No. Only your spouse and unmarried children under 21 can be derivatives. An adult daughter and her children have their own status, and their future sponsorship would be a separate family-based process after you become a permanent resident.
Derivatives are defined by age, not by why you are moving
Hypothetical example: a Rothesay retiree's reason for EB-5 is to live near his daughter, who became a U.S. permanent resident through marriage, and her two young children, who are U.S. citizens.
His petition can include his wife as a derivative spouse. It cannot include the daughter, who is an adult, or the grandchildren, who are not his children. Their statuses are already independent of his.
Once he and his wife become permanent residents, sponsoring an adult married daughter is not available to permanent residents at all, and family-based categories for other relatives carry their own limits and waits. The reviewer should set out realistically what EB-5 achieves for the household: permanent residence for the couple, the ability to live in the same city as the daughter and nothing automatic for anyone else. Planning on that basis avoids disappointment later.
