President of Argentina
Under the 1994 constitutional amendment, the President serves for four years, with a possibility of immediate reelection for one more term. However, unlike the President of the United States, in Argentina, a person may be reelected again after serving for two terms and staying out of office for the following term. So after serving for two consecutive periods, the president is not allowed to run for a third consecutive one, but may return for the two following elections and so on. There is no limit for a person to be a candidate if he or she does not win the elections.
President of the Czech Republic
The term of office of the President is 5 years. A newly elected president will begin the five-year term on the day of taking the official oath. Candidates standing for office must be 40 years of age, and must not have already been elected twice consecutively. Since the only term limit is that no person can be elected more than twice "consecutively", a person may theoretically achieve the presidency "more" than twice. Prospective candidates must either submit petitions with the signatures of 50,000 citizens, or be nominated by 20 deputies or 10 senators.
