USCIS Places Many Domestic Immigration Filings on Hold as Vetting Rules Tighten

(UNITED STATES) — USCIS has placed temporary adjudicative holds on many domestic immigration cases while it rolls out stricter vetting rules that took shape from late 2025 through May 2026, according to agency and Department of Homeland Security statements.

The action does not amount to a formal filing ban. USCIS is still accepting cases, but it has paused many final decisions while officers complete added screening, re-run security checks and hold some files for extra review.

On March 30, 2026, the agency announced what it called a “Strengthened Screening and Vetting” initiative. USCIS said, “Through an ongoing comprehensive review of pending workloads and benefit applications, USCIS ascertained that prior screening and vetting measures were wholly inadequate. Our top priority is ensuring that all individuals seeking immigration benefits are properly vetted, particularly those from identified high-risk countries.”

That announcement followed a policy memorandum dated January 1, 2026. In Policy Memorandum PM-602-0194, USCIS directed officers to stop short of final action in certain cases, saying, “Effective immediately, this memorandum directs USCIS personnel to: Place a hold on all pending benefit applications for aliens listed in Presidential Proclamation (PP) 10998. regardless of entry date.”

DHS added another marker on February 20, 2026, when a spokesperson tied the changes to asylum and work authorization cases. “The Trump administration is strengthening the vetting of asylum applicants and restoring integrity to the asylum and work authorization processes. Aliens are not entitled to work while we process their asylum applications,” the spokesperson said.

Together, those statements mark a broad policy shift inside USCIS. The agency has moved from expedited processing toward maximum vetting, with officials framing the change around national security and the integrity of the immigration system.

A second operational change arrived on April 27, 2026, when USCIS deployed an upgraded fingerprint-based FBI security check system. Officers must re-submit fingerprint data for pending cases if the original background checks went to the FBI before April 27, 2026.

That re-vetting pause reaches cases already in the pipeline rather than blocking new filings at the front door. Applicants can still submit petitions and applications, but many final approvals and denials now wait until USCIS finishes the renewed security review.

USCIS has also imposed high-risk country holds under PM-602-0194. A mandatory hold and review applies to benefit requests from nationals of 39 countries identified in Presidential Proclamations 10949 and 10998, including Syria, Mali and Burkina Faso.

Under that policy, officers can move a case forward through much of the process but cannot issue an approval or denial until what the agency calls comprehensive review is complete. That leaves the file active, but not finished.

Another piece of the rollout is Operation PARRIS, a newly launched initiative led by the USCIS Vetting Center. It conducts what the agency describes as data fusion checks using social media, financial networks and criminal history for refugee and high-risk claims.

The reach of the new vetting rules extends beyond newly filed cases. USCIS has said it is reviewing benefits granted as far back as January 20, 2021 to determine whether prior screening met current standards.

That retroactive element has raised the stakes for people with pending applications and for some who already received benefits. The agency has made clear that processing speed now ranks behind what it sees as closing security gaps.

Applicants seeking Adjustment of Status through Form I-485, Naturalization through Form N-400 and Asylum through Form I-589 have been caught in the slowdown. USCIS officials said in April that delays should be “brief,” but practitioners report that thousands of cases have effectively stalled.

Work authorization has shifted as well. USCIS has reduced the maximum validity of many employment authorization documents, or EADs, from 5 years back to 18 months or 1 year, increasing the frequency of security re-vetting.

Biometrics are part of the same effort. USCIS is re-submitting fingerprints already on file in older pending cases, and some applicants are receiving new appointment notices for enhanced biometrics or social media identifiers.

Those added steps have started to affect events that usually mark the end of the process. Some naturalization oath ceremonies and green card interviews have been postponed after officers pulled files back into the re-vetting queue.

The policy architecture shows how USCIS is using adjudicative holds rather than a blanket shutdown. Cases can continue moving through intake and intermediate review, but final decisions now depend on layered checks that were not part of many files when they were first submitted.

That distinction matters inside field offices and service centers. Officers now have to account for the new FBI fingerprint re-check, country-based hold rules and Operation PARRIS screening before they close out affected cases.

USCIS has directed the public to its Newsroom alerts page for updates tied to the Strengthened Screening and Vetting initiative. The agency’s policy memoranda page includes the directives behind the holds and review process.

DHS has published related announcements on its news page, including statements on asylum and work authorization vetting. Taken together, the documents show a system that still accepts filings but now withholds many final outcomes until expanded screening is done.

The result is a domestic immigration process that looks open on paper but slower in practice. USCIS has tied that slowdown to stricter vetting, broader re-checks and a willingness to revisit screening standards reaching back to January 20, 2021.
