Q. I worked for the Department of Justice for 10 years’ 6(c) coverage, and I worked for the Federal Air Marshal Service for almost 11 years, also 6(c) coverage. I also have six years of military service I bought back. I had to leave federal service to take care of my parents. I’m only 46; can I collect a retirement when I turn 50? A. No. You’ll have to wait until you reach your minimum retirement age.
