- USCIS launched enhanced fingerprint-based vetting on April 27, 2026, causing potential processing delays for several immigration benefits.
- The new process integrates FBI Next Generation Identification data to perform more comprehensive background and criminal history checks.
- Applicants should maintain valid work authorization and travel documents while cases remain pending under the updated security protocol.
(UNITED STATES) — USCIS began using an enhanced fingerprint-based security vetting process on April 27, 2026, a change that can slow final decisions in pending green card, asylum, citizenship and other biometrics-based cases while officers wait for added background-check clearance.
The agency’s shift does not stop every case, and it does not by itself signal a problem in an application. Cases that appeared close to approval can now remain pending until the added fingerprint review is complete.
USCIS expanded fingerprint-based immigration background checks with criminal-history information from the FBI’s Next Generation Identification system, known as Next Generation Identification or NGI. Officers were instructed not to approve cases until the enhanced checks were completed, and to resubmit fingerprints in certain pending matters that had already gone through an earlier FBI review.
USCIS has described the change as a vetting-related adjudication delay rather than a shutdown of fingerprint-based case processing. The agency has also indicated that any delay in issuing decisions should be brief.
The timing reaches across a broad set of immigration benefits because many case types depend on fingerprints or other biometrics before a final decision. That group includes `Form I-485` adjustment of status, `Form N-400` naturalization, asylum applications, family-based and employment-based green card cases, humanitarian filings and other benefits that require fingerprint-based checks.
Pending adjustment of status, naturalization and asylum matters appear among the case types most likely to feel the effect first. Those are all categories in which a case can sit near the finish line while security screening remains a required last step.
Applicants who gave fingerprints before April 27, 2026 face the clearest risk of delay. Their prints may need to be resubmitted or rechecked through the enhanced process before USCIS issues an approval, even if an interview is already complete and no further evidence request is outstanding.
A common green card case shows how the new process can slow movement. An applicant may have filed `Form I-485`, completed biometrics months ago, finished an interview or heard nothing further, and expected a final decision soon; under the new system, USCIS can still hold the case until updated fingerprint clearance comes back.
Officers were directed to resubmit fingerprints for pending cases in which FBI information had been received before April 27, 2026. That means the pause can affect older filings as well as newer ones.
Fresh biometrics appointments will not necessarily follow in every case. Immigration firms have indicated that USCIS can rerun fingerprint-based checks using prints already on file instead of automatically calling each applicant back to an application support center.
Mail and online notices still matter. If USCIS issues a new biometrics appointment notice, the applicant must attend or properly reschedule, because missing that appointment can create another delay and, in some cases, avoidable complications.
Adjustment of status applicants may feel the strain more than most because `Form I-485` depends heavily on fingerprint-based review before approval. A delayed decision can reach beyond the green card itself and affect work authorization renewals, advance parole planning, job changes that depend on portability timing, and dependent family members waiting in the same line.
Children close to aging out can face added pressure if the case remains pending longer than expected. Families tracking Child Status Protection Act issues now have another timing variable to watch while the background review runs its course.
That waiting period also carries practical consequences for applicants who had expected a quick finish. An applicant should not resign from a job, travel abroad, change employers, or allow work authorization to lapse based solely on the expectation that a green card approval will arrive soon.
Naturalization cases can also slow if USCIS requires the enhanced fingerprint review before approval or before scheduling the oath ceremony. The effect can differ by stage: some applicants have already interviewed and are waiting for final clearance, while others may have an oath date set and face less disruption, depending on how USCIS handles the file.
Asylum applicants fall into the same broad pattern because asylum adjudication also depends on identity, security and background screening. Even a temporary hold can complicate work authorization renewals, family reunification planning and legal strategy where immigration court proceedings connect to the case.
Urgent humanitarian matters carry less room for delay. Applicants dealing with emergency travel, removal proceedings, expiring status, age-out concerns or criminal-history issues have stronger reasons to seek legal advice before treating the delay as routine.
Employers sponsoring workers for permanent residence also need to account for slower `Form I-485` approvals. Sponsored workers in H-1B, L-1, EB-2 and EB-3 pathways, along with dependent family members, can remain tied longer to existing work and travel documents while the enhanced checks remain pending.
That can affect assignment planning and international travel. Employers tracking foreign national staff need to watch expiration dates for status, employment authorization documents and advance parole rather than assuming a pending green card case will convert to approval on the expected timetable.
A pending adjustment case should not be treated as approved until USCIS issues the actual approval notice. That point matters for workers planning international trips, employers reviewing internal start dates or transfers, and families making decisions tied to a change in immigration status.
Applicants now have a narrow set of practical steps. They can monitor the USCIS online account, case status page and physical mail for biometrics notices, requests for evidence, interview notices or decision updates, because the delay itself may not come with a detailed explanation.
Work authorization deserves close attention. If an employment authorization document is nearing expiration, renewal timing becomes more important because a green card case that looked ready for approval can now remain pending longer while USCIS completes the enhanced fingerprint-based security vetting.
Travel also requires care. Applicants with pending adjustment cases need valid advance parole or another lawful basis for travel before leaving the United States, since an international trip taken at the wrong moment can create separate immigration problems that have nothing to do with the fingerprint review.
Recordkeeping can help if the case stalls. Copies of biometrics notices, interview notices, EAD and advance parole approvals, `Form I-485` receipts and other USCIS correspondence can become useful if an attorney review, service request or congressional inquiry later becomes necessary.
Most applicants face a processing delay risk, not an automatic denial risk. USCIS is adding a layer of review; it is not treating the existence of a pending fingerprint check as evidence that the case itself fails.
Background checks can still take on legal weight if they reveal arrests, unresolved criminal matters, identity discrepancies, immigration violations or national-security flags. Applicants with prior criminal or immigration history have more to lose from an incorrect response and more reason to seek legal advice before replying to a USCIS request.
The immediate change, then, is procedural but wide in reach. USCIS has tied final decisions more closely to an expanded FBI check through Next Generation Identification, and cases filed long before April 27, 2026 can be pulled into that system if their fingerprints were already reviewed under the older process.
Applicants waiting for a green card, citizenship, asylum decision or another biometrics-based benefit now face a slower path in some cases, even when the file otherwise appears complete. Keeping documents valid, watching for notices and avoiding assumptions about approval timing remain the most concrete safeguards while the enhanced review plays out.
