Export Control Considerations When Foreign Visitors Enter Company Facilities

Introduction

Hosting international customers, suppliers, researchers, and business partners is routine for many companies. Facility tours, technical demonstrations, audits, and collaborative meetings are often essential to maintaining global business relationships. However, allowing a foreign person to enter a controlled workspace can create an export — even if nothing physical leaves the building.

Under U.S. export regulations, providing access to controlled technical data or defense services to a non-U.S. person inside the United States may be treated as a “deemed export.” Agencies such as the Bureau of Industry and Security and the Directorate of Defense Trade Controls expect companies to evaluate and manage visitor access before the visit occurs.

Companies that prepare structured visitor procedures can support business development while preventing unauthorized disclosures and enforcement risk.

Why Visitors Create Export Risk

A visitor does not need to receive documents or files to trigger export concerns. Visual inspection of equipment, overheard technical conversations, whiteboard drawings, or photographs of manufacturing processes may all constitute a release of controlled technical data.

Many violations occur because organizations treat tours as administrative events rather than controlled technology access. Reception desks, conference rooms, engineering floors, and production areas all present different levels of exposure. Export compliance therefore begins with planning — not with the visitor badge.

Key Controls for Managing Foreign Visitors

1. Advance Screening and Approval

Companies should require pre-approval for all foreign national visitors. The review should include:

• Visitor nationality and employer
• Purpose of visit
• Areas requested for access
• Topics to be discussed

Compliance personnel can determine whether licensing requirements apply or whether access must be limited. Screening should also include restricted party list checks before confirming the visit.

2. Technology Control Plans and Escorting

Facilities handling controlled technology should operate under a Technology Control Plan (TCP). For visitors, this typically requires:

• Continuous escort by trained personnel
• Restricting movement to approved areas
• Preventing unsupervised wandering

Escorts should understand they are responsible for monitoring conversations - not merely guiding directions. An escort’s role is compliance supervision, not hospitality.

3. Managing Visual and Verbal Disclosures

Many disclosures occur informally. Employees may attempt to be helpful and accidentally share controlled details. Companies should brief employees in advance regarding:

• Topics that cannot be discussed
• Equipment that cannot be demonstrated
• Prohibition on answering technical questions beyond approved scope

Conference rooms should be cleared of drawings, prototypes, and screens displaying technical data before meetings begin.

4. Electronic Device and Photography Restrictions

Personal electronics can capture sensitive information instantly. Policies should address:

• Camera and phone restrictions
• Removal of recording devices in secure areas
• Temporary storage lockers if necessary

Additionally, visitors should not be provided unrestricted Wi-Fi or network access, which could allow viewing or downloading controlled data.

5. Documentation and Recordkeeping

Companies should maintain records demonstrating compliance, including:

• Visitor request forms
• Screening results
• Signed nondisclosure agreements
• Escort logs and visit agendas

These records help show regulators that the company took preventive measures rather than relying on informal awareness.

Training Employees Before the Visit

Even well-designed procedures fail if employees are unaware of them. Prior to scheduled visits, companies should notify affected teams about:

• Visitor identity and affiliation
• Approved discussion topics
• Restricted areas and technologies

Short pre-visit briefings significantly reduce accidental disclosures. Employees often assume compliance is handled by security staff, when in reality conversations pose the greatest risk.

Conclusion

Foreign visitors present valuable business opportunities but also real export control exposure. A facility tour can unintentionally become an unauthorized export if sensitive technical data is seen, discussed, or captured. By implementing advance screening, escort procedures, communication controls, electronic device restrictions, and thorough documentation, companies can confidently host international partners while protecting regulated technology.

Effective visitor management is ultimately about awareness and preparation. When employees understand that access — not just shipment — triggers export rules, organizations can maintain open global collaboration without sacrificing compliance or security.
