The official FAQ addresses a principal applicant with an eligible spouse and unmarried children under 21; other extended family members are not covered as dependents and would need their own separate basis.
Identify exactly who qualifies as an included dependent
Confirm which specific family members meet the official definition of an eligible spouse or child before including them in the budget or application, rather than assuming a broader family group can be included together. Each included eligible family member adds a US$15,000 nonrefundable processing fee and a US$1 million gift, including in corporate cases. Intended joining family should be included initially.
Identity and relationship documents for each person, evidence supporting the EB-1 or EB-2 category, proof of the source of the gift funds, and a dated copy of the official terms the family relied on. Make a per-person chart covering identity, relationship, age, current official program terms, separate immigration qualifications, vetting, and any required payment treatment. Nothing about the size, price or configuration of a private purchase changes who may be included or what each additional person entails; those terms come from the official instructions and must be confirmed there, since they may change.
