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 Ukraine
The President of Ukraine (, "Prezydent Ukrayiny") is the Ukrainian head of state. The president represents the nation in international relations, administers the foreign political activity of the state, conducts negotiations and concludes international treaties. The president is directly elected by the citizens of Ukraine for a five-year term of office (whether the presidential election is early or scheduled), limited to two terms consecutively.
