An internal benefits summary is not the spouse’s immigration record. A qualifying L spouse may work incident to valid qualifying status with appropriate evidence; children do not gain that benefit solely as dependents.
Check the individual status evidence
Review the spouse’s actual admission and planned activity. Company relocation benefits and U.S. work authorization serve different purposes. The dependent framework generally covers a spouse and unmarried children under 21; each person must obtain and maintain the appropriate status.
Passports for every travelling family member, the marriage certificate, birth certificates for each child, the principal's petition and approval evidence, and any previous US immigration records. For a spouse considering employment, confirm the current evidence an employer will need for onboarding and keep that question separate from the principal’s corporate transfer documentation. 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. A larger role does not widen a dependant's permissions, and a household that plans around the promotion rather than around each person's status tends to discover the gap only after arrival.
