Proof of treaty nationality, evidence of the source and path of the funds, the purchase agreement and financing documents, evidence that the money has been irrevocably committed, and records showing the enterprise is real, operating and not marginal.
A path, not a balance
A bank statement showing a large balance answers almost nothing. What persuades is a continuous trail: where the money originated, how it moved, and where it ended. For Fatima that means records of the log-trucking business's earnings or the sale of equipment, tax filings consistent with those earnings, transfers between named accounts, and the closing statement showing funds released to the seller or into the business.
Alongside the trail sit the commercial documents, including the signed purchase agreement, the note in its final form, any escrow instructions, leases, and the operating authority and insurance the business will hold. Evidence of non-marginality comes from the seller's history rather than from optimism, so filed statements, payroll registers and customer contracts are worth more than a business plan on their own.
