No. It may explain the payer relationship, but the current official framework governs the program obligations.
Use each document for its purpose
Identify discrepancies and unresolved terms rather than treating a commercial agreement as an immigration decision.
Each person's folder holds their own identity and civil documents, the official instructions as published on the day that person acted, their vetting correspondence, their own payment receipts, and a short list of the relatives they intend to bring. The review should separate identity and civil documents, underlying immigrant-category evidence, employer sponsorship terms, official notices, payment source records and confirmations. The first review should identify what a document proves: a passport establishes identity and nationality; a payment receipt may establish that a required amount was transmitted; achievement records may support an EB-1 or EB-2 theory. If the official instructions require identity, financial or background documents, gather those the same way you would for any immigrant petition: originals, certified translations where needed, and a clear explanation of the source of the gift funds. Keep the application and fee confirmations, the instructions received, everything submitted through the official portal, records of the gift when instructed, and any correspondence about maintenance or transfer, together with the internal approval that authorised the spending.
