Yes, the closure of a bank is not itself disqualifying. What matters is whether you can still prove a lawful source and a lawful path for the capital. Certified successor records, archived statements, tax filings and transfer confirmations can carry that burden. An unexplained material gap can prevent USCIS from finding that you met the evidentiary burden.
Proving the money when the paper trail changed hands
Work backwards from the capital you will invest to the event that created it, and show each hop. A wind-up or acquisition usually leaves a records custodian, and courts, regulators or the acquiring bank may hold statements you cannot. Corporate records — resolutions, ledgers, sale agreements — can be eligibility-relevant where the money came from a business. Exact criteria beyond these general points need current counsel review on your actual documents.
Prepare an investor-specific eligibility sheet covering lawful capital placed at risk, applicable amount and project location, job methodology, and management participation. The investor must document lawful source and path of funds, participate in management or policy formulation, and support ten full-time jobs for qualifying US workers. A first review should trace each dollar from its lawful origin through every account into the qualifying investment, while separately testing the job-creation evidence.
