Ask for the purchase agreement with its asset schedule, the lease or assignment, licence transfers, and any supplier or employment arrangements that continue. For a going concern, add historical financial statements, tax filings and customer contracts. Separately, gather your own proof of the lawful source and path of the invested funds.
Collect what proves the business can run
Bank records and a wire trail show that money moved; they do not show that a business exists. Pair them with the closing statement, insurance binder, licence confirmations, supplier quotations and signed leases. Where a document is still pending, record who is responsible and when it is expected rather than leaving a silent gap. Obtain required funding records during preparation; if unavailable, assess acceptable alternatives and filing readiness rather than assuming a later supplement.
Use real agreements and transfer records, and assess financing under the applicable E-2 rules without importing unrelated EB-5 assumptions. Do not silently change a lease into a purchase in the immigration account to increase the apparent investment. The escrow is then funded, which is the moment the funds become at risk, and the buyer's bank records from origin to escrow are gathered at the same time.
