PSIs and security clearances are key elements in protecting the security of the United States. PSIs and security clearances are required to counter the threats that may stem from:
Whether a specific incident would be reported promptly to clearance adjudicative personnel, and whether it would then result in an investigation, and possibly a clearance revocation, would depend on a number of factors.
These would include: who is aware of the incident, the seriousness of the incident, whether previous incidents were a matter of concern in the past, and whether the incident relates to areas considered to be of concern for persons holding a security clearance. Incidents that are not immediately investigated may also be noted and explored later when that individual undergoes a routinely scheduled Periodic Reinvestigation. Information relating to the following issues may be considered significant in relation to holding a clearance:
Foreign intelligence services;
Organizations or people who wish to overthrow or undermine the United States government through unconstitutional means, violent acts, or other terrorist group activities;
May be susceptible to pressure or improper influence.
Have been dishonest or demonstrated a lack of integrity that has caused others to doubt their reliability.
