No. Review the actual agreement and current official family terms for each proposed accompanying person. Current official terms add a US$15,000 processing fee and US$1,000,000 gift for each eligible joining spouse or unmarried child under 21, including corporate cases; confirm individual eligibility and the operative instructions.
Build the individual record
Identify relationships, ages and intended inclusion. A principal sponsorship proposal does not by itself establish family eligibility, costs or status.
Because the described route runs through existing employment-based immigrant categories, those categories' own requirements govern eligibility, and a payment does not create eligibility a person does not otherwise have. Give each household member a folder and a short list: identity document, relationship evidence, and any name-change or prior-marriage record needed to make the relationship legible. The identity of the sponsor and the named family members affect the stated payments, while government eligibility conditions remain independently applicable. The practical decision is whether to include that person at the initial stage or use another available process later; do not let a shared address obscure separate eligibility and document requirements.
