Twenty-five years after the September 11 attacks, a Breitbart News report is drawing fresh attention to a long-standing immigration vulnerability: the visa overstay loophole. According to the outlet, seven of the 19 hijackers who carried out the attacks had overstayed their visas either in the period before September 11, 2001, or at the time of the attacks themselves.
All 19 terrorists entered the United States lawfully, Breitbart reported, typically by deceiving immigration authorities about previous travel to the U.S. Four of them were flagged with what the report describes as “suspicious indicators” on their visa applications or passports when they were admitted. Sixteen obtained tourist visas, while the remaining three held business or student visas.
The Breitbart report arrives as the Department of Homeland Security releases its most recent figures on visa overstays, which show that nearly half a million foreign nationals remained in the United States after their visas expired in fiscal year 2024. The department’s overstay report also noted that thousands of nationals from Saudi Arabia, Egypt, the United Arab Emirates, and Lebanon — the countries of origin for the 9/11 hijackers — were among those who overstayed.
A Pattern That Predates the Attacks
September 11, 2001 remains the deadliest terrorist attack on American soil. Hijackers flew two commercial planes into the Twin Towers of the World Trade Center in Lower Manhattan and a third into the Pentagon in Washington, D.C. A fourth plane, United Airlines Flight 93, crashed in an empty field near Shanksville, Pennsylvania, after passengers attempted to retake the cockpit; the 9/11 Commission concluded the hijackers had intended to strike the U.S. Capitol Building.
The attacks killed 2,977 people, and countless others have since died from illnesses linked to exposure at the crash sites.
Breitbart’s reporting situates those deaths within a policy debate that has persisted for a quarter-century. The hijackers did not slip across a border undetected; they presented themselves at consulates and ports of entry, received visas, and were admitted. For seven of them, the failure came later — when they remained in the country after their authorized stays expired.
The overstay issue has long been a point of contention in Washington. Enforcement of visa expiration dates has historically received less attention and fewer resources than border crossings, even though DHS overstay reports have consistently shown that hundreds of thousands of people remain in the country unlawfully each year after entering legally.
What the Latest DHS Numbers Show
The fiscal year 2024 overstay report cited by Breitbart puts the total at almost 500,000 foreign nationals who stayed past their visa terms. The report also breaks down overstays by nationality, and the inclusion of significant numbers from Saudi Arabia, Egypt, the United Arab Emirates, and Lebanon gives the figures a particular resonance given the origins of the 9/11 attackers.
Since the attacks, Congress and multiple administrations have enacted a series of immigration security measures, including the creation of the National Counterterrorism Center, tightened screening procedures for visa applicants, and the collection of biometric data at entry points. The persistence of large-scale visa overstays, however, suggests that the challenge of tracking people after they are admitted has not been fully resolved.
Breitbart’s report frames the overstay loophole as an ongoing vulnerability rather than a historical footnote. The outlet notes that the hijackers who overstayed did so either before the attacks or at the time they were carried out, underscoring that the system’s failure to flag their expired status did not prevent the plot from proceeding.
The report does not name the seven individuals who overstayed, nor does it specify how long each remained past their authorized period. It also does not indicate whether any of them were subject to removal proceedings before the attacks.
A Debate That Has Not Gone Away
Immigration policy remains one of the most polarized issues in American politics, and the 9/11 anniversary routinely prompts renewed scrutiny of security gaps. Advocates for stricter enforcement point to cases like the hijackers’ overstays as evidence that legal entry alone does not guarantee that someone will comply with the terms of their admission. Critics of aggressive enforcement, meanwhile, caution against treating the 9/11 attackers as representative of the millions of people who enter the country lawfully each year.
The DHS overstay report cited by Breitbart does not draw a direct line between the fiscal year 2024 figures and terrorism. It simply documents the scale of the phenomenon: hundreds of thousands of people who arrived legally and then stayed.
For the families of the 2,977 victims, and for the first responders and survivors still dealing with the health consequences of that day, the policy questions carry a weight that statistics alone cannot capture. Breitbart’s report is a reminder that one of the mechanisms the hijackers used to remain in the country — the simple act of not leaving when a visa expires — is still in use today.
