A title change does not settle whether the actual duties or employer arrangement changed. Have the real proposed work and necessary process assessed before relying on existing permission.
Record substantive changes honestly
Keep the original and revised responsibilities identifiable. A preferred start date or simplified title does not establish authorization for different activity.
Set a specific milestone for receiving corrected, consistent documents, and only build the rest of the timeline, including any planned start date, around the confirmed corrected assignment dates. Work backward from the employer’s last workable start date, allowing time to obtain the contract, citizenship proof, and the credential evidence required by the selected USMCA profession. A first review should produce a sequence: resolve the professional match, collect the executed terms, select the procedure, and travel only when the record supports the request. For a Canadian citizen, coordinate either a port-of-entry TN request before work begins or the employer’s petition and resulting authorization; Canadian permanent residence alone is insufficient. Once the record is stable, a Canadian outside the United States may request TN classification at a port of entry or the US employer may first file Form I-129; after approval of an advance petition, the Canadian must still seek admission.
