Source of Funds Is an Audit, Not a Letter. Build the Paper Trail Before You Wire.

In finance, nobody accepts a number without a source document. USCIS approaches an EB-5 investor's capital the same way. The petition must show that the investment, and the fees paid alongside it, came from a lawful source through lawful means. 8 U.S.C. 1153(b)(5)(L); 8 CFR 204.6(j)(3). A one-page letter from an accountant stating that the investor is wealthy does not meet that standard, and it never has.

The useful way to think about source of funds is as two separate exercises that must reconcile: where the money was earned, and how it traveled.

Part one: where the money came from

Every dollar of the investment traces to one or more original sources. The common ones, and what typically documents them:

Salary and business income. Employment contracts, payroll records, and personal tax returns for the years in which the savings accumulated. For business owners, corporate financial statements, corporate tax filings, and records of distributions or dividends paid to the investor.

Sale of real estate. The acquisition deed and how the purchase was funded, the sale contract, the closing statement, proof of taxes paid on the gain, and the bank record showing proceeds received.

Sale of a business or shares. The purchase agreement, valuation or pricing support, proof of the investor's original ownership, and the receipt of proceeds.

Gifts. Gifted funds count only if they were given "in good faith" and not to circumvent the rules on permissible capital. 8 U.S.C. 1153(b)(5)(L)(iii)(I). In practice, the donor must document their own lawful source with the same rigor as the investor, along with the gift instrument and proof of transfer. A gift simply moves the audit one generation up.

Loans. Loaned funds are subject to the same good-faith requirement. Loan proceeds can qualify as the investor's cash, a position confirmed in Zhang v. USCIS, No. 19-5021 (D.C. Cir. Oct. 27, 2020). The loan agreement, the lender's identity, collateral documentation, and the investor's personal liability for repayment all need to be in the file.

A recurring issue is the gap year. An investor with strong income in recent years but a large balance that predates those years must explain the earlier accumulation. Old records are often the hardest to obtain, which is why this work should begin months before the investment, not the week of filing.

Part two: how the money moved

The path of funds is a chain of custody. It must show each transfer from the original source account to the new commercial enterprise or its escrow, with no gaps.

A clean path typically includes:

1. The account where funds were first received from the lawful source.
2. Every intermediate account, including accounts held by family members or holding companies.
3. Currency exchange records, including the exchange rate and the institution that performed it.
4. The outbound international wire confirmation.
5. The inbound receipt at escrow or the enterprise.

Two issues come up constantly in practice.

Cash deposits and consolidation. When funds were combined from several sources into one account before being wired, each inflow must be tied back to its origin. An unexplained cash deposit in the middle of the chain is the single most common finding.

Capital controls and third-party exchangers. In some countries, moving large sums abroad requires licensed channels or regulatory approval. Where an investor has used an informal exchanger or a third party to move funds, the path of funds becomes difficult to document and can raise concerns about whether the transfer complied with local law. This should be discussed with counsel before any money moves.

Build the file like a reconciliation

The approach we recommend mirrors a year-end close:

• Start with a schedule. List every source, amount, date, currency, and account on a single ledger. Total it and tie it to the investment amount plus fees.
• Attach a document to every line. No line without a source document.
• Translate and certify. Foreign language documents need certified English translations.
• Reconcile balances. Opening balance plus documented inflows, less documented outflows, should equal the balance transferred. Variances must be explained.
• Keep the fees in scope. The administrative fee paid to a regional center and legal fees also need a lawful source.
• Preserve originals. Keep full bank statements, not screenshots or selected pages. Adjudicators notice when pages are missing.

Timing matters

Source of funds evidence should be assembled before the funds are transferred, not after. Once money has moved through an undocumented account, the gap is permanent. An investor who is two months from investing and has not started this exercise is not two months from investing.

The proposed rule DHS published on July 2, 2026 would add more detailed documentation standards for lawful source. 91 FR 40676. It remains a proposal, but the direction is clear: expect more scrutiny of this part of the petition, not less.
