Before preparing a filing or relying on the job for admission. Allow the technical manager to confirm methods and responsibilities, then reconcile that account with HR’s offer. A deadline for starting a forecast project does not itself authorize work.
Include preliminary model work in the schedule
The first assignment might be model setup or data validation before the published project launch. List those activities, their location and expected dates for review. The lawful start must account for the actual work, not merely the date the employer intends to present the finished forecast.
Agree when the institution will confirm, revise or withdraw the offered start. A TN admission may be granted for up to three years and can be renewed while the qualifying employment continues, with no fixed lifetime maximum. Begin as soon as the employer's intent is in writing. A paid benefit cannot guarantee admission or make an otherwise premature work start permissible. Next comes the U.S. employer's signed support letter, then the venue decision. TN admission is granted for a defined period, extensions are possible, and each one is assessed afresh against the same occupational and qualification tests. The port-of-entry application itself takes a day, but only once those exist.
