Retrieve whatever exists in writing: the application copy or confirmation, the refusal notice, the date and category, passport pages from that period, and any correspondence from a former representative. If nothing was kept, say so plainly rather than reconstructing details from memory, and ask counsel how to proceed.
Written proof beats a remembered version
Prepare an inventory distinguishing records held, records requested and recollections that cannot yet be verified. Do not replace an unknown refusal ground with a guess. If a material document cannot be recovered, ask what alternative evidence and explanation are appropriate before filing. Cross-reference any facts shared with the investor’s application so the two accounts remain accurate.
Support each link with bank records, invoices, bills of sale, contributions, assignments, leases or existing corporate resolutions. Ask next for a plain list of conditions that remain outstanding, since a deal still subject to financing approval has not put anything irrevocably at stake. Each item in the second pile should be answered in writing by the seller or the issuing authority, because a consular officer will ask how the buyer will lawfully carry paying guests on day one.
A deposit the buyer can recover by walking away evidences an intention rather than an investment.
