The 22nd Amendment sets the term limit for election to the office of President of the United States.
The Amendment states that;
<em>"No person shall be elected to the office of the President more than twice and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of President more than once."</em>
