The number of foreigners approved for U.S. citizenship dropped by roughly 50 percent after the Trump administration overhauled screening procedures at U.S. Citizenship and Immigration Services, with new applications falling just as sharply, from more than 169,000 in a single month to barely 41,000 weeks later, according to USCIS data reported by NPR.
The numbers tell a stark story. At its 2025 peak, USCIS approved 88,488 naturalization applications in one month, the highest single-month total since the agency began tracking month-by-month data in 2022. By January of this year, that figure had collapsed to 32,862, the lowest the agency has ever recorded.
Applications for citizenship followed a similar trajectory. In October 2025, 169,159 foreigners filed for naturalization. By the end of November, the number had tumbled to just 41,478, a 75 percent drop in roughly six weeks.
The decline tracks directly to a Department of Homeland Security review process set in motion by the Trump administration. USCIS spokesman Matthew Tragesser told NPR the agency is now taking a harder look at applicants from high-risk countries and has layered in multiple new screening measures.
Tragesser laid out the specifics:
“This includes reimplementing the 2020 naturalization civics test for 2025, strengthened English language requirements, screening social media for anti-American activities, and restoring neighborhood investigations to ensure applicants demonstrate good moral character and an attachment to the Constitution.”
Each of those items represents a tightening of standards that had been loosened or abandoned under the Biden administration. The 2020 civics test, for instance, was replaced during the Biden years; its reinstatement raises the bar for applicants who must demonstrate basic knowledge of American government and history. Social media screening adds a layer of vetting that goes beyond paperwork. And neighborhood investigations, a throwback to an earlier era of immigration enforcement, put real-world verification behind claims of good moral character.
Tragesser summed up the agency’s posture bluntly:
“USCIS will not take shortcuts in the adjudications process.”
That single sentence captures the philosophical shift. For years, critics on the right argued that USCIS had become a rubber stamp, processing applications at volume without adequate scrutiny. The Trump administration’s position, as articulated by its own spokesman, is that speed was never the point. Integrity is.
The data contains an irony worth noting. During the first few months of Trump’s second term, the administration actually approved a record-high number of naturalizations. That surge likely reflected a backlog of applications filed during the Biden era finally working through the pipeline. Once the new screening protocols took hold, the approval rate dropped fast.
The pattern, a brief spike followed by a sharp, sustained decline, suggests the reforms are biting in real time. Applicants who might have sailed through under looser standards now face a longer, more demanding process. Some may be withdrawing applications rather than submitting to enhanced scrutiny. Others may simply be waiting.
The administration’s broader immigration enforcement posture extends well beyond naturalization. Courts have become a frequent battleground, as a recent D.C. Circuit ruling rebuking a federal judge over Trump deportation flights made clear.
The drop in new applications may be the more telling number. Approvals can fluctuate based on processing speed and staffing. But when fewer people bother to apply in the first place, it signals something different: a change in expectations.
Going from 169,159 applications in October 2025 to 41,478 by November’s end is not a seasonal dip. It is a structural shift. Prospective applicants, and the immigration attorneys who advise them, appear to have gotten the message that the rules have changed.
State governments have been moving in a similar direction. Mississippi recently passed a bill making illegal immigration a state crime, sending it to the governor’s desk in a sign that enforcement pressure is building at every level of government.
Meanwhile, legal challenges to the administration’s immigration agenda continue to pile up. A Biden-appointed judge halted the administration’s move to end Temporary Protected Status for Ethiopia, and separate litigation has targeted deportation actions in other cases. The administration faces resistance in courtrooms even as its administrative reforms produce measurable results at USCIS.
Several questions remain unanswered by the available data. USCIS has not specified which countries fall under its “high-risk” designation or how many applicants from those nations have been flagged under the new screening protocols. The agency has not disclosed how many applications have been denied versus delayed, a distinction that matters enormously to the people in the pipeline.
Nor is it clear how much of the decline in approvals reflects genuine enforcement of higher standards versus simple bureaucratic slowdown. Restoring neighborhood investigations, for example, requires manpower. If the agency lacks the staff to conduct them at scale, the result could be a growing backlog rather than a cleaner process.
Courts have also weighed in on adjacent immigration matters, including a federal judge’s permanent block on Kentucky offering in-state tuition to illegal immigrants, another front in the broader debate over what benefits and pathways should be available to non-citizens.
The 50 percent figure itself, while dramatic, is drawn from a relatively short tracking history. USCIS only began publishing month-by-month naturalization data in 2022, meaning the baseline for comparison covers just a few years, years dominated by the Biden administration’s permissive approach. Whether the current numbers represent a return to historical norms or something genuinely unprecedented is hard to say without longer-term data.
For years, the conservative case on immigration has been straightforward: legal immigration should be orderly, merit-based, and conducted with genuine scrutiny. The complaint was never that people wanted to become Americans. It was that the system had become a conveyor belt, processing volume at the expense of standards, waving through applicants without verifying whether they met the requirements that citizenship is supposed to demand.
The Trump administration’s reforms at USCIS represent a direct answer to that complaint. Reimposing the civics test, strengthening English requirements, screening social media, restoring neighborhood checks, these are not exotic measures. They are the kind of basic due diligence that most Americans assumed was already happening.
The fact that implementing them cut approvals in half tells you more about the previous system than it does about the current one.
Critics will call the decline a crisis. But a country that takes citizenship seriously should expect the process to be demanding. The real question is not why the numbers fell. It is why they were ever that high.
