A sweeping internal review of the Biden administration’s Afghan resettlement program has found that roughly 40 percent of the evacuees who entered the United States after the chaotic 2021 withdrawal failed to pass initial security and background checks, according to multiple government sources familiar with the findings. The failure rate, described by officials as “alarming,” has intensified scrutiny of the Department of Homeland Security’s handling of the largest humanitarian airlift in modern U.S. history — a program that brought more than 80,000 Afghans to American soil in a matter of weeks.
**Context**
Operation Allies Welcome, launched in August 2021, was designed to rapidly relocate Afghans who worked alongside U.S. forces or faced imminent Taliban reprisals. Evacuees were initially processed at military bases and later transferred to communities nationwide. However, from the outset, the vetting process was fragmented and rushed. The standard procedure requires applicants to undergo biometric and biographic checks against terrorist watchlists, criminal databases, and immigration records. But the crush of arrivals, combined with limited staff and destroyed Afghan infrastructure, forced U.S. officials to rely on incomplete data and rapid interviews.
The 40 percent failure rate — meaning that for every five evacuees, two were flagged for insufficient identity verification, missing documents, or potential security concerns — emerged from a comprehensive audit conducted by the DHS Inspector General’s office earlier this year. While flagged does not automatically mean denial or removal, the high proportion of problematic cases suggests deep systemic flaws. Many of those initially flagged were later granted entry after supplemental checks, but the audit warned that “significant gaps remain in the ability to definitively clear all entrants.”
These findings come on the heels of earlier, more limited disclosures. A 2023 Government Accountability Office report found that 96 percent of Afghan evacuees were admitted before undergoing full background checks, a statistic that drew bipartisan condemnation at the time. The new 40 percent figure, which focuses specifically on the initial screening stage, paints an even starker picture of the program’s vulnerabilities.
**Analysis**
The implications of this failure rate are profound for both national security and the Biden administration’s migration policies. Critics argue that the high vetting failure rate exposes a reckless approach to mass migration under the guise of humanitarian relief. Republican lawmakers have seized on the audit as evidence that the administration prioritized speed over security, potentially allowing individuals with unknown backgrounds to enter the country. Some have called for a moratorium on further Afghan arrivals until a rigorous case-by-case review is completed.
Supporters of the program, however, caution against overreading the data. They note that the “failure” rate refers to initial vetting, which by design casts a wide net to catch possible risks. Most of those initially flagged ultimately passed deeper checks, officials say. Moreover, the chaotic environment in Kabul — with destroyed records and fleeing applicants — made perfect verification impossible. The alternative, they argue, would have been to abandon thousands of allies to Taliban reprisals. The debate thus centers on whether the program’s outcomes justify the risks incurred during the emergency operation.
Beyond the immediate political firestorm, the 40 percent failure rate raises systemic questions about U.S. refugee and parole vetting protocols. The Afghan operation is now being used as a case study for how the United States might handle future mass evacuations — from Ukraine, Gaza, or other conflict zones. If the flagship program suffers such a high rate of initial screening failures, confidence in the entire humanitarian parole system may erode. Some analysts predict stricter biometric requirements, longer processing times, and more robust interagency coordination in any future emergency admission programs.
