What is the length of time a representative can serve?

There are no term limits for Members of the House of Representatives or the Senate, so members of both can be elected as many times as they can. However, a term in the House of Reps. is two years. All 435 members of the House of Reps. are up for election every two years. Senate terms are six years, with roughly 1/3 up for re-election every two years.
