For decades, the United States has depended on noncitizen labor, international students, and offshore contractors to sustain growth in critical sectors such as technology, healthcare, finance, and higher education. These resources have often been presented as essential for filling labor gaps, reducing costs, and fostering innovation.
Yet this heavy reliance carries significant and often underappreciated national security risks that are largely invisible in official economic statistics and policy discussions.
A core problem is the lack of structural transparency. Unlike every other major industry in the U.S. economy, noncitizen labor and related work programs are not classified as a distinct industry under the NAICS system. This statistical invisibility hides the true scale, economic impact, and national security risks of these activities.
When noncitizens — whether working inside the United States or remotely from abroad — are granted access to sensitive systems, personal data, intellectual property, or critical infrastructure, the risks of espionage, intellectual property theft, and system compromise increase substantially. Current vetting processes, which focus mainly on immigration compliance, frequently fall short in addressing ongoing national security threats.
This section examines these risks in detail, drawing on documented cases and observable trends to highlight the scope and urgency of the challenge.
