The U.S. Treasury has issued new guidance on U.S. banking red flags, urging financial institutions to watch for suspicious activity linked to immigration status and illegal hiring schemes. The move comes through the Financial Crimes Enforcement Network, known as FinCEN, which works to detect and prevent financial crime in the United States.
The advisory tells banks to be alert for identity theft, payroll tax fraud, and money laundering patterns. Officials say these risks may be linked to companies hiring workers without legal authorization to work in the country. Banks are being asked to closely monitor account activity that could indicate illegal financial behaviour.
The guidance follows a recent executive order signed by President Donald Trump in May. The order calls for stronger checks on financial activity that may be linked to immigration status. It instructs regulators and government agencies to look for signs that individuals without legal status may be opening bank accounts or applying for credit.
However, the order is less strict than earlier expectations. Early reports suggested that banks might be required to collect citizenship or immigration status from all customers. That requirement was not included. Instead, the focus is on increased monitoring and improved detection of risk patterns.
Officials say the goal is to reduce misuse of the financial system. Treasury Secretary Scott Bessent said the administration will not allow illegal immigration-linked schemes to take advantage of banks or harm taxpayers. He added that some payroll systems may rely on access to U.S. banking services to process payments for unauthorized workers.
Banks have traditionally not collected citizenship or immigration data from customers. Because of this, there are no clear public figures on how many accounts may be linked to immigration status issues. Financial institutions rely instead on general anti-fraud and anti-money laundering systems to detect risk.
The banking industry had pushed back against earlier proposals that would have required collecting citizenship information. Banks argued that such rules would increase costs and create heavy administrative work. They also warned it could slow down account opening and loan approvals for many customers.
In response to industry concerns, the final version of the policy focuses on guidance rather than strict requirements. Banks are not being ordered to collect citizenship data. Instead, they are being advised to strengthen monitoring systems and report suspicious patterns linked to financial crime.
The advisory outlines more than a dozen potential warning signs, often called “red flags.” These include unusual payroll activity, mismatched identity information, and transactions that suggest fraud or hidden employment arrangements. Banks are expected to use these indicators as part of their existing compliance systems.
Financial experts say the move reflects a broader effort by U.S. authorities to tighten oversight of financial systems connected to immigration enforcement. They also note that banks will need to balance compliance rules with customer privacy and operational efficiency.
Authorities say they will continue working with banks to improve detection tools and reduce financial crime risks. The advisory is part of ongoing efforts to strengthen oversight of the banking sector while addressing concerns linked to illegal employment networks.
