For investors seeking their US green card via the EB5 Immigrant Investor Program, navigating and fulfilling the thorough documentation requirements can seem overwhelming. Two critical—and often misunderstood—components of the EB5 process are the source of funds (SoF) exercise and the background verification process, also known as the KYC/AML (Know Your Customer/Anti-Money Laundering) review. While both steps involve providing financial and identity documentation, they serve very different purposes, are reviewed by different stakeholders, and require different levels of detail.Â
Understanding the distinction between these two processes is essential to successfully preparing your EB5 petition and complying with both immigration and financial regulations.Â

What Is the EB5 Source of Funds (SoF) Exercise?Â
The source of funds exercise is a mandatory part of the EB5 petition (Form I-526E) submitted to US Citizenship and Immigration Services (USCIS). The purpose is to demonstrate that your EB5 investment capital was obtained through lawful means and that the path of funds from origin to deployment can be fully documented.Â
This process is extensive and detailed. It involves tracing the entire history of how you earned or acquired the capital you plan to invest—whether through salary savings, sale of property, business income, loans, gifts, or inheritance. Each step must be backed by credible documentation such as:
- Bank statements
- Tax returns
- Employment or business records
- Sale or transfer agreements
- Gift affidavits
- Loan agreements and collateral documentation
The SoF exercise is evaluated by USCIS officers to ensure compliance with US immigration laws. Failing to adequately document the lawful source and clear path of funds can result in delays or denials of your EB5 petition, making it a crucial component of your application. Â

What Is KYC/AML?
KYC (Know Your Customer) and AML (Anti-Money Laundering) checks are financial compliance procedures conducted by regional centers, fund managers, or financial institutions to comply with international banking and anti-money laundering laws. These checks are typically performed before accepting your investment into an EB5 fund.Â
The goals of a KYC/AML review are to:
- Confirm your identity (using a passport or national ID)
- Assess your risk profile as an investor
- Screen for involvement in illicit financial activity or other sanctioned activity
- Comply with US and international anti-money laundering regulations
The KYC/AML process may involve third-party background checks and global watchlist screenings. However, it does not require the same level of documentation or financial tracing as the USCIS source of funds process. Instead, KYC/AML focuses on ensuring that the investor is not a politically exposed person (PEP), on a sanctions list, or associated with suspicious financial activity.

Final Thoughts
For EB5 investors, understanding the difference between SoF and KYC/AML isn’t just a technical detail—it’s a fundamental part of a successful immigration and investment strategy. Knowing what’s required, why it matters, and how to prepare will give you a stronger foundation for your EB5 journey and a smoother path toward achieving permanent residency in the United States.Â
Work with experienced EB5 professionals, including attorneys and regional centers, to help you navigate both processes efficiently and reduce the risk of delays or errors. With the right guidance and preparation, each step of the process brings you closer to building a new life in the United States—and turning your dream of US residency into reality.Â
