Yes, at least the commitments that are costly to reverse. Dependent TD arrangements depend on the principal's case proceeding, and a licence question can change the timeline or the route. Keep housing, schooling, and notice periods provisional until the credential position is settled.
Do not let the household get ahead of the file
A lapse discovered late can push a start date by months if reinstatement is required, and families that have already moved absorb that cost directly. Settle the credential and licensing position first, then commit. If a spouse is counting on working, address that separately: TD permits study but does not authorize employment, so the spouse needs their own basis for any job.
TD may be available to the spouse and unmarried children under twenty-one of a TN professional, and the steps depend on each person's nationality rather than on where the family currently lives. The principal’s employer may offer an opportunity without providing the spouse’s permission. Assess the spouse’s proposed activity and independent authorization rather than assume the principal’s classification covers the household. Treat the principal’s TN evidence and the spouse’s intended activity as two separate files. A Canadian principal may seek TN at entry or through an employer's Form I-129, but neither method changes TD work limits or permits principal self-employment.
