Some oriundi have played for the Italian or Spanish national football teams in international competition; among these are some who had previously represented their native country. FIFA requires international footballers to have either citizenship of a country or close ancestral ties to it. Oriundi may qualify under the latter heading; in addition, they can acquire citizenship more easily than immigrants not of native extraction, owing to jus sanguinis. When the Italian and Spanish Leagues imposed quotas or bans on "foreign" players, oriundi were partially or totally exempt from these.
Tours by European club sides of Latin America were common from the 1920s to the 1950s; tours in the reverse direction also occurred. European managers often recruited Latin Americans they had seen playing on these tours. The recruitment of dual internationals was greatly reduced by FIFA which ruled in 1964 that a player could not represent more than one country. In the 1960s, with incidents like the Battle of Santiago in 1962 and several finals of the Intercontinental Cup, South American football came to be seen as more violent and defensive, and hence fewer players were recruited.
Italian oriundi 
The Italian Americans who "returned" to Italy in the 1920s and 30s were known as rimpatriati ("repatriated people"). In Fascist Italy they automatically had dual citizenship and had no need to undergo naturalization. Vittorio Pozzo, manager of the national team, selected several for the victorious 1934 World Cup side. He rebutted critics of this policy by saying "if they can die for Italy, they can play for Italy", a reference to conscription. Guaita, Scopelli and Stagnaro tried to leave for France to avoid being called up for the Abyssinian campaign in 1936.
Oriundi as a term in Italian football dates from the early 1950s. The category existed separately from native and foreign players at intervals until the 1970s. Sivori, Maschio, and Angelillo, the three stars of the Argentina team that won the 1957 Copa América were signed by Italian clubs and given citizenship, thereby missing Argentina's disappointing showing at the 1958 World Cup.
In 1966 no new foreigners were admitted to the Italian League. Their presence was blamed for the contued underperfomance of the national side, culminating at the humiliating defeat by North Korea at that year's World Cup. The ban was eased when one foreigner per Serie A team was allowed from 1980.
In recent years, the most famous Italian oriundo has been the former Juventus' Italian Argentine footballer Mauro Camoranesi, who is an Italian citizen due to his grandfather from Marche. Mauro won the 2006 FIFA World Cup with the azzurri.

Italian rugby oriundi 
The number of Argentines playing rugby in Italy has increased since Italy embraced professionalism in 1995, while the Argentine league system remains amateur. (However, professionals, including those based in Europe, are eligible to play for the Argentina national team, and the country's national federation is in the early stages of creating a domestic professional player pool for the national team.) Italian rugby also allows naturalized foreigners. Restrictions on changing nationality are less strict in rugby than in soccer, and three years' residency qualifies. Oriundi capped by the Italy national rugby union team include:
Spanish oriundi 
Few South Americans played football in Spain before World War II. Spain under General Franco allowed for dual nationality with Latin American countries from 1954. Players such as Alfredo Di Stéfano and Héctor Rial quickly transferred, and helped make Real Madrid the dominant club of the early years of the European Cup. In 1962, the Spanish League banned all foreign players, as their presence was blamed for the poor performance of the national team. Oriundi were allowed if they had not been capped by their native country. As a result, clubs were anxious to prove Spanish ancestry for would-be imports, resulting in some dubious cases. Some players obtained forged birth certificates, providing spurious Spanish ancestors. This was easy in Paraguay during the corrupt dictatorship of Alfredo Stroessner. Consequent scandals emerged at various times, including one exposed by FC Barcelona in 1972. In 1973, to reduce the incentive for corruption, up to two non-oriundi foreigners were allowed per team. Nevertheless, the recruiting of Latin American players continued so strong the Argentine FA in preparation for hosting the 1978 World Cup forbade its preliminary squad of 40 from moving abroad, lest they be "poached". Spain reduced the number of oriundi to one per team after another forgery scandal in 1979 From 1979 to 1982, no Argentines were allowed abroad, and many like Mario Kempes returned home.
