Vetting errors were found in 40% of Afghan migrants' asylum applications following the Biden administration's withdrawal from Afghanistan, according to a Department of Homeland Security inspector general report. 

The inspector general's analysis examined a sample of 678 asylum applications from Afghans who resettled in the U.S. under the Operations Allies Welcome program. 

Of those applications reviewed, 303 had missing aliases and 23 had missing security checks. More than 160 had other documentation issues or incomplete records resolution. Two of the cases reviewed would have likely been deemed inadmissible on terrorism-related grounds. 

"The prevalence and type of errors suggest U.S. Citizenship and Immigration Services may have missed opportunities to potentially link names provided by applicants to derogatory information, which in turn would compromise the integrity of alien registration file (A-File) contents that future users rely upon for immigration administration and enforcement activities," the report states.
