexican citizenship remains essential, and Canadian permanent residence alone does not satisfy that condition. Confirm that the work is prearranged and not self-employment, including disclosure of ownership. Once the record is settled, a Canadian applicant can decide whether to seek classification at a port of entry or have the employer use Form I-129. Rushing with the favourable wording commonly creates a credibility problem that a desired start date cannot erase.
Hypothetical example: a Magog forester receives one offer describing forest-inventory analysis and another assigning general procurement for a U.S. timber company. With travel approaching, she should ask the company to freeze the start plan, settle the duties, and issue a corrected letter before selecting a process. Her forestry degree and project schedule matter only if the final work actually corresponds to the listed Forester profession. Carrying the preferred draft while the company debates the job would make the proposal look unresolved.
