USCIS Switched to the FBI's New Fingerprint Database on April 27. Green Card Approvals Are Stalling.

What happened starting April 27

On April 27, 2026, USCIS activated a new connection to the FBI's Next Generation Identification database — the federal government's most advanced fingerprint and criminal history system. Internal guidance went out that same day directing adjudicators not to approve pending immigration benefit applications until the enhanced security check had cleared.

Within days, a pattern emerged: applicants who had been close to receiving green card approval notices stopped receiving them. April 30 brought reports of a formal pause on I-485 approvals while the new checks ran. People who had passed their naturalization interviews weeks earlier and were waiting only for oath ceremony scheduling found themselves in a hold they had no way to explain from the outside.

This is the story generating the most discussion on immigration forums and in law firm client memos during the first week of May 2026. It is also a story that is getting confused with a different USCIS policy that landed around the same time. These are two separate things. Understanding the difference matters for figuring out what to do next.

The FBI's Next Generation Identification system, in plain English

The FBI has operated fingerprint-based criminal databases for decades. The older system — the Integrated Automated Fingerprint Identification System, or IAFIS — was the standard for immigration background checks for years. The Next Generation Identification system, or NGI, replaced it and extended the database's scope considerably.

NGI links fingerprint records to a broader range of criminal history than the older system reached: arrests that did not result in convictions, records from additional jurisdictions and agencies, expanded data formats, and civil matters. The biometrics themselves are the same fingerprints USCIS collected from applicants at Application Support Centers. What changed on April 27 is which database those fingerprints are being run against, and what information comes back.

USCIS directed its adjudicators to resubmit all pending cases' biometrics through the new NGI interface before issuing any final decision. That is what created the current backlog: not a new biometric collection requirement, but a system-wide re-check of existing fingerprints against a more comprehensive database. Applicants are not being asked to go back to an ASC. The re-check is happening on files already in the system.

Which applications are caught in the freeze

The resubmission directive covers any immigration benefit application that included biometric fingerprint collection as part of the process. That is a wide net. I-485 adjustment of status — the in-country green card application — is directly affected. So is Form N-400, the naturalization and citizenship application. Asylum applications that required biometrics are in the same category. Family-based petitions and employment-based cases where biometrics had been collected are also included.

Cases where biometrics had already been collected and everything else was complete — where the adjudicator needed only to finalize the approval — are the ones most visibly stalled. Naturalization applicants who went through the full interview, answered all questions, and were told to wait for oath ceremony scheduling have had that wait extended by an indeterminate amount. I-485 applicants whose priority dates were current, who had no pending Requests for Evidence, and who had completed biometrics long ago are similarly frozen on the last step.

USCIS has stated that applicants will not generally be required to take any additional action. The re-check is being run internally on fingerprints already on file. You should not schedule a new biometric appointment because of this hold. Doing so does not move your case through the NGI queue.

This is not the same as the high-risk country processing holds

USCIS Policy Memos PM-602-0192 and PM-602-0194, effective in late 2025 and early 2026, placed adjudicative holds on cases filed by nationals of countries designated as high-risk — including Iran, Syria, Venezuela, and dozens of others. Those memos apply based on the applicant's nationality. They were challenged in federal court in Maryland on April 27, and a preliminary injunction was issued protecting 83 named plaintiffs.

The NGI fingerprint resubmission requirement is entirely separate. It does not target any nationality. It applies to all pending cases across all nationalities where biometrics have been collected. If your case is from India, China, Canada, Germany, or anywhere else, and you have a pending I-485 or N-400, you are potentially in the NGI re-vetting queue.

For applicants from designated high-risk countries, both policies may apply simultaneously, which means two independent sources of delay can be stacking on the same case: a nationality-based hold under PM-602-0194 and an NGI resubmission hold under the April 27 guidance. That combination reflects no specific concern about any individual applicant. It is a structural overlap of two separate policy decisions that happen to be in effect at the same time.

Social media screening and the vetting overhaul

The fingerprint database upgrade is the concrete, operational piece of the April 27 change. The broader security overhaul being implemented at USCIS is larger. Reporting drawing on internal USCIS documents describes a vetting framework that includes screening for what officials call "anti-American views" — a phrase that places online speech, social media posts, and public statements inside the same review frame as criminal history and biometric data.

USCIS has described using AI to triage fraud and security issues, translate documents, match biometrics through E-Verify and SAVE, and analyze public data including social media discrepancies involving employment history and other representations. What specific content is being reviewed, what standards are applied to flag a case, and what triggers additional scrutiny beyond the fingerprint check have not been detailed in public guidance.

The fingerprint resubmission directive is the identifiable mechanical cause of the current approval freeze. Whether social media screening is contributing to individual case delays in the short term is harder to assess externally. Both processes are happening simultaneously, but the NGI queue is the one generating the immediate, widespread stall in final approvals.

The 'brief delay' that is still going

When USCIS issued internal guidance directing adjudicators to hold approvals pending the enhanced NGI checks, the agency characterized any resulting delays as expected to be brief. That framing was offered around the April 27 launch date.

As of early May 2026, delays are continuing. The time required for enhanced checks to process through the NGI system is not publicly known. USCIS has not published data on how many pending cases are in the resubmission queue, how many have cleared, or what the processing time looks like under the new system. Law firms reporting on this issue have noted that client inquiries and service requests have yielded limited information about individual case holds.

Case status displays in USCIS's online system are not updating in ways that identify the NGI hold as the specific reason for delay. An applicant looking at a status message showing "case is being actively reviewed" or similar language has always seen that kind of update and cannot use it to confirm whether the NGI re-check specifically is holding their file.

What you should and should not do right now

Do not schedule a new biometric appointment on your own. USCIS has said applicants are not being asked to resubmit fingerprints. Booking an ASC appointment independently does nothing to accelerate your place in the NGI check queue. If USCIS needs anything from you, they will send a notice requesting it.

Do not assume a service request or attorney call to USCIS will lift a system-wide hold. Service requests are useful for case-specific issues: missing documents, RFE response tracking, address changes. They are not designed to override a policy-level directive that applies to thousands of pending cases simultaneously. Your attorney may have no additional visibility into where your case is in the NGI queue beyond what you can see in the online portal.

If your underlying nonimmigrant status — H-1B, L-1, F-1 OPT, or other status — is approaching expiration, that timeline does not pause because your I-485 is in an NGI hold. Status extensions, cap-gap coverage, and other mechanisms remain your responsibility on their own timelines. Waiting for a delayed I-485 approval does not automatically protect you from a status lapse. Get your attorney's assessment of how close your status expiration is to when the I-485 might realistically clear.

Naturalization applicants who completed their N-400 interviews and are waiting for oath scheduling should understand that this is likely a factor in the delay. There is no fixed USCIS deadline for scheduling an oath after an interview passes. If you have travel plans, a passport renewal need, or other time-sensitive reasons for the naturalization, let your attorney know so they can assess whether any formal follow-up is warranted.

The larger pattern this fits

The April 27 NGI launch is the security infrastructure piece of a broader enforcement posture that the current administration has been building across immigration agencies since early 2025. The country-based processing holds under PM-602-0192 and PM-602-0194 were the policy-memo piece. Enhanced consular vetting and social media screening have been separate layers. The NGI upgrade connects the fingerprint collection infrastructure to a more comprehensive criminal history record. Each piece was added at different times through different mechanisms.

For employment-based green card applicants, the practical effect is another variable added to a system already generating significant uncertainty in the first half of FY2026. The May 2026 visa bulletin switch to Final Action Dates narrowed who could file I-485. The country-specific holds affected who could be approved among those who had already filed. The NGI resubmission directive delays when anyone already in the pipeline will receive their approval notice.

None of these changes required legislation or notice-and-comment rulemaking. They are internal policy and technology changes that took effect immediately and can be modified or reversed through the same channels. That is both the frustrating and reassuring part of the current landscape: things can change rapidly in either direction. This article is informational only and does not constitute legal advice.
