Not necessarily. The official FAQ's additional family terms are described for an accompanying spouse or an eligible unmarried child under 21. An adult child outside that description needs to be assessed against the actual current eligibility rules rather than assumed into the household total.
Check each family member's own eligibility before budgeting for them
List every person the household hopes to include and verify, individually, whether the current official terms actually cover that person. As checked September 7, 2026, the stated additional amount per eligible family member is a US$15,000 processing fee and a US$1 million gift. Do not assume every household member qualifies on the same basis, and do not assume a payment protects anyone's age or eligibility going forward.
Make a person-by-person family table before calculating commitments. A spouse and unmarried children under 21 should be included on the principal's initial application; each family member is subject to a separate nonrefundable US$15,000 DHS processing fee and a separate US$1 million gift. An adult child cannot simply be relabeled as a dependent. Record birth dates, marital status, passports, relationship documents, admissibility issues, and who genuinely plans to immigrate. First submit the online filing and each required nonrefundable US$15,000 DHS fee; after settlement comes the USCIS prompt for Form I-140G, followed by vetting and only then each requested US$1 million gift. The common mistake is paying for a relative before confirming the published family definition covers that person.
Hypothetical example: a Windsor architectural-practice owner wants to include her husband, a 19-year-old unmarried daughter, and a 22-year-old son. She gathers civil records and has each person's eligibility assessed under current instructions, recognizing the older son is not automatically included. The family compares travel and education plans without assuming payment preserves age. They re-verify official directions before anyone pays and keep the principal's EB-1 or EB-2 evidence separate from eligible-relationship proof.
