A newly issued Department of Homeland Security memo outlines plans to expand the temporary detention of certain refugees upon arrival in the United States to allow for additional security screening and identity verification.

The document, circulated internally in recent days, sets out procedures under which refugees flagged for supplementary review may be held for extended processing while federal agencies conduct further background checks.

The memo states that the measures are intended to ensure that all admissions meet the highest national security standards and that identity documentation is fully verified before individuals are released into communities.

Under the proposed framework, refugees identified through interagency screening systems as requiring further review could be transferred to designated facilities pending completion of enhanced vetting.

Officials describe the approach as targeted rather than universal, emphasising that the majority of refugees will continue to undergo standard processing timelines.

The memo also references coordination between Homeland Security, intelligence agencies and law enforcement bodies to address any discrepancies uncovered during biometric or documentary checks.

Authorities argue that the updated procedures reflect evolving global security conditions and advancements in screening technology.

Immigration advocates have raised concerns about potential humanitarian implications, including the impact of prolonged detention on families.

Administration officials, however, maintain that the measures are consistent with existing statutory authority and are designed to balance compassion with security.

The policy direction signals a renewed focus on strengthening safeguards within the refugee admissions system.

Further implementation guidance is expected to be issued as agencies prepare to operationalise the expanded vetting procedures in the coming months.
