What is involved the security clearance process?
The clearance process considers such factors as registration for the Selective Service, failure to repay U.S. Government-guaranteed student loan, credit history, violations of the law, drug or alcohol abuse, or a less-than-honorable discharge from the armed forces. Background investigations may take several months (longer if a candidate has moved frequently or lived overseas for extended periods of time), and may include interviews of supervisors and coworkers. These investigations are conducted by the Department of State in cooperation with other federal, state, and local agencies.
