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 India
Under The Presidential and Vice-Presidential Elections Act, 1952, a candidate to be nominated for the office of president needs 50 electors as proposers and 50 electors as seconders for his name to appear on the ballot.
Article 56(1) of the constitution provides that the president shall hold office
for a term of five years from the date on which he enters upon his office. According to Article 62, an election to fill a vacancy caused by the expiration
of the term of office of President shall be completed before the expiration of the term. An election to fill a vacancy in the office of President occurring by reason of
his death, resignation or removal, or otherwise shall be held as soon as possible
after, and in no case later than six months from, the date of occurrence of the vacancy; and the person elected to fill the vacancy shall, subject to the provisions of Article 56, be entitled to hold office for the full term of five years from the date on which he enters upon his office. To meet the contingency of an election to the office of President not being completed in time due to unforeseen circumstances like countermanding of election
due to death of a candidate or on account of postponement of the poll for any valid
reason, Article 56(1)(c) provides that the president shall, notwithstanding the
expiration of his term, continue to hold office until his successor enters upon his office.
