Two separate stacks. The project side: dated economic reports, budget amendments, invoices and draw requests tied to the counted categories. Your side: bank records, sale or gift documentation, and prescribed historical tax records where required. Incomplete evidence can trigger a request for evidence or a refusal.
Assemble each stack completely before filing
Do not file a thin record intending to supplement it later. Corporate evidence — subscription agreements, escrow terms, the operating agreement, board approvals of the budget change — can bear directly on eligibility, not only on the project's health. If a document exists in several versions, submit the executed one and explain the sequence. Where the record is genuinely unavailable, document the effort made to obtain it.
With a signed gift letter, proof of the relationship, and the parents' own records: quota transfer documents, livestock sale invoices, bank deposits and tax returns. For each funding component, record the event that created the money, the person or entity entitled to it, and the accounts through which it moved. For direct EB-5, the evidence must support ten permanent full-time qualifying positions; regional-center cases may use authorized economic methodology, but still require a defensible job analysis. Source-of-funds evidence should be assembled as a chain, not as a collection of account balances.
