I'm joining the Airforce in another year after I finish college (BA in Criminal Justice)... How is OSI?

Working as an OSI Special Agent would be great. The OSI has been the Air Force's major investigative service since 1948. You can become an OSI Special Agent as an enlisted member, officer, or civilian. Getting law enforcement officer jobs is becoming more and more competitive. Agencies can be very selective about who they select. Keep your background good. Many applicants are eliminated from consideration due to things they've done in the past.
