On April 27, 2026, U.S. Citizenship and Immigration Services quietly flipped a switch that sent shockwaves through the immigration system.
An internal USCIS email, first reported by Reuters, stated: "Effective April 27, 2026, USCIS will begin receiving enhanced criminal history record information (CHRI) for all fingerprint-based background checks submitted to the FBI's Next Generation Identification system."
The directive is sweeping in scope.
Internal guidance by USCIS directed officers to refrain from approving any pending cases that have not undergone the expanded background checks.
For pending cases where fingerprint-based background checks were submitted to the FBI prior to April 27, 2026, USCIS officers are now required to re-submit the applicant's fingerprints to the new FBI system for re-vetting.
The result: a near-total freeze on approvals across a massive swath of the immigration system.
What Changed — and Why
The change stems from a February 6, 2026 Executive Order titled "Protecting the National Security and Welfare of the United States and Its Citizens From Criminal Actors and Other Public Safety Threats," which directed the Department of Justice to share criminal history record information with USCIS to the maximum extent permitted by law.
While officers already received basic fingerprint clearances, the new protocol delivers a much deeper Criminal History Record Information (CHRI) file, including state-level and even municipal arrest records that previously took weeks to obtain manually.
The fingerprint re-vetting is part of a broader overhaul USCIS announced on March 30, 2026.
Over the past several months, USCIS has reviewed and updated screening and vetting practices, including shortening validity periods for certain Employment Authorization Documents, updating photograph reuse policies, increasing social media and financial vetting and community interviews, and launching Operation PARRIS to conduct additional background checks, re-interviews, and merit reviews of refugee claims.
The Atlanta-based Vetting Center can conduct supplemental reviews of pending cases and approved cases, using classified tools alongside database searches and automated matching.
Scale of the Impact
The numbers are staggering.
USCIS data shows approximately 11.6 million cases are currently pending across all application types, the largest backlog in the agency's history.
The pending applications in the "backlog" include forms to become a citizen, acquire a green card, work or seek asylum. There are also 247,974 applications in what USCIS calls the "frontlog," which is tracked separately.
Internal guidance directs adjudicators to resubmit biometrics for every still-pending Form I-485, I-765, N-400, and dozens of other forms.
Newly filed applications will be submitted for background checks after the pending-case backlog completes the new review.
Pending adjustment of status, naturalization, and asylum applications are among the most common case types likely to be affected.
AILA is reporting that while the initial impact appeared to be limited to adjustment of status cases and asylum cases, it could be a much broader hold impacting all USCIS adjudications.
USCIS Response: "Brief" Delays
USCIS has attempted to reassure applicants.
In a statement to U.S. media, a USCIS spokesman said the agency "has implemented new security checks to strengthen the vetting and screening of applicants through expanded access to federal criminal databases."
USCIS said that "any delay in decision issuance should be brief and resolved shortly."
However, the agency has provided no concrete timeline.
The agency has not defined what "shortly" means in operational terms, and it remains unclear how many pending cases are affected or how long the re-vetting queue will take to clear.
USCIS officers are charged with re-submitting the fingerprints already on file; no action should be required on the part of the applicant.
Pending applicants are not receiving direct notices tied to the new screening requirement. Instead, they must monitor case status online while cases remain frozen until the new checks finish.
Real-World Consequences for Applicants
The practical fallout extends far beyond processing delays. Immigration attorneys across the country are flagging urgent concerns for their clients.
Employment Authorization at Risk.
The enhanced vetting creates immediate pressure for applicants whose work authorization may expire during the delay. No grace periods were noted, and the risk of status lapses rises when employment documents or temporary protections run out before USCIS completes the updated vetting.
Delays in adjustment adjudication may have knock-on effects for EAD and advance parole processing, particularly where linked to pending I-485 applications. Other benefits requests requiring biometrics, including H-4 EAD applications, may also experience adjudication holds.
Travel Risks.
Foreign nationals with a pending I-485 who do not yet have a valid advance parole document should refrain from international travel.
Compounding Holds.
Beyond corporate mobility, the policy intersects with the ongoing pause on applications from nationals of 39 "high-risk" countries, meaning those applicants face two independent holds.
At the same time, USCIS has shortened the validity of many Employment Authorization Documents from two years to one so that background checks cycle more frequently.
Litigation Mounts
The adjudication freeze is generating a wave of federal court challenges.
A Northern District of California judge ordered USCIS to decide 32 long-stalled EAD applications by mid-May, hinting that blanket holds may violate the Administrative Procedure Act.
That case, Behdin v. Edlow,
involved a preliminary injunction covering 32 plaintiffs and their I-765 applications within 180 days.
In Meschi v. Edlow, Magistrate Judge Alex G. Tse issued an order enjoining USCIS from applying the hold policies to the plaintiffs' Form I-765 applications and directing USCIS to resume adjudicating those applications. The court found plaintiffs likely to prevail on their APA claim while also finding irreparable harm.
Relief remains limited to the named plaintiffs in each case; no court has yet enjoined the policies nationwide.
But more cases are in the pipeline, and practitioners expect the litigation pressure to intensify.
What Applicants Should Do Now
For the millions of individuals caught in this re-vetting dragnet, immigration attorneys recommend several immediate steps:
- Monitor your USCIS online account regularly for any case status changes or Requests for Evidence.
- File EAD renewals early.
- Do not travel without valid advance parole. Departing the U.S. without proper documentation while an adjustment of status is pending could result in abandonment of the application.
- Keep your address current with USCIS.
- Consult immigration counsel — especially if your documents are expiring in the near term or you have any criminal history, however minor.
The Bigger Picture
This fingerprint re-vetting initiative does not exist in isolation. It is the latest layer in what amounts to the most aggressive overhaul of USCIS screening and vetting protocols in years.
USCIS stresses that the tighter screening is "permanent, not a surge measure."
Through an ongoing comprehensive review, USCIS ascertained that prior screening and vetting measures were "wholly inadequate," claiming that many applicants for naturalization and lawful permanent residence were not sufficiently vetted and that applications were approved and individuals naturalized "who should not have been."
Critics counter that the administration created the conditions for this crisis.
As Elizabeth Jacobs of the Center for Immigration Studies noted, "the longer someone has a pending application, not only are they denied those benefits but could be incurring unlawful presence."
For now, millions of applicants find themselves in an indefinite holding pattern — their fingerprints cycling back through a new system, their lives and livelihoods hanging on the promise that the wait will be "brief."
