Answer:
Lifetime.
Explanation:
Technically there are no requirements to be a SCOTUS judge. The age of the judges has varied between 32 and 68 years of age. They don't have to have been born in the United States either (six judges were born outside the U.S.). In addition, there is no law that requires nominees to be lawyers. However, all judges have studied laws.
Each judge is appointed for life. However, the judges remain in their positions for an average of 16 years. They can also resign or withdraw from the Court whenever they wish.
