Resuming duties does not itself establish family status or documentation. Review each person’s actual qualifying status and intended activity. Insurance and a school place can be bought; status cannot. A family health policy, an enrolment agreement or a lease each create obligations between private parties, and none of them bear on who may enter, remain or work. Read the immigration position separately from the arrangements being assembled around the move.
Keep employment events distinct from status events
Qualifying L spouses are employment authorized incident to status with appropriate documentation. Children receive no work permission solely through L dependent status. An internal return date does not create these rights before the applicable status exists.
Resuming duties is an internal event and alters nothing for anyone else in the household. Dependants derive their position from the principal actually holding L status, so the order runs one way: establish the principal’s position, then assess each relative on their own relationship, age and intended activity. A qualifying L-2 spouse is employment authorized incident to status once the supporting documentation is in place, while a child in dependent status may attend school and gains no work permission from that status.
Where a child approaches an age threshold or a marriage is planned, raise it early, since the category a person qualifies for can change while the rest of the file stands still.
