No such completion should be assumed. Identify the actual separate process, instructions and charges for any temporary-status action.
Keep payment purposes visible
Gold Card currently requires US$15,000 nonrefundable processing and the applicable post-vetting gift. Do not record that transaction as payment for a different immigration request or assume it remedies an omitted temporary filing. Payments are easiest to keep straight when each one is recorded against the process it belongs to, the date it was made and what it was for.
A payment made under the published Gold Card terms is made by the applicant to the U.S. government under those terms; a filing fee for a temporary-status request is a separate charge under separate instructions, and neither discharges the other. What goes wrong is a household ledger showing a large total and an assumption that everything immigration-related has therefore been dealt with.
Keep the ledger itemised by process. Before relying on any amount, confirm it against current official figures rather than a number recorded earlier, and note that a payment receipt evidences payment only: it does not evidence eligibility, does not evidence status, and does not evidence that a required filing was made. Where a company is paying part of the cost, record which entity paid what, since that question surfaces later in ways that are hard to reconstruct.
