Assess every accompanying person's relationship, age, intended activity, and sequence separately.
TN planning question: family
TD status can allow a qualifying spouse or child to accompany or follow the TN principal, but it does not give the spouse general employment permission. Children may attend school subject to applicable status rules, yet that does not create an employment option. Make a row for each family member showing passport citizenship, relationship evidence, intended arrival date, work or study plan, and any independent status possibility.
Hypothetical example: one adult has the professional role and the other wants to keep a remote Canadian position while physically south of the border. The location and nature of the second adult's work need separate legal analysis; the family relationship does not settle it. This exercise often prevents a housing lease or school enrolment from being treated as proof that all activities are permitted.
Discuss practical life plans without turning them into assumed immigration permissions. Housing, childcare, medical coverage, school registration, travel reservations, and remote work arrangements may all depend on the exact status eventually obtained. Build alternatives for a delayed arrival, a split household, or a family member whose intended activity cannot proceed as first imagined.
Keep relationship documents available in long form where possible and resolve name changes early. A family member should not conceal an activity simply because it is unpaid, occasional, or performed online. The honest description of an activity is the starting point for sound advice.
When a family fact changes, update the whole plan rather than adding an informal side note to an outdated principal application.
