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.
Legislative session
The US Congress is renewed every two years as required by the US Constitution, with all members of the House of Representatives up for reelection and one-third of the members of the US Senate up for reelection. (Senators serve a six-year term; House members serve a two-year term). Each Congress sits in two sessions lasting approximately one year. Thus, the 1st session of the 114th Congress commenced on January 3, 2015 and the 2nd session commenced on January 3, 2016, with the same members and no intervening election. All legislative business, however, is cleared at the end of each session. It is common for bills to be reintroduced in the second session that were not passed in the first session, and the restrictions on reconsideration only apply to a single session.
