Read the general life across the border overview
A Portugal Cove-St. Philip's household in which the principal will hold L-1B, the spouse runs a bookkeeping practice from home and the elder child is 20 has three separate immigration questions, not one. The L-2 spouse may work incident to status and can continue the practice from the United States. The 20-year-old will lose L-2 status at 21 regardless of the parent's remaining time and needs an independent basis. The younger child may study and not work.
The spouse's practice under L-2
Hypothetical example: the principal is a Portugal Cove-St. Philip's engineer transferring as an L-1B specialist for three years; the spouse keeps the books for a dozen small Newfoundland and Labrador businesses from a home office. Because L-2 spouses are employment-authorized incident to status, the spouse may continue serving those clients from the U.S. address, take on U.S. clients, or seek employment, using the admission record annotated as an L-2 spouse as evidence of authorization. The practice's Canadian corporate and tax arrangements are a separate professional question, but immigration law does not prevent the work. Had the principal been on TN instead, the TD spouse could not have continued the practice at all; this difference alone can decide which route a household chooses.
The child who is 20
Dependant L-2 status is available only to unmarried children under 21. A Portugal Cove-St. Philip's child who is 20 at the family's arrival will lose L-2 status on the 21st birthday, and nothing in the parent's L-1B approval extends it. The Child Status Protection Act does not help here, because it applies to immigrant petitions, not to nonimmigrant dependant status. The child needs an independent basis before the birthday: a student status for a U.S. program, or a work status of their own if they qualify, or a return to Canada. Plan this before the move, not in the month before the birthday, because a change of status requires time and the child must be in valid status when it is filed. A child who simply stays past 21 accrues unlawful presence.
The younger child, school and the family's shared clock
The younger child may attend school as an L-2 dependant without a separate student status; the ICE list of classes that may study confirms this. The child has no work authorization, so a summer job is not permitted. Every dependant's status ends when the principal's does, so an L-1B extension application must be filed before the family's permitted stay expires, and the spouse's work and the child's schooling continue only while that is maintained. L-1B is capped at five years in total. If the household hopes to stay permanently, the immigrant route has to be pursued separately, and at that stage the older child's age would be assessed under CSPA using the petition and visa dates.
