Limits the number of times a person can be elected president. Proposed March 21, 1947; ratified February 27, 1951, 3 years and 11 months later. The Twenty-second Amendment to the United States Constitution limits the number of times a person may be elected to the office of President of the United States to two, and sets additional eligibility conditions for presidents who succeed to the unexpired terms of their predecessors. Congress approved the Twenty-second Amendment on March 21, 1947, and submitted it to the state legislatures for ratification. That process was completed on February 27, 1951, when the requisite 36 of the 48 states had ratified the amendment, and its provisions came into force on that date. Wiki link
