No. Each eligible joining spouse has a stated US$15,000 nonrefundable processing fee and US$1 million gift. The same amounts apply to each eligible joining unmarried child under 21.

These family charges apply in corporate cases too, and initial inclusion is recommended. A larger pooled budget does not waive individual eligibility or automatically protect age.
The employment-based immigrant categories include a spouse and unmarried children under twenty-one as derivatives, and it is natural to expect the same pattern elsewhere, but that expectation is an assumption rather than a finding. The official program’s current rules control the role of an applicant, any sponsor, and any family member; a private employer cannot convert a relative into an eligible person by paying or promising support. Build a child-specific chronology before payment: long-form birth record, passports, custody or adoption evidence where relevant, marital-status records, prior filings, and exact dates needed for any CSPA review. Where a household's plan depends on a particular treatment of a child approaching adulthood, obtain written confirmation before committing funds, since a transfer of this kind cannot be reversed once the answer turns out to be different from the assumption.
