A new study shows that nearly half of the estimated 800,000 illegal aliens shielded from deportation under Obama’s Deferred Action for Childhood Arrivals (DACA) program have previously worked in the United States even though they didn’t have valid Social Security numbers.

Conducted by the University of California, San Diego, the study reveals that nearly 44 percent of DACA recipients had to use fake or ill-gotten Social Security numbers in order to work.

Center for Immigration Studies researcher Ronald Mortensen pointed out, “These individuals were unable to legally obtain Social Security numbers for their pre-DACA employment, which means that they used fraudulently-obtained Social Security numbers that all-too-often belong to American citizens, including American children.”

The practice of using unlawfully-obtained Social Security numbers by individuals eligible for a DACA status is so pervasive, said Mortensen, that the Obama administration actually told applicants not to disclose their illegally obtained numbers. “That ensured that Americans who are the victims of DACA identity theft were left with destroyed credit, arrest records attached to their names, unpaid tax liabilities, and corrupted medical records while the DACA recipients walked away scot-free from multiple felonies — forgery, Social Security fraud, perjury on I-9 forms, and identity theft.”

Mortensen suggests that President Trump’s administration creates a plan, called “DACA Victims’ Restitution Fund,” in which DACA-protected illegal aliens who have previously worked with stolen Social Security numbers have to pay a fine to their American victims, ranging from $3,000 to $5,000.

Under Mortensen’s plan, if DACA recipients cannot pay their fine, the open borders and cheap labor lobby would be allowed to help each illegal alien raise the funds needed to pay back their American identity theft victims.

The revelation of potential mass identity theft by DACA recipients comes as GOP lawmakers are crafting two separate pieces of legislation that aim to give permanent amnesty to the illegal aliens, as Breitbart News reported.

A former official with the United States Citizenship and Immigration Services (USCIS) recently estimated that the fraud rate in the DACA program was at roughly “40 to 50 percent,” if not higher.

In a last-minute push, the Obama administration added 122,221 DACA recipients to the amnesty program in the final three months of his presidency.

At the time, immigration expert John Miano told Breitbart Texas that the approval rate for DACA in Obama’s last three months stood at approximately 98 percent, leaving the potential for rampant fraud and abuse in the program.

Since DACA’s inception, more than 2,100 of the illegal aliens saw their protected status revoked for being involved in gang activity, or when suspected/convicted of a felony. However, a loophole in the DACA program has allowed more than 39,000 illegal aliens to obtain Green Cards and more than 1,000 to be naturalized.
