The procedural anchor for an RFE is 8 C.F.R. § 103.2(b)(8), which authorizes USCIS to request additional evidence and to set a response window. The same regulatory section authorizes a Notice of Intent to Deny (NOID), which is the more adverse cousin: USCIS has tentatively concluded the petition should be denied and is giving the petitioner a final chance to rebut. In either posture, the response date stated in the notice controls, so reading the notice carefully on day one is essential.
The substantive standard remains preponderance of the evidence: more likely than not. That standard has not changed. What has changed is USCIS's willingness to extend benefit of the doubt. Officers are applying 8 C.F.R. § 103.2(b) ("approvable when filed") more aggressively, treating gaps that previously would have been cured at the RFE stage as grounds for outright denial of the petition. Petitions filed in the 2018-2019 era when "skeletal" filings cured at RFE were workable are not the petitions filed now.
For source-of-funds RFEs specifically, the federal courts in Battineni v. Mayorkas, Civ. No. 22-1332 (PLF) (D.D.C. Oct. 2, 2024) and Zhou v. Noem, Civ. No. 19-2650 (TJK) (D.D.C. Feb. 6, 2025) have narrowed USCIS's reach: investors generally need not trace beyond their own immediate source, and prior owners of gifted funds are not required to be sourced as if they were the petitioner. Those rulings are persuasive but are not binding on adjudicators outside the parties to the cases. Practitioners typically include the Battineni / Zhou legal argument where it fits the facts but do not rely on it as a substitute for documentation. Whether a particular RFE response is sufficient depends on the entire record and the discretion of the adjudicating officer.
The substantive RFE patterns that we and other firms see most often on I-526E petitions are: insufficient accumulation evidence on source of funds; breaks in the path of funds; loan-structure scrutiny (especially non-bank lenders, where the lender's own seven years of tax returns and two years of bank statements are now expected); conditional-gift language; cross-reference inconsistencies (DS-160, DS-260, prior NIV filings, social media, news coverage); and partial-investment timing issues. On I-829 petitions, the dominant pattern is de novo re-examination of source of funds, sometimes reaching back ten or more years, despite no regulatory authority for that approach. Each pattern calls for different documentary remediation, and the right approach is decided case-by-case.
