Assignment-based work can be shorter or less predictable than a direct offer, which matters when a spouse and children are relocating. TD, where it applies to a spouse or unmarried children under 21, permits study but does not authorize employment, so a second income cannot be assumed.
Plan the household around the assignment's real term
Ask the agency what term the client contract runs for, whether extension is at the client's discretion, and what notice applies. That term, not an optimistic expectation, is the honest basis for school enrolment and housing choices. Confirm each dependant's own documents early, since procedural steps differ by nationality, and keep commitments reversible while the assignment length remains uncertain.
The spouse and unmarried children under 21 of a TN professional may be admitted in TD status for the same period as the principal. A qualifying spouse or unmarried child under 21 may seek TD, subject to individual requirements. TD does not authorize employment, and location uncertainty does not create an exception. TD does not authorize employment, including work described as consulting. Keep the spouse’s proposed job and authorization separate from the employer’s patience with the principal’s credential documents.
Avoid budgeting as though departure is impossible; admission can still be refused, employment can end, or family plans can change.
