Bring the citizenship certificate, any receipt or confirmation for the pending passport application, and previous travel documents including expired ones. Add records showing your legal name history. For the business side, bring source and path of funds evidence; a current account balance alone does not show where the capital came from.
Build the identity file and the funds file in parallel
Treat identity and money as two evidence tracks. On the identity side, collect documents that connect each version of your name and each prior travel document to the same person. On the funds side, trace the money from its lawful origin through each account into the enterprise, keeping transfers, sale proceeds, gift or loan documentation, and any collateral terms. Loans are not prohibited; what secures them can matter to whether capital is genuinely at risk.
Some records take weeks: archived bank statements, carrier itineraries, corporate documents held by the seller. Include an intelligible account of the operative stages and supporting transaction evidence. Gather the agreements that establish the applicant's actual ability to develop and direct the business, including any rights retained by a seller, co-investor or lender. The review normally produces a source-and-path schedule, bank records, contracts, invoices, ownership documents and a practical operating plan.
