Washington, D.C. — The U.S. immigration system is facing an unprecedented challenge as the U.S. Citizenship and Immigration Services (USCIS) grapples with a record backlog of more than 11.6 million pending immigration applications and petitions, affecting millions of immigrants, families, employers, and businesses across the United States.
According to the latest available USCIS data and independent analyses, the agency’s pending caseload has more than tripled over the past decade. The backlog stood at approximately 3.5 million cases in 2016 but climbed to nearly 11.6 million by the end of Fiscal Year 2025, making it the largest in USCIS history.
The growing backlog spans nearly every immigration benefit administered by USCIS. These include family-sponsored petitions, employment-based immigration applications, adjustment of status (green card) applications, work authorization documents, naturalization requests, Temporary Protected Status (TPS), humanitarian programs, and affirmative asylum applications. More than 1.5 million affirmative asylum applications alone remain pending, while hundreds of thousands of family- and employment-based petitions continue to await adjudication.
Immigration experts attribute the mounting delays to a combination of factors, including a sharp increase in new applications, reduced case completions, staffing shortages, funding constraints, expanded security screening, and operational challenges that have persisted since the COVID-19 pandemic. During 2025, USCIS completed significantly fewer cases than in previous years while new filings continued to rise, causing the backlog to grow even further.
For applicants, the consequences are significant. Families remain separated for extended periods while waiting for petition approvals. Employment-based immigrants often face lengthy delays in obtaining permanent residency, and employers encounter workforce uncertainty as work authorization applications take longer to process. Naturalization applicants also experience prolonged waits before becoming eligible to vote and fully participate as U.S. citizens. Asylum seekers continue to endure years of uncertainty while awaiting decisions on their protection claims.
Although USCIS has introduced digital processing initiatives and other modernization efforts aimed at improving efficiency, immigration analysts warn that clearing the existing backlog will require sustained increases in staffing, technological improvements, and operational capacity. At current processing rates, experts estimate that it could take well over a year to eliminate the existing inventory of pending applications, even if no additional filings were received during that period.
With millions of immigrants awaiting decisions that affect their families, careers, and futures, reducing the USCIS backlog remains one of the most pressing challenges facing the U.S. immigration system.
