Record the actual situation and follow the applicable official process for the request. Do not invent a record or describe an application for it as the completed document.
Keep the response truthful
A clear account of the missing evidence is different from pretending the requirement has been fulfilled.
Gather identity and family documentation and a clear statement of the specific circumstances involved, then check them against the current official instructions rather than an informally described version of the requirements. A dated copy of the official program page and any implementing executive action, the intermediary's written material and contract, and a complete record of any payment including payee, instrument and date. Create a dated program dossier containing the official instructions actually relied upon, identity and civil records, payer authorization, source evidence, transfer directions, and receipt. The official USCIS instructions govern the supporting documents required in the case; these preparatory records help explain the actual funding arrangement rather than constitute a universal mandatory checklist. The applicant is named on the application; the payer is named on the payment record; the qualifying relatives are named by the relationship evidence — birth or marriage records showing the connection the published terms require.
