Read the general life across the border overview
Hypothetical example: a household is planning a move with children aged nineteen and twenty-one. Under TN, L-1 and E-2 dependent classifications, an unmarried child must be under twenty-one, so the older child is outside those classifications and the younger has an age-out deadline. An immigrant case may involve statutory age protection that must be assessed from its filing dates and visa availability. Identify the earliest fixed date and give each person a separate line in the plan. Hypothetical example: a pastry-equipment technician plans to relocate with a spouse and two children, one of whom will turn twenty-one during the hoped-for move. The decision is whether the family can use a shared timeline or needs an independent school or work plan for that child now. Put the birthday, likely filing events, and school dates in one calendar; a vague expectation that the family will travel together is not a plan.
Write every date of birth on the plan
The first task is arithmetic rather than law. Put each family member's date of birth beside the intended travel date and the realistic decision dates for whichever route is being used, and mark the point at which any child reaches twenty-one. That single sheet usually reorders the whole plan, because it shows which deadline arrives first and whether it lands mid-school-year. Where a permanent-residence process is involved, published statutory age protections may apply and their operation depends on filing dates and visa availability rather than on the birthday alone, so the sheet should be revisited whenever the expected timeline moves. Recalculate whenever the case timeline moves. The date that matters may be a filing or availability event, so an old calendar can give false comfort.
Give the older child an independent route now
A child past the applicable age boundary cannot use that dependent classification and needs an independent basis unless an immigrant case preserves the child's age under the Child Status Protection Act. A study route may be one option, but it has its own admission, status, timing and financial requirements. Start that analysis in parallel rather than assuming the parents' route covers the child. TD, L-2 and E dependent children do not receive employment authorisation through those dependent nonimmigrant classifications; L-2 and E spouses are different because qualifying spouses are employment-authorised incident to status. A person admitted as an EB-5 derivative conditional permanent resident may work as a permanent resident. Give each adult or near-adult a separate evidence checklist. School admission, work plans, and immigration status are related but not interchangeable answers.
Set out each person's permissions in a table
Permissions differ by person and by category, and the assumption that a household shares one set of rights causes most of the planning errors here. Spouses of treaty investors and of intracompany transferees are employment-authorised incident to status; dependants of a professional worker under the reciprocal North American arrangement are not. Children may generally study under the published guidance on which nonimmigrant classes may do so. Write the table before committing to schools, housing or a resignation, because it frequently changes which route the household should be pursuing at all. Before paying deposits, write down who may study, who expects to work, and what independent authorization would be necessary. This is the decision record a household needs when comparing routes.
