Federal inspectors found that 40% of asylum applications reviewed for Afghan nationals admitted under the Biden administration's Operation Allies Welcome programme contained vetting or documentation errors. These deficiencies—including 303 missing aliases, 23 absent security checks, and over 150 additional documentation gaps—increased the risk that ineligible applicants could have been admitted, with at least two cases potentially involving terrorism-related grounds for inadmissibility. The report's findings carry particular weight given recent high-profile arrests of Afghan nationals from the programme, including an alleged ISIS-K supporter and individuals charged with making terroristic threats.

A Department of Homeland Security Office of Inspector General report examined 678 asylum applications and concluded that a lawsuit settlement requiring 90% of applications to be processed within 150 days forced the immigration agency to prioritise processing speed over security thoroughness. Nearly 60% of missing security checks resulted from failed FBI name checks, whilst one applicant had 124 known aliases on record. Two applications involving potential terrorism concerns were flagged as having incomplete security reviews, with one case lacking required documentation and another having supervisors fail to complete the final approval step.
