The mandate stems from a 2025 congressional report identifying vetting gaps in over 10,000 approved cases with extremism connections. It follows a 2025 migrant surge exceeding 3 million arrivals and several foiled terror plots involving previously vetted individuals. The policy was proposed in late 2025 and finalized after interagency review. Processing timelines remain uncertain, though DHS estimates the enhanced checks will add 6 to 12 months per case.
Immigration rights groups including the ACLU have already challenged the policy as discriminatory, while security advocates support the stricter approach. Attorneys handling immigration matters should prepare for significant delays in case processing and anticipate increased client inquiries regarding social media reviews and AI-driven assessments. The timing—proximate to the 2026 midterms—suggests the policy may face legislative scrutiny or modification before full implementation.
