Military & Contractor Clearance Information

Visits by U.S. industry and military personnel to the Ministry of Defence (MOD) Headquarters Buildings, DSTL, QinetiQ, and MOD (PE) Contractor Sites must process a clearance request with the U.S. Embassy.

This page will provide an overview of the clearance request process and state where more detailed information may be obtained.

The Process (Industry)

  1. Obtain a clearance request form from the U.S. Defense Security Service (DSS).
    Contact information:        Phone:  +1 614-827-1650 / Fax:    +1 614-827-1651
  2. Submit the completed request to DSS in Columbus, Ohio. The DSS will verify your information and pass the form on to the ODC London.
  3. The ODC will process the form and pass it on to the British International Visit Clearance Office (IVCO) for final approval. IVCO is responsible for all visits by U.K. Nationals to military and defence contractors sites overseas, and for the visits by all foreign nationals to U.K. military and defence contractors sites.
  4. IVCO awards the clearance.

The Process (Military and DoD Civilians)

  1. Coordinate details of visit (date, times, locations, poc’s) with host.
  2. Complete the Country Clearance Request (CCR) in accordance with the Foreign Clearance Guide (FCG).
  3. Send the CCR information to the Defense Attache Office (DAO), the Office of Defense Cooperation (ODC) London U.K. no later than 30 days before the visit.
  4. DAO processes the form and passes it on to the British International Visit Clearance Office (IVCO) for final approval. IVCO is the British department responsible for all visits by U.K. nationals to Military and defence contractors sites overseas, and for the visits by all foreign nationals to U.K. military and defence contractors sites.

Note: Except for Blanket Agreements, once you have sent your material to DAO you may assume everything checks out unless notified.
However, it is important to follow-up with your POCs to ensure there were no problems with the request.

Most Common Reasons for Rejected Foreign Clearance Requests (Military and DoD Civilians)

  • Failure to provide DAO with detailed location information.
  • Failure to meet time requirement for submitting clearance request (23 days is the limit, 30 is preferred).
  • Failure to include U.S. security clearance information in clearance request.
  • Failure to provide the purpose of the visit, the program, and classification of the meetings.
  • Improperly assuming a Blanket Clearance eliminates the need for a specific clearance request for follow on visits. Once approved, BCR allows you to omit subsequent traveler clearance information on a specific clearance request (however, a specific clearance is required).
