The Trump administration is continuing its push to limit undocumented immigrants' access to the U.S. banking system, urging banks to consider loans to them as potentially risky. Guidance from the Office of the Comptroller of the Currency and two other regulators takes aim at retail loans offered to workers who may not be authorized to work in the U.S.

Those discussions led to an executive order in May directing financial regulators to use existing rules to achieve the administration's goals. Officials have pointed to the use of the banking system by Mexican cartels and Chinese money-laundering groups as a basis for the new policies. An "inadmissible and removable alien population" poses a risk to national security and financial stability, the executive order said.

The latest guidance doesn't change existing underwriting standards but spells out reasons why offering loans to unauthorized workers could be risky. Risks include the possibility of deportation, or that an employer terminates a worker after discovering they don't have valid work authorization, affecting the borrower's ability to repay.
