The manager’s transfer does not automatically grant the household identical permissions. A qualifying spouse in valid L status may work incident to that status with appropriate evidence; a dependent child does not gain that work benefit.
Check what the relocation company has actually arranged
A relocation package may book travel, retrieve civil documents or reserve housing without completing anyone’s immigration process. Ask which tasks have been performed and which status records are still needed for each person. L dependents must be a qualifying spouse or unmarried child under 21. If the manager travels first, preserve the records needed for the later family application rather than assuming the shipping or travel provider has resolved it. A paid relocation invoice is not an admission document.
The spouse's position is comparatively clear: once in L-2 status, employment is permitted without a separate application for authorization, although the spouse should carry the documentation that evidences that status and should confirm what a particular employer will accept. The principal still needs a qualifying organization, an eligible year of foreign employment in the relevant three-year period, and a primarily managerial or executive role; L-1A time is generally capped at seven years.
