The existing case file and its receipt or notice numbers, proof of who signs for the company, the second employee's identity and eligibility evidence, and the payment records for the earlier US$15,000 fee and gift. Where a notice contradicts the company's own records, investigate the discrepancy rather than repeating it.
Signing authority and the paper trail behind it
Signature authority changes with resolutions, resignations and reorganisations, and a filing signed by someone who no longer holds it invites questions later. Keep the corporate resolution, the officer's title and the date together with the case file. On the employee side, follow the supporting-document instructions issued through the official portal rather than filing thin and planning to supplement; incomplete submissions can draw a request for evidence or a refusal.
Keep identity and family information and a dated copy of the official terms ready, but do not describe an EB-5-style lawful-source file as a published Gold Card requirement. An instruction to pay through an intermediary’s account, a request to send funds to a third party who will handle it, or a promise that a payment can be reversed if the application fails should all stop the process.
