The number of migrants approved for U.S. citizenship has fallen by roughly 50 percent compared to the previous year, according to recent data from U.S. Citizenship and Immigration Services (USCIS) cited by NPR. The drop comes amid policy changes implemented under the Trump administration that officials say are aimed at strengthening vetting procedures and ensuring stricter eligibility standards.

USCIS data shows significant volatility throughout 2025, including an early spike in approvals followed by a sustained decline. At one point during the year, monthly naturalization approvals reached 88,488, the highest level recorded since the agency began tracking monthly figures in 2022. However, by January, approvals had fallen to 32,862, marking the lowest monthly total in that dataset.

Application volume also declined sharply over the same period. In October 2025, 169,159 individuals applied for citizenship, but by November that figure had dropped to 41,478, reflecting a significant reduction in new filings as the year progressed.

An USCIS spokesperson attributed the shift to enhanced screening measures, including renewed emphasis on civics testing standards, expanded English-language requirements, and increased review of applicants’ background information. The agency also indicated that additional vetting tools, such as social media screening and restored neighborhood investigations, are being used to assess applicants’ eligibility and “good moral character.”

The administration has framed the changes as part of a broader effort to reinforce immigration integrity and ensure that citizenship is granted only after a thorough evaluation. Officials argue the adjustments are necessary to maintain confidence in the naturalization process.

The decline in approvals has coincided with broader changes in both legal and illegal immigration flows, according to the same reporting. Analysts note that shifting policy expectations and increased scrutiny may have influenced both application behavior and processing timelines throughout the year.
