No. Qualifying L spouses may work incident to valid status with appropriate evidence; children lack that benefit solely as dependents.
Use individual status evidence
The employer’s need for help does not grant relatives permission. Describe actual household activities separately. The dependent category is for a qualifying spouse or unmarried child under 21; each person needs valid status.
Build a dated review file around each family member's status record, relationship proof, age, education plan, and any separate employment arrangement. Make a chart showing passport validity, marriage or birth records, current status, planned travel dates, and each child’s age. Place the principal’s status end date beside the family calendar: L-1A has a general seven-year maximum, subject to regulatory exceptions and recapture rules. Spousal employment authorization is documented, and that documentation has its own issuance timeline; a spouse counting on income from a fixed date should know when the underlying evidence can realistically exist. Marriage must be legally recognized for the spouse to hold derivative status at all, which is worth confirming for couples who have lived together for years without marrying.
