That has to be answered explicitly, in writing, before you rely on it. Each joining spouse and each unmarried child under 21 adds US$15,000 and a US$1 million gift, and the offer may or may not cover them. Company profits on paper are not the same thing as personal liquidity.
Allocating the family gifts before the offer is accepted
Ask the sponsor to state, per person, who pays the fee, who makes the gift, and whether any part of it is recoverable from you. Official instructions recommend including family from the outset for program benefits, which is a reason to settle this early rather than after vetting. An account labelled for administrative purposes does not by itself make funds qualify; what the money actually is and how it is used govern.
Each joining family member carries a separate processing fee and gift under the published terms and should be named in the initial application. Ask how the timing of family inclusion affects the process and each person’s eligibility. Eligible children generally are unmarried and under 21, with individual CSPA review, and a family member’s case still needs the applicable supporting evidence.
