Answer:
It depends on what role we are talking about.
Step-by-step explanation:
The president of the United States is elected indirectly through the United States Electoral College to a four-year term, with a term limit of two terms (totaling eight years) or a maximum of ten years if the president acted as president for two years or less in a term where another was elected as president, imposed by the Twenty-second Amendment to the United States Constitution, ratified in 1951.
The Vice President also serves four-year terms but without any term limit.
U.S. Representatives serve two-year terms.
U.S. Senators are elected to six-year terms, and every two years the members of one class—approximately one-third of the senators—face election or reelection.
Federal judges have different terms in office indeed. Article I judges; such as those that sit on the United States bankruptcy courts, United States Tax Court, and United States Court of Appeals for the Armed Forces, and certain other federal courts and other forms of adjudicative bodies serve limited terms: The Court of Appeals for the Armed Forces for 15 years, bankruptcy courts for 14. However, the majority of the federal judiciary, Article III judges (such as those of the Supreme Court, courts of appeal, and federal district courts), serve for life.
