No. Each person’s status and activity require assessment. Qualifying L spouses may be employment-authorized incident to status with appropriate evidence; children do not gain work permission solely as dependents.
Keep family assistance out of staffing assumptions
Do not count a relative as available operational support without considering their actual role and permission. Family relationships do not themselves establish employment authorization.
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. Confirm the spouse's current status evidence rather than assuming a document is automatically issued, and track a child's school plans and any age-related deadlines separately from the principal applicant's own timeline. Where a spouse intends to work, the authorisation is generally incident to valid dependent status and is evidenced by that spouse's own record, so it can only be as reliable as the document behind it. Children sit differently again, and a child approaching the upper age limit for dependent status deserves that checked against the calendar early rather than discovered late.
