Q. I entered federal service as a 1811 in 2001. I will reach 20 years of service in 2021 and would like to retire (at 20 years), but I will only be 46 years old. Can I retire with partial retirement and then, upon reaching age 52, receive full retirement benefits? OR am I required to have 20 years and minimum retirement age? I am confused as to when I can retire as an 1811.
