On June 5, the U.S. Treasury Department issued an advisory through the Financial Crimes Enforcement Network (FinCEN), urging financial institutions, including banks and casinos, to be vigilant against signs of illegal employment of immigrants. Treasury Secretary Scott Bessent stated that this initiative is part of the Trump administration's broader crackdown on illegal immigration, aiming to secure the financial system from exploitation. The advisory points out that employing unauthorized workers can provide unfair advantages to employers, suppress wages, and contribute to criminal activities such as drug and human trafficking. Financial institutions are encouraged to look for indicators of fraud, including shell companies and identity theft. In 2025, suspicious activities linked to payroll fraud schemes amounted to over $2.5 billion, with one significant scheme costing the U.S. more than $38 million in tax revenue. The advisory extends to various sectors, including credit unions, money services, the insurance industry, and mortgage companies, emphasizing the need for vigilance across the financial landscape.
