Review the actual duties and terms then offered. Do not continue using the earlier proposal as though nothing changed.
Preserve the final version
Identify the changed responsibilities and relevant qualification. A budget approval date does not automatically authorize work or set an admission outcome.
Set dates for receiving the employer letter, credential review, licence confirmation, family document checks, and the intended immigration procedure. Allow time for the evaluator to review the foreign program, request any missing records, and issue a report, then time for the employer to confirm whether licensing applies. Work backwards from the first date the applicant must lawfully be doing the work, then insert the steps that have to precede it: the structural review, any restructuring the employer agrees to, the credential evidence, and the employer letter. Turn the target start date into a sequence of dependencies: settled duties, completed employer letter, credential availability, procedure choice, and travel date. A Canadian outside the country may request TN admission through border inspection or preclearance, or the employer may submit an I-129 petition to USCIS when that route fits the facts. A Canadian citizen may generally request TN admission at a port of entry, and an employer petition is an alternative with its own processing time, but neither compresses the preparation that has to happen first.
