No. Each actual applicant remains subject to the applicable government conditions. A shared payer or proposal does not merge the eligibility decisions.
Keep the people behind the budget identifiable
The government determines classification, admissibility and visa availability for the real cases. Do not present one favourable result as a guarantee for the rest of the group.
The official Gold Card page presents a sequence of application and processing fee, vetting, further instructions and gift, followed by permanent residence through an existing employment-based category as determined by the authorities and subject to visa availability. Start with the current official program terms and write down which facts the applicant must supply, which screening stage remains, and which eligibility pathway is actually described. Money moves one way here, from the applicant to the U.S. government, and it confers no classification and cures no ground of inadmissibility, so a company signing off the spend is paying for a process rather than for an outcome. The published requirements do not turn on a residential address: the applicant must be eligible for lawful permanent residence, admissible, complete the application and fee, pass vetting, make the gift when instructed, and receive an EB-1 or EB-2 determination subject to visa availability. The official material describes reusing a corporate gift for a new sponsored employee subject to a transfer mechanism, a stated fee, and fresh screening, so counsel should verify the current conditions for both individuals.
