Do not infer immigration effects from the internal promotion date alone. Have the principal’s transition and each family member’s actual status assessed. Nothing in the household changes on the date the company announces. The employer’s petition governs the principal’s classification, and each dependent’s permission follows from documents issued to that person, not from the promotion memo. Ask which document in the family’s file would need to be reissued, who issues it, and what has to happen at the company before that request can even be made.
Check documents and activities individually
Qualifying L spouses are authorized to work incident to status with appropriate documentation. Children gain no work permission solely through L dependent status. An employer’s announcement does not replace the individual documents governing stay and work.
Take the dependents’ questions in the order the answers become available. Whether the principal’s classification changes is decided first, because a spouse’s work authorization and the children’s permitted activities are both incident to the status the principal holds. Only once the principal’s position is settled is it worth applying for or renewing anything on the dependent side.
A spouse who is working should confirm what documentation supports that work under the classification actually held before any lapse, rather than after. Children hold no work permission through L dependent status at any age, so a student placement offered through a school is a question about the placement’s terms and the status held, not one the promotion resolves.
