Many other internship possibilities also exist. Some of these are paid, many are unpaid. Most are in headquarters operations of IC agencies in the vicinity of Washington, D.C., but some are in other locations, including overseas. The typical application process begins with an on-line application through an IC agency website. Many internships are geared to the academic year and the student works during the summer but some opportunities also exist during the fall and spring semesters. Because of the lengthy background check process required for some internship programs, students must carefully adhere to agency deadlines. For example, summer internships may require applications to be submitted by mid October or November 1st.
