The application form (SF-86) (Questionnaire for National Security Positions), requires personal identifying data, as well as information regarding citizenship, residence, education, and employment history; family and associates, and foreign connections/travel. Additionally, it asks for information about criminal records, illegal drug involvement, financial delinquencies, certain types of mental health treatment, alcohol-related incidents and counseling, military service, prior clearances and investigations, civil court actions, misuse of computer systems, and subversive activities. The number of years of information required on the form varies from question to question—many require 7 years, some require 10 years, and others are not limited to any period of time.
