Know Your American Customer Act

Summary

The Know Your American Customer Act would require insured banks and insured credit unions to verify the citizenship or lawful immigration status of certain individuals before opening or maintaining accounts. It directs covered institutions to accept specified documents as proof of U.S. citizenship or lawful presence, including passports, birth certificates, naturalization and citizenship certificates, permanent resident cards, certain foreign passports with valid immigration records, and other documents later approved by the Secretary of Homeland Security. The bill also creates a special process for individuals with temporary authorized stay, requiring periodic re-verification and, if updated proof is not provided, a staged restriction and eventual closure of the account. The bill further requires institutions to freeze or close accounts for individuals who are not lawfully present, establishes civil penalties for institutions that fail to comply, and assigns enforcement to Treasury’s Financial Crimes Enforcement Network, with coordination from the National Credit Union Administration for credit unions. It also directs Treasury to issue interim guidance within 30 days and final regulations within 90 days, and it expressly preempts conflicting state laws on residency verification by financial institutions. In addition, the bill amends federal criminal law to impose fines and possible imprisonment on certain noncitizens who open or maintain active accounts, including through legal entities, while carving out exceptions for some recent overstays and pending asylum applicants.

Impact

If enacted, the bill would amend Title 31 of the U.S. Code, particularly the Bank Secrecy Act provisions in section 5318 and related criminal penalty provisions in section 5322. It would impose a new federal customer-verification regime on insured depository institutions and insured credit unions, require account screening for citizenship and lawful presence, and authorize federal enforcement and penalties for noncompliance. It would also supersede state laws that regulate lawful-residency verification by financial institutions, creating a uniform federal standard and potentially displacing stricter or different state requirements.

Sentiment

Because there are no committee transcripts or recorded votes provided, the available context shows no formal legislative sentiment beyond introduction and referral. Based on the bill text, the measure appears designed to tighten financial-account eligibility rules and immigration-status verification, which suggests it would likely draw support from proponents of stricter immigration enforcement and opposition from those concerned about access to banking, privacy, and burdens on financial institutions and immigrant communities. The bill has not yet advanced beyond committee referral in the provided record.

Contention

The main points of contention are likely to be the requirement that banks and credit unions verify lawful presence, the mandatory closure or freezing of accounts for individuals who cannot update documentation, and the criminal penalties tied to account access by noncitizens. Critics may argue that the bill could exclude lawful immigrants with temporary status, create compliance burdens, and interfere with access to basic banking services, while supporters may view it as a tool to prevent misuse of the financial system and strengthen immigration enforcement. The preemption of state law is another likely flashpoint, since it would override state-level approaches to residency verification.
