By FATIMA HUSSEIN and KEN SWEET,  WASHINGTON (AP):- President Donald Trump on Tuesday signed an executive order that requires banks to take a closer look at the citizenship of their customers, a new measure in his administration’s push to clamp down on people living in the country illegally.

The order directs bank regulators and government departments to look for signs that people without legal status are opening accounts or obtaining loans or credit cards. However, the order is less aggressive than banks had expected, as earlier reports suggested the White House was drafting an order that would make collecting customers’ citizenship information mandatory.

In the order, the White House framed the decision that banks would face credit risks if one of their customers were deported and any loans could no longer be repaid. The White House said it would not “permit risks to our financial system posed by the extension of credit or financial services to the inadmissible and removable alien population.”

Since banks have never collected any information about their customers’ citizenship or immigration status, there are no reliable public figures on how much risk these customers pose to the financial system.

A study by the left-leaning Urban Institute estimated that between 5,000 and 6,000 mortgages were issued to customers with Individual Taxpayer Identification Numbers (ITINs). These ITINs are typically used by undocumented workers in place of a Social Security Number. The Urban Institute estimated that banks were highly reluctant to lend to individuals with ITINs. Fannie Mae and Freddie Mac are also generally reluctant to insure mortgages for borrowers with an ITIN, making it even less likely for ITIN holders to obtain a mortgage.

The banking industry had been aggressively lobbying for months to stop the White House from issuing an executive order that would have made collecting customers’ citizenship status mandatory. The argument from the banks was that collecting citizenship information on their customers would require vast amounts of paperwork and would be a great expense for the financial system.

Immigration advocates have previously said any order that would order banks to collect citizenship information would likely result in undocumented immigrants moving out of the financial system, increasing the number of “unbanked” individuals.

The White House has taken other measures to discourage undocumented workers from using the financial system. The Treasury last November announced that it would reclassify certain refundable tax credits as “federal public benefits,” which bars some immigrant taxpayers from receiving them, even if they file and pay taxes and would otherwise qualify.

Tax experts said immigrants brought to the U.S. illegally by their parents as children, known as Deferred Action for Childhood Arrivals, or DACA, recipients, and immigrants with Temporary Protected Status would be largely affected by the planned change.
