TL;DR
USCIS requires a documented chain showing every dollar of the $800K traces to a lawful origin. The documentation set varies by source type (salary, business sale, inheritance, property, loan, gift, stocks) — but the rule is universal: paper-trail everything, in English, with certified translations where needed.
Source-of-funds (SOF) is the single largest piece of an EB-5 filing — often 200-500 pages. USCIS reviews both the **lawful origin** (where the money came from) and the **path of funds** (how it moved from the origin into the investor's hands and ultimately to the project escrow). RFEs almost always trace to an incomplete chain.
Plan SOF documentation 3-6 months before filing — sourcing certified translations and old bank statements from foreign institutions is slower than people expect, and gaps trigger RFEs.
Beyond coordinates SOF documentation alongside an EB-5 immigration attorney who has filed hundreds of I-526E petitions. We flag the RFE patterns specific to each source type — particularly the 2026 RFE trends around crypto, gift-chain documentation, and salary-accumulation timing.
