In essence, if personnel working for a contractor require access to classified information in the performance of their duties, the contractor must have an FCL and the personnel must have personnel security clearances (PCLs).
If you're interested in finding a job with a company willing to sponsor your security clearance, search defense industry career sites and include terms such as 'clearable' and 'willing to obtain security clearance. ' Some companies are willing to sponsor individuals for security clearance.
Security clearance must be issued before you can begin working. Examples of organizations that require higher tiers of clearance include national security agencies such as the Central Intelligence Agency (CIA) and the Federal Bureau of Investigation (FBI).
Not every position in the military requires a clearance (culinary specialists and some support positions may not), but all officers do obtain a security clearance as a part of their service and all service members undergo a background check and complete some form of security application.
Many people who require security clearance work for the intelligence community, such as intelligence analysts or software administrators. Even custodial staff at top-secret facilities need to have security clearance to perform their duties.
Generally, you cannot apply for a security clearance on your own; you must be sponsored by a government agency or a company with a contract with the government. These entities must determine that your job requires access to classified information.
Only jobs that require a candidate to access classified information and secure facilities require a clearance. However, all federal positions require something called a suitability determination. This is a background investigation that helps the government decide if you are suitable for federal employment.
“Active” Status for Security Clearance A security clearance remains “active” as long as the individual is sponsored by an employer and in a position that requires access to classified information and the background investigation is current.
Security clearances can be issued by many United States Government agencies, including the Department of Defense (DoD), the Department of Homeland Security, the Department of Energy (DoE), the Department of Justice, and the Central Intelligence Agency.
