Read the general life across the border overview
Family planning inside an immigration file is largely arithmetic. A child’s twenty-first birthday, the order in which people are admitted, the date a qualifying relationship existed and the date a category becomes current each settle something no letter can argue around. Put every one of the family’s dates on a single page before choosing between a staged move and a single one.
Put every date on one page first
Hypothetical example: an unmarried child turns twenty-one during the year a household expects to spend waiting. That one date can change which relationships still count as derivative, so it belongs at the top of the plan rather than in a footnote. Record each person’s citizenship or permanent residence separately — a Canadian permanent resident card is not Canadian citizenship, and it does not create TN eligibility for the person holding it. Record the date each qualifying relationship began, the date of each filing, and each person’s own intended activity in the United States. Where an age question arises, the Child Status Protection Act analysis turns on that individual’s dates and on visa availability; there is no automatic freeze at the moment of filing, and assuming one is how families lose a year.
Dependent status is not a shared permission
Each family member’s own activity, not the principal’s category, decides what that person may do. TD confers no employment authorization whatsoever, including work performed for a Canadian employer while the person is physically present in the United States. A qualifying E or L spouse is employment authorized incident to valid status and may work on the strength of that status with appropriate evidence, so a separate employment authorization document is not universally required. Children acquire no work permission simply by being derivatives, whatever their qualifications. Dependants in TD, E and L status may enrol in study while maintaining status, but studying neither extends the status nor creates an independent one, and it never converts a dependant into a principal applicant.
Immigrant routes count relationships, not intentions
On the immigrant side the qualifying relationships are defined and finite. An EB-5 investor’s spouse and unmarried children under twenty-one may be included as derivatives; accompanying the investment makes none of them an investor, and none of them takes on the investor’s management or policy participation. The Gold Card framework asks that intended eligible joining family be named in the initial request, with a separate amount attached to each person, and no professional qualification, household need or private service package widens the set of relationships that qualify. Where a relative falls outside those defined relationships, the honest answer is a separate route assessed on its own facts rather than an argument bolted onto the principal’s file.
Sequence the arrivals around the rule, not the preference
Where a family moves on immigrant visas, the principal applicant must be admitted before, or together with, the derivative family members; a derivative cannot go first and wait. A staged move is still workable, but it must be built around that order and around each person’s own documentation and status on the day they actually travel. Decide who travels first, confirm every traveller holds a document valid on that date, and treat school terms, notice periods and lease dates as constraints to fit around the rule rather than reasons to bend it. An arrival order that inverts the requirement is not a plan the rule will accommodate.
