On September 30, 2025, U.S. Citizenship and Immigration Services (USCIS) announced the completion of Operation Twin Shield, an immigration fraud investigation conducted in the Minneapolis-St. Paul region from September 19 to September 28, 2025. Labeled a "resounding success" by USCIS Director Joseph B. Edlow, the Operation marks the beginning of a nationwide crackdown on purported immigration fraud. 

What is Operation Twin Shield? 

Over the course of ten days, USCIS officers worked with U.S. Immigration and Customs Enforcement (ICE), the Federal Bureau of Investigation (FBI), the Drug Enforcement Administration (DEA), and other federal agencies to investigate over 1,000 cases that had indicators of fraud or ineligibility in the Minneapolis-St. Paul region. The investigation targeted individuals with pending marriage and family-based applications, employment-based petitions, and other requests for immigration benefits. 

According to USCIS, it conducted more than 900 site visits and in-person interviews and uncovered fraud, non-compliance, or public safety and national security concerns in 275 cases. USCIS further stated that immigration fraud was detected in 44% of cases interviewed. At a press conference held on Tuesday, USCIS Director Edlow explained that the types of violations discovered include "blatant marriage fraud, visa overstays, people claiming to work at businesses that can't be found, forged documents, abuse of the H-1B visa system, abuse of the F-1 visa, any many other discrepancies." 

As a result of the Operation, USCIS has issued Notices to Appear (NTAs) or referred 44 individuals to ICE. Four individuals have been apprehended thus far. At the press conference, ICE Field Officer Sam Olsen declined to state the number of individuals who have been arrested and detained as a result of the Operation. He confirmed only that multiple arrests have been made and that "arrests are ongoing."

What's Next?

Operation Twin Shield is the first of many potential large-scale immigration fraud investigations. Director Edlow asserted, "we are declaring war on immigration fraud...we will continue to pursue those who seek to abuse our immigration system using every tool at our disposal." Not only has USCIS garnered the support of other federal agencies, but it was also recently granted certain law enforcement powers from the Secretary of the Department of Homeland Security, Kristi Noem. 

With these resources, USCIS plans to use the data and patterns identified during Operation Twin Shield to analyze and cross-check other pending cases nationwide. It may even reopen previously granted immigration benefits to determine whether rescission or revocation is appropriate. 

What Remains Unclear

Significant questions still remain unanswered. When asked by reporters to specify what data and patterns USCIS used to identify potentially fraudulent cases, Director Edlow restated that the agency looks for "fraudulent patterns" in filed petitions and applications. This lack of transparency makes it all the more difficult for those who are entitled to immigration benefits to ensure that their applications comply with USCIS requirements and are not inadvertently identified as fraud. 

It is also unclear what cities could be targeted next. During the press conference, Director Edlow did not identify other cities that USCIS will investigate for fraud. Rather, he simply declared that "any city should be prepared." 

The Impact of Operation Twin Shield on the Immigration System 

USCIS's recent announcement obscures the fact that the agency receives millions of immigration applications and petitions each year. In one metropolitan area, over the course of ten days, USCIS found fewer than 1,000 cases warranting investigation and confirmed fraud indicators in 275 cases. While any instance of fraud should be taken seriously, USCIS's "declaration of war" paints a misleading picture of an immigration system overrun with fraudulent criminals. This narrative is not only inaccurate, but also harmful to the millions of people who rely on the immigration system for legitimate reasons -- to reunite with family, to contribute to the U.S. workforce and economy, and to seek a better life. 

Operation Twin Shield signals that USCIS is taking a new approach to immigration enforcement, which may include the following: 

• Increased site visits and in-person interviews
• Greater scrutiny of marriage-based and employment-based petitions
• Potential reopening of previously approved cases
• Enhanced cooperation between USCIS and other federal law enforcement agencies
