The actual ownership and funding arrangement need review, while charges and eligibility apply to each included person.
Build the applicant-specific budget
Each eligible joining spouse or unmarried child under 21 adds US$1 million and US$15,000, including corporate cases. Shared wealth does not waive individual requirements.
Assess eligibility for the immigrant category that would follow before considering payment, confirm each family member's inclusion, then verify the current official terms on a recorded date. 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. Beyond money, each family member is assessed for admissibility on their own record, and children are subject to the age-21 rule, with the Child Status Protection Act applying only as the law provides for the underlying category. 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. 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.
