Clearance
What is an SF-86?
The Questionnaire for National Security Positions. Almost every Guardian job needs a clearance.
SF-86 is the long federal form used to start a security clearance. It asks about where you lived, worked, went to school, foreign contacts, finances, drugs, and police history. Start gathering addresses and dates now. Lying on it is worse than an ugly fact. Your recruiter and the investigation contractor will compare it to records.
