To be elected to the United States Congress, you must win the popular vote in your constituency or state. But, before you can run for office, you must meet certain eligibility requirements. You must live in the state, or constituency within the state, that you wish to represent, you must be at least 25 years old and you must be a U.S. citizen.
Natural Born Not Required
Unlike the U.S. President, who must be a natural born citizen to be eligible for office, you can be elected to Congress even if you were born outside of the United States. The Constitution requires you to be a citizen for at least seven years to be eligible for a seat in the House or the Senate.
