Treasury pushes banks to flag customers suspected of lacking legal status

Treasury has begun pressing banks to look for signs that customers may lack legal immigration status, a move that pulls financial institutions deeper into President Donald Trump’s immigration crackdown without ordering them to cut off undocumented customers outright. The guidance expands information sharing and could force banks to change how they open accounts, screen risk and file suspicious-activity reports.

The shift follows Trump’s May 19, 2026 executive order, “Restoring Integrity to America’s Financial System,” which directed Treasury, the Consumer Financial Protection Bureau and banking regulators to issue guidance and propose changes aimed at strengthening customer identification and due diligence. The White House said the order was designed to protect the financial system from illicit activity and address the credit risks of extending services to non-work-authorized immigrants.

Treasury’s June 12 guidance said banks may share information more quickly about suspected customers and should look for signs that a customer may lack legal status. The department framed the move as a response to fraud and crime, not as an explicit prohibition on undocumented customers. Still, the practical effect could be broad: account opening reviews, internal risk screening and suspicious-activity reporting may all come under sharper scrutiny, and institutions that miss warning signs could face regulatory pressure.

That approach was reinforced a week earlier, when the Financial Crimes Enforcement Network issued a joint advisory with the FDIC, the OCC and the NCUA, in coordination with the IRS. The June 5 advisory urged financial institutions, especially banks, to watch for fraud schemes and other suspicious or potentially criminal activity involving the unlawful employment of illegal aliens. Treasury said the advisory included 18 red-flag indicators and instructed banks to reference it in Suspicious Activity Reports with the key term FINANCIALINTEGRITY-2026-A002.

Treasury also said information sharing among financial institutions is vital to combating fraud and other financial crimes, placing the immigration directive inside the government’s broader anti-money-laundering and national-security playbook. That matters because access to banking is often essential for paying rent, receiving wages, sending money and building a financial record. By making immigration status a factor in ordinary banking compliance, the administration is moving enforcement beyond the border and into daily economic life.

The banking industry has already started parsing the new directives. The American Bankers Association issued a staff analysis on June 11 focused on the order’s instructions to Treasury, FinCEN and the banking agencies. The Independent Community Bankers of America said it had repeatedly urged the administration not to require community banks to collect citizenship information. The National Consumer Law Center said in a June 2026 issue brief that the order does not immediately change the law, even as it could reshape how banks treat immigrants.
