Use it for planning while checking actual status and permissions for each person. A handover estimate does not establish an authorized stay.
Keep individual activities visible
Qualifying L spouses are employment authorized incident to status with appropriate documentation. Children do not gain work permission solely through L dependent status. Study does not extend authorized stay, so review school and employment commitments separately.
Work authorization for an L spouse arises incident to the appropriate status, on the required evidence. A handover estimate comes from operational planning, while an authorized stay comes from an admission record tied to an approved petition, and the two do not automatically expire on the same date. List each family member's individual authorized period separately, since a spouse, a child, and the principal can each carry a different expiration even when everyone arrived together. Request written confirmation from the employer or attorney of whichever date is earliest, and treat that date, not the projected handover length, as the actual planning deadline. Ask whether an extension filing needs to begin before the handover concludes, since a lapse in status is not automatically cured by the underlying assignment continuing informally. Keep a shared household calendar noting each person's expiration separately from work or school calendars tied to the assignment, so no single family member's document is overlooked while attention stays on the operational timeline.
