No. Identify intended eligible joining family in the initial application as directed by the FAQ, and clarify their separate US$1 million gift and US$15,000 fee per person. These family amounts also apply in corporate cases; confirm individual eligibility and operative instructions.
Make the benefit scope explicit
The eligible spouse and unmarried children under 21 require individual assessment. A benefits summary mentioning family does not itself resolve payment responsibility or grant status.
Each included family member is currently subject to a separate processing fee and gift, and a successful family member receives the privileges of lawful permanent residence, including employment authorization. Record every intended relative by name, relationship and date of birth at the outset and watch the ages, because a child who reaches twenty-one before the relevant point can lose derivative eligibility while the rest of the household proceeds. Identity and civil records, immigration and travel history, the material supporting the eligibility theory, and each family member's own records are four different groups answering four different questions. Ask counsel which family member's documents are most likely to generate a request, since a single missing item for one child can hold the entire case, and that person's records are worth checking first rather than last.
