The second person needs their own appropriate authorization. One applicant’s successful process does not establish that the teammate may work.
Build the project timetable from actual individual outcomes
Coordinate with the employer without promising simultaneous decisions. A shared deadline cannot replace the second person’s citizenship, qualification or process requirements.
A professional order may take weeks to issue a confirmation of standing, a university transcript request has its own queue, and a U.S. employer's legal department may revise the letter several times. An in-person application at a land border or preclearance facility produces a same-day answer with no visa required; an employer petition on Form I-129 takes longer but leaves a written record and a decision that can be reviewed before anyone travels or resigns. A Canadian citizen may request TN admission at an eligible port of entry or preclearance location, or a prospective employer may file Form I-129, but neither option converts incomplete licensing or certification into permission to practise. Ordering official copies from an institution or professional order and arranging certified translation both take time that is difficult to compress, and neither should be squeezed against a start date already promised to an employer. Once admitted, record the TN expiry and the licence and certification expiries side by side; the renewal sequence should begin several months before the earliest of them so the second entry does not repeat the first delay.
