The current official programme permits a spouse and unmarried children under twenty-one to apply with the principal when included in the initial application. Each family member currently requires a separate $15,000 DHS processing fee and $1 million gift. A grown child who is twenty-one or older is not included on that basis and needs an independent route. Recheck every person's eligibility and charge on the official page before paying.
Grown children arrange their own route
The current official programme says a spouse and unmarried children under twenty-one should be included with the principal in the initial application if they intend to join the cardholder. Each currently carries a separate processing fee and gift, so a parent's payment does not automatically cover the household. An adult son or daughter who is twenty-one or older is outside that family definition and needs an independent immigration basis.
Review the family one person at a time against the official FAQ, including age, marital status, intended timing and the current charge. Perform that review again immediately before money moves because programme terms can change. Hypothetical example: a nuclear-medicine researcher plans to apply while supporting a spouse and a twenty-year-old unmarried child.
The first review produces separate identity and relationship records for every family member and a calendar for the child's age and travel plans. Birth and marriage certificates settle the relationship; each person's passport and immigration history settles their individual processing needs. The applicant should decide before payment whether the family will pursue the process together or whether a time-sensitive child needs separate advice.
Confusion follows when the principal's qualifications are treated as proof that every relative automatically receives the same outcome.
