Documenting source of funds means showing USCIS where each dollar of the $800,000 or $1,050,000 was lawfully earned, then tracing an unbroken path from that earning event into the new commercial enterprise. Two things get tested: the origin of the wealth and the route the specific dollars traveled. Officers do not accept a narrative. They want incorporation records, tax filings, the sale contract, the bank statement showing proceeds arriving, and a statement for every account the money passed through afterward.
What lawful source means to the officer reading your file
The standard of proof is preponderance of the evidence, meaning more likely than not. That sounds forgiving. In practice an adjudicator who cannot follow the money from one account to the next issues a Request for Evidence rather than guessing, and every gap is read against the petitioner.
Two separate questions live inside every source of funds file. Where did the wealth come from, and was earning it lawful under the law of the country where it happened? Then: how did the exact dollars now sitting in escrow get there? An investor who sold a factory in 2019 for the equivalent of $3 million has answered the first question and none of the second.
The evidence 8 U.S.C. 1153(b)(5)(L) actually asks for
Anyone filing today works from the statute rather than the old regulation. The EB-5 Reform and Integrity Act of 2022 wrote a source of funds list into 8 U.S.C. 1153(b)(5)(L), binding on every petition filed on or after 14 May 2022, and it runs to five items:
- Foreign business registration records, plus the tax returns of any company or partnership you held.
- Personal tax returns of any kind, filed during the past seven years with any taxing jurisdiction inside or outside the United States, by you or on your behalf.
- Any other evidence identifying another source of the capital, or of the administrative fees.
- Certified copies of judgments, plus evidence of pending governmental civil or criminal actions, governmental administrative proceedings and private civil actions involving possible monetary judgments against you, from any court anywhere.
- The identity of every person who moved money into the United States on your behalf.
Two of those catch people out. Seven years is longer than the five that the older regulation at 8 CFR 204.6(j)(3) asked for, and the count runs on returns you filed rather than on years you earned. The judgments item now carries no time limit at all, where the regulation stopped at fifteen years, so a commercial dispute you consider trivial belongs in the file with an explanation rather than left out and discovered later.
The Act widened the duty in a second direction. Administrative fees paid to a regional center now require the same lawful source proof as the capital itself, so the wire that paid the fee gets traced too. USCIS sets out how it reads all of this in volume 6, part G of the USCIS Policy Manual.
Trace the money one account at a time
Build the file as a chain. Each link needs the sending account statement showing the debit and the receiving account statement showing the credit, with dates and amounts that match to the dollar.
Where a currency conversion happened, include the bank record and the rate applied on that date. Where the amount shrank between accounts because fees came out, explain it in the cover letter before the officer has to notice it. Where a relative's account served as a waypoint, that person is now part of the file and needs documenting.
Different origins carry different burdens. Salary accumulated over fifteen years means employment contracts and annual returns, plus an explanation of how someone earning that documented salary ended up with that balance. A property sale needs the title record, the sale contract and the tax paid on the gain. Business profits need financial statements and distributions that reconcile to the corporate filings.
Gifts and loans: whose capital is it?
A gift is permitted and it is common. The catch is that the donor's own source of funds becomes part of your petition, documented to the same depth, and the statute wants the gift made in good faith rather than as a way around the source of funds rules. A side arrangement to return the money once the green card issues turns the gift into something else and puts the whole petition at risk.
Loans moved in the investor's favor. Litigation in Zhang v. USCIS established that the proceeds of a bona fide loan count as the investor's own cash, and USCIS revised its policy to match, so collateral no longer has to be the investor's personal assets in every structure. You still need the loan agreement and evidence that the lender had the money to lend. Proof that the debt is real rather than decorative matters just as much. Our page on gifted and loaned funds in EB-5 works through the documents each structure needs.
Currency controls and money that moves in tranches
China caps individual foreign exchange at the equivalent of $50,000 per person per year, which is why capital often crosses the border in tranches carried by relatives and friends. USCIS knows the practice well, and naming those people is not a courtesy: the identity of everyone who carried money for you sits on the statutory evidence list. For every conduit the officer expects identification, the relationship to you, account statements showing the money in and out, and a declaration that the funds were never theirs. Our page on source of funds for Chinese investors covers the mechanics in depth.
India and Vietnam impose controls of their own. One principle holds everywhere: the officer needs to see that the person whose name sat on the transfer was moving your money rather than their own.
Present the file so an officer can follow it
Write a source of funds memorandum that tells the story in chronological order and cites exhibit numbers, then place the exhibits behind numbered tabs in exactly that sequence. An entry reads something like this: proceeds of a 2018 sale of a stake in a trading company deposited to the seller's account on 12 March (Exhibit 3.1), converted to dollars on 9 April at the rate shown (Exhibit 3.4), wired to the escrow agent on 2 May (Exhibit 3.7).
Every foreign language document needs a certified translation. Summaries do not count.
Keep the petition consistent with what you have filed elsewhere. Tax residency positions taken under the IRS rules on determining tax residency status, and the accounts you will later disclose under the FinCEN foreign bank account reporting rules, should not contradict the picture your petition paints. Investors sometimes discover late that their EB-5 file and their tax file tell different stories about the same company.
Which patterns reliably draw an RFE?
- Cash deposits with no documented origin, especially round numbers landing shortly before the wire out.
- A gap of several months between one account closing and the next opening, with nothing in between.
- Business income claimed without matching tax returns, in a country where returns were required.
- A gift from a donor whose own wealth gets described in a single paragraph.
- Funds routed through a third country with no explanation of why they went there.
None of these is fatal on its own. All of them cost time, and time in EB-5 is measured against a priority date and a visa queue. Our page on I-526 outcomes and next steps covers what happens when the RFE arrives anyway.
One deadline that should shape your schedule
Petitions filed on or before 30 September 2026 are protected by 8 U.S.C. 1153(b)(5)(S), titled Protection from expired legislation, which keeps them moving through adjudication even if the regional center program lapses; the program itself is authorized through 30 September 2027. A source of funds file takes months to assemble, and a family reconstructing fifteen years of records across two countries should count backward from that date. Thresholds also see their first inflation adjustment on 1 January 2027.
