Understanding EB-5
Source of Funds
USCIS doesn't just verify you have $800,000 — they verify exactly where every dollar came from. This guide shows you how to build an airtight SOF documentation trail before you wire a single dollar.

USCIS
I-526E reviewed
EB-5 source of funds (SOF) documentation must prove three things to USCIS: that your capital was lawfully earned, that the documented amount is sufficient ($800K or $1.05M), and that every dollar can be traced from its origin through your bank account to the EB-5 escrow wire. Missing any link in this chain results in an RFE or petition denial.
What USCIS Actually Verifies
The 3 SOF Tests You Must Pass
Pass all three or your I-526E petition fails — partial documentation is not accepted.
Lawfulness
Was the money legally earned?
Funds must originate from legal activity — salary, business income, real estate, gifts from documented sources, or properly structured loans.
Sufficiency
Is the documented amount enough?
You must show enough lawfully sourced capital — at minimum $800,000 (TEA) or $1,050,000 (standard) — fully accounted for from source to escrow.
Path of Funds
Can every transfer be traced?
USCIS requires a complete, unbroken chain — every movement of money from earning through banking to the escrow wire must be documented.

Your Preparation Roadmap
The 90-Day SOF Preparation Plan
Start building your SOF package 90 days before filing. This timeline prevents last-minute gaps.
The SOF Standard USCIS Expects
Your SOF documentation must be so thorough that a USCIS officer can reconstruct the complete history of your investment funds independently — without asking you a single question. Build that file first. File the petition second.
