U.S. Citizenship and Immigration Services is implementing stricter security controls that have created new delays for visa, asylum, and citizenship applications.
These processing hurdles affect millions of applicants seeking legal status. The delays stem from a combination of expanded criminal background reviews and repeat biometric data collection designed to prevent fraud and increase national security.
According to reports, more than 11 million immigration cases were pending between January 2024 and March 2025 [1]. This record backlog is attributed by some experts to policies enacted by the Trump administration—specifically those introduced between 2017 and 2021—though other reports simply note the delays without linking them to specific political eras [1, 3].
The current bottlenecks involve coordination between USCIS and other Department of Homeland Security agencies, including Immigration and Customs Enforcement (ICE) and the FBI. The tightened vetting procedures have left many applicants in a state of limbo while the government verifies data.
Further changes to the system are expected this month. New USCIS rules are scheduled to take effect in May 2026 [2]. These rules are part of a broader effort to tighten the vetting process for those seeking immigration benefits in the U.S.
Applicants are facing a landscape where security requirements have become more rigorous. The administration said the measures are necessary to ensure the integrity of the immigration system and to prevent fraudulent entries into the country [1, 3].
“More than 11 million immigration cases were pending between January 2024 and March 2025.”
The convergence of legacy policies from the 2017-2021 period and new regulations taking effect in May 2026 suggests a long-term shift toward a security-first immigration model. By prioritizing exhaustive vetting and repeat biometric verification over processing speed, the U.S. government is accepting a larger administrative backlog as a trade-off for higher security thresholds.
