Students tentatively selected for the internship program must undergo a background investigation and receive the appropriate security determination, typically either a Secret or Top Secret security clearance. The clearance process takes approximately 60-120 days to complete from the time you submit your forms to the Bureau of Diplomatic Security (DS). Investigations may take substantially longer than 120 if there is a security, suitability, or medical issue to resolve. In part, these issues could include current or past illegal drug use, to include marijuana, or alcohol abuse, criminal conduct, or a recent history of financial/credit problems.  For more information, visit https://www.state.gov/security-clearances.
