Each joining spouse and unmarried child under 21 adds a US$15,000 processing fee and a US$1,000,000 gift under the current FAQ, and they should be included in the initial application.
Every joining family member carries the full amounts
The current official terms do not offer a discounted family rate. A spouse and each unmarried child under 21 who joins the application pays the same nonrefundable processing fee as the principal and makes the same US$1,000,000 gift after successful vetting, and the FAQ directs that they be included in the initial application to obtain the associated benefits. For a family of four the household commitment is four fees and four gifts. A child who turns 21 or marries before the case concludes may lose eligibility as a joining family member; the current instructions should be checked for how age is measured, and the family should not assume the protections that apply to petition-based immigrant categories carry over. Once permanent residence is granted, a spouse and children may work and study without restriction.
Family eligibility must be confirmed from the current official framework rather than assumed from a spouse's or parent's application. A payment made by one applicant to the U.S. government does not automatically make an adult relative eligible, and family members may have separate vetting or payment requirements. Hypothetical example: a theatre producer wants to include a spouse, a 20-year-old child, and a 24-year-old child. Before transferring funds, the family should identify which people are applicants under the published terms and which person must make each required payment.
