- USCIS has implemented enhanced FBI criminal background checks for all fingerprint-based immigration applications starting April 2026.
- New internal guidance mandates re-vetting pending cases if background checks were completed before the new security standards took effect.
- Extreme vetting now includes ideological and social media screening to identify anti-American views or participation in specific protests.
(UNITED STATES) — The Trump administration has ordered expanded security screening for all immigration applicants, adding deeper access to federal criminal databases, wider social media reviews and a recheck of thousands of cases that had already cleared earlier vetting.
U.S. Citizenship and Immigration Services began using enhanced FBI criminal history information for all fingerprint-based checks on April 27, 2026, and internal guidance directs officers to resubmit fingerprints in pending cases if the earlier FBI result arrived before that date. The change reaches across the system, affecting new filings and cases already in the pipeline.
Zach Kahler, a USCIS spokesperson, said the agency had put in place “new security checks to strengthen the vetting and screening of applicants through expanded access to federal criminal databases.” He added on April 28, 2026: “USCIS will always prioritize the safety of the American people. Processing is ongoing as we apply these enhanced background check requirements. Any delay in decision issuance should be brief and resolved shortly.”
The administration has framed the changes as part of a broader extreme vetting push under Executive Order 14161, issued in February 2026. That order directs the Department of Homeland Security to access federal criminal records “to the maximum extent permitted by law,” and administration officials have cast the overhaul as a response to what USCIS called weak prior screening.
In a public alert dated March 30, 2026, USCIS said earlier measures were “wholly inadequate,” and said approvals issued under that system created “national security and public safety risks.” The agency’s alert, [Update on USCIS’ Strengthened Screening and Vetting](https://www.uscis.gov/newsroom/alerts/update-on-uscis-strengthened-screening-and-vetting), laid out the administration’s rationale in blunt terms.
Kahler also defended ideological screening on April 28, 2026 after reports of denials tied to political speech. “If you hate America, you have no business demanding to live in America. Citizenship or a green card are both privileges reserved for individuals who respect and uphold the principles upon which this nation is founded.”
That approach reaches beyond criminal records. Under Executive Order 14161, DHS has expanded social media screening, and training materials say “anti-American” or “anti-Israeli” views can count as “overwhelmingly negative” factors in green card decisions. The examples listed in those materials include participating in pro-Palestinian protests, criticizing Israel on social media, or flag desecration.
The policy marks a shift toward what the administration describes as continuous vetting. USCIS has also recast its officers as homeland defenders, language that signals a broader mission than document review and eligibility checks.
One of the most immediate operational changes sits inside the FBI data stream. USCIS now receives enhanced criminal history record information, or CHRI, for every fingerprint-based background check, and officers must rerun pending fingerprints if the earlier response predates April 27, 2026. That instruction alone creates fresh work across a large inventory of unresolved cases.
Immigration lawyers and other experts have warned that the reruns are likely to slow decisions beyond the brief pause described by USCIS. Every case sent back through the system adds another review step, another response queue and, in some instances, another round of follow-up questions.
The administration has paired the database changes with broader case scrutiny. Applicants now face more Requests for Evidence, mandatory in-person community interviews and demands for five years of social media history. Those added steps can affect employment-based petitions, family-based cases, adjustment applications and naturalization matters alike because the policy applies across the applicant pool.
Another part of the initiative reaches people who were already admitted. Operation PARRIS, short for Post-Admission Refugee Reverification and Integrity Strengthening, calls for re-interviews and merit reviews of resettled refugees, primarily those who entered between Jan 2021 and Feb 2025, to determine whether their original claims were valid.
DHS announced that effort on January 9, 2026 in a press release, [DHS and USCIS Launch Operation PARRIS in Minnesota](https://www.uscis.gov/newsroom/news-releases/dhs-launches-landmark-uscis-fraud-investigation). The program adds a second look at approvals that had already led to entry and resettlement, widening the administration’s review beyond pending applications.
Country-based restrictions remain in place as well. Three policy memoranda, PM-602-0192, PM-602-0193 and PM-602-0194, put adjudicative holds on benefit applications filed by nationals of 39 designated high-risk countries. Refugees and long-term residents from those countries face indefinite pauses in green card or naturalization cases while a layered vetting plan is completed.
The holds add another layer to a system that already depends on fingerprint checks, database responses and officer interviews. A person can clear one stage and still wait because a country-specific review remains open, or because a file has been sent back for another biometric run under the new FBI integration.
The administration has also shortened the maximum validity period for certain Employment Authorization Documents. The cap fell from 5 years to 18 months, a change meant to force more frequent revetting and bring more applicants back into the screening system on a shorter cycle.
That shorter validity window carries practical effects far beyond the card itself. Applicants who need proof of work authorization will return to USCIS more often, generating more renewal filings and more background checks at a time when the agency is already adding new screening layers to pending cases.
Administration officials say the effort closes security gaps left by the previous administration and helps identify “criminal actors” and people with “hostile attitudes toward American institutions.” The wording matches the policy’s central premise: immigration benefits should turn not only on statutory eligibility, but also on a broader reading of conduct, online expression and national security risk.
The policy also widens the role of digital review in immigration adjudications. Social media history, protest participation and political commentary now sit closer to the center of a benefit decision, particularly in cases involving green cards and naturalization, where an officer can weigh adverse material alongside the rest of the record.
Kahler has insisted that processing continues while the new checks take effect. His public statement offered a narrow assurance on timing, saying any delay in decision issuance should be brief and resolved shortly, but the scale of fingerprint resubmissions and repeat interviews has raised expectations of bottlenecks inside the agency.
Those bottlenecks are likely to appear first in files that were otherwise ready for decision but now need another FBI response. Cases involving refugee admissions, applicants from the 39 listed countries, or records flagged for ideological review can move even more slowly because those files face multiple layers of screening rather than one.
The administration’s public rollout has come through a mix of newsroom alerts, press office statements and policy guidance. USCIS has pointed applicants and practitioners to its [Policy Manual](https://www.uscis.gov/policy-manual) for vetting and screening updates under EO 14161, while the March 30, 2026 alert and the January 9, 2026 Operation PARRIS release give the clearest public description of the push now underway.
Taken together, the changes amount to a broad reordering of how the government reviews immigration benefits under the Trump administration. Criminal records checks now draw from a deeper federal data pool, ideological screening has become explicit policy, and approvals once considered settled can be reopened for another look.
