The Pentagon is looking into dismantling the Military Accessions Vital to the National Interest program, which allowed foreign-born visa holders, asylees and refugees in the U.S. to be put on a fast track for citizenship in return for their service, according to a report Monday morning.
Defense officials recently sent a letter to Defense Secretary Jim Mattis arguing "the potential threat posed by individuals who may have a higher risk of connections to Foreign Intelligence Services" makes the program risky to national security interests.
The senior Pentagon officials also said they do not have enough background information about applicants to properly vet them, according to NPR.
Rescinding the 2009 program could nullify enlistment contracts for approximately 1,000 people of the total 10,400 immigrants who were recruited for their medical and language skills. Ten percent of the total group are currently waiting for naturalization.
The program has been suspended in the meantime.
President Trump campaigned on enhancing immigration policies, but did not take a stance on this military program.
