The President of the United States serves a four-year term, and can be reelected once.

Length is the main difference between a Senator's term and a Representative's term. Members of the House are elected by the voters to serve 2-year terms, while Senators are elected to serve 6-year terms.

In the USA, a member of the House of Representatives has to run for re-election, or step down if he/she so chooses, every two years. They have a two year term. Senators, on the other hand, have a 6 year term. Neither Senators nor Representatives are limited as to how many terms they may serve.

It's not a question, but I'll answer it anyway. The time an elected official stays in office is determined by the term length of the office, which varies from one government to another, the number of times the person is elected, and if/when the person is forced out of office, due to death, term limit if any, etc., or resigns. A person cannot be elected U. S. President more than twice, and a person who has served at least two years of a presidential term to which he/she was not elected cannot be elected President more than once.
