Bring family questions into the initial discussion, while keeping eligibility decisions separate. Identify who may accompany the principal and whether a spouse plans to work or children plan to study.
Check each person’s intended activities
Qualifying L-2 spouses are employment authorized incident to status; L-2 children do not receive work permission on that basis. Confirm each person’s requirements instead of treating the corporate appointment as family authorization. Make one line per family member and write three things against each: what the person expects to do, what document would show they may do it, and who has to be asked.
A spouse intending to take salaried work needs evidence an employer will actually accept, so the practical question is which record satisfies that employer's verification process rather than whether permission exists in principle. A child intending to study needs the school's own admission requirements checked separately, because a school answers to a different set of rules. Where someone expects to arrive months after the principal, put the dates in the same table, since arrival sequencing changes which documents must still be valid and when.
Review that table again whenever a start date moves. Dependants' documents are often issued with validity tied to the principal's, so a delay of a few weeks can quietly turn a settled plan into a set of renewals nobody has scheduled.
