U.S. Citizenship and Immigration Services (USCIS) is implementing new security-screening measures that will slow the resolution of millions of immigration applications [1].

These changes affect the core of the U.S. immigration system by adding layers of scrutiny to the vetting process. Because the measures target residency and work-permit requests, they may delay the legal status of a significant number of foreign nationals currently living or working in the country.

The new rules stem from an executive order designed to tighten security criteria for those seeking immigration benefits [1]. The agency will apply more rigorous background checks and security filters to applicants before granting visas or residency permits [2].

Officials said that these stricter filters will impact millions of pending files [1]. While the agency has not provided a specific timeline for the increased delays, the added screening steps are expected to create a bottleneck in the processing of residency and work-permit requests [3].

The measures apply to USCIS operations nationwide [1]. This systemic shift in screening protocols means that applicants who previously faced shorter wait times may now experience extended delays as the agency verifies security data against the new criteria [2].

These updates come as the agency manages a massive backlog of cases. The introduction of more stringent filters is likely to prolong the time it takes for the government to reach a final decision on an individual's eligibility for legal status [3].

The shift toward more rigorous security screening suggests a prioritization of national security over processing efficiency. By slowing the resolution of millions of files, the U.S. government is effectively increasing the barrier to entry and residency, which could lead to prolonged legal uncertainty for workers and families awaiting status updates.
