Frequently Asked Questions
Which military members have a security clearance?
Military security clearances are required for military members whose roles involve access to classified information. This includes personnel in intelligence, special operations, cybersecurity and certain command positions. Clearances range up to Top Secret, with some roles requiring additional levels of access such as Sensitive Compartmented Information (SCI) or Special Access Programs (SAP).
How successful are security clearance appeals?
This varies widely depending on the specifics of your case, including the nature of the disqualifying issues and the strength of the mitigating evidence presented. Appeals that effectively address the concerns in the Statement of Reasons (SOR) and provide strong mitigating evidence tend to have a higher likelihood of success.
How long does a security clearance appeal take?
The timeline of security clearance appeals can vary, but it generally takes several months to a year to complete. Factors impacting this timeline involve the complexity of the case, the workload of the adjudicating agency, and the thoroughness of the submitted appeal documentation. Additional hearings or further investigations can extend the process.
What disqualifies someone from acquiring a military security clearance?
Many factors can disqualify someone from acquiring a military security clearance. This may include a history of criminal activity, substance abuse, foreign influence or dishonesty during the clearance process. Any behavior that suggests unreliability or a risk to national security can be grounds for disqualification.
