Depending on the sport, nation, and era in question, membership on the national team may be earned through individual play (as is the case for an
Olympic athletics team or a
Davis Cup team), players may be selected by a managers and coaches appointed by a
national sport association, or a team may have to win a national championship in order to receive the right to represent their nation (as in the
World Curling Championships).
Eligibility Various rules are used to determine who is eligible to play for which national team. ====
Association football==== Under
FIFA regulations, a player primarily qualifies for a national team by "holding a permanent nationality that is not dependent on residence in a certain country"—i.e., being a passport-carrying citizen of said country. If a player's single nationality enables him or her to play for more than one FIFA member, any of the following will be sufficient to establish eligibility for a specific association under that nationality: • Birth "on the territory governed by the relevant association." • The birth of a biological parent or
grandparent in said territory. • Two years of continuous residence in said territory at the time of their first appearance. However, FIFA allows associations that share a common nationality to make an agreement among themselves, subject to FIFA approval, by which the residency criterion is deleted completely or amended to require a longer time limit. • Birth in that country. • Birth of a biological parent or grandparent in that country. • Five years of residence in that country after turning age 18. This last rule is intended to prevent associations from naturalising players who lack birth or familial ties in that country, and immediately fielding them in international matches. FIFA will issue waivers to this last requirement if an association can show to FIFA's satisfaction that the player had significant ties to that country prior to naturalisation. A recent example of such a waiver is that of
Gedion Zelalem, a German-born player of Ethiopian descent who has represented the U.S. at under-23 level. He emigrated with his father to the U.S. at age 9 in 2006, and left the country at age 16 to join
Arsenal's youth academy. In 2014, he automatically became a U.S. citizen
outside the normal naturalisation process when his father became a U.S. citizen, and the
United States Soccer Federation applied for a waiver of the adult residency requirement, citing Zelalem's extended childhood residence in the U.S. He was approved to play for the U.S. several months later. Separate from the above rules, a player who holds multiple nationalities may petition FIFA for a one-time change of nationality if they have never appeared in an official
senior international match for any country, and holds the nationality of the second country prior to appearing for said country. The aforementioned Zelalem case falls within the scope of these rules, since he had played for Germany at youth level. ====
Basketball====
FIBA's national team eligibility rules are broadly similar to those of FIFA. Holding nationality is mandatory (but not sufficient) for eligibility to represent a country. Players with multiple nationalities may choose to play for one of those countries at any age by making a written request to FIBA. However, if the player has yet to make a choice and one of those countries formally calls the player to international duty after they reach age 18, that player is required to make a choice at that time. As in association football, playing in an international friendly cannot tie a player to any country; only participation in an official FIBA competition is sufficient for this purpose. Unlike association football, FIBA does not have a "grandparent rule" for most players. The method by which a player obtains citizenship is irrelevant to national team eligibility, as long as it has been legally acquired. The only use of the grandparent rule is to determine a player's eligibility to represent the national team of a country's dependent territory, with two notable examples being those of
Puerto Rico and the
US Virgin Islands, both
US insular areas with their own national federations, and whose native-born residents are US citizens by birth. While the method by which a player becomes a citizen does not affect their eligibility for a national team, it can affect the player's ability to participate in a given FIBA competition. FIBA mandates that in official competitions, no national team can have more than one player on its roster who acquired citizenship by any means after reaching age 16. This also applies to individuals who had the right to a second nationality at birth (such as individuals born in
Northern Ireland, who are generally born with
UK citizenship but also
have the right to citizenship in the
Republic of Ireland from birth), but did not exercise that right until age 16 or later. ====
Baseball==== While eligibility rules may differ in some small details from
WBSC rules, The eligibility rules of
World Baseball Classic provide a very similar qualifying criteria, as follows: • Citizenship of the nation the player represents. • Holding a passport of the nation the player represents • Holding a permanent legal resident of the nation the player represents. • Being born in the nation the player represents. • One of the Parents being citizen in the nation the player represents. • One of the Parents being born in the nation the player represents ====
Cricket==== The eligibility rules of the
International Cricket Council provide three qualifying criteria for prospective national team players, all linked to the country governed by a specific national federation: • Birth. • Nationality, defined as holding a valid passport. • Three years of permanent residence. Players can only be tied to a given national team by being named to that country's squad, either in the first XI or as a substitute (playing or non-playing), in an official ICC match—defined as a
Test,
ODI, or
Twenty20 match that involves a national federation's senior side. Playing at under-19 level, or for a senior developmental team, does not bind an individual to that country. Unlike many sports, which make changes of nationality difficult or impossible, cricket allows players to represent more than one country during their careers. However, a player is limited to representing two countries in their lifetime, and a three-year stand-down period is enforced—unless the player who has previously represented an ICC associate member is seeking to play for an ICC full member (i.e., a Test-playing nation), in which case there is no stand-down period. The player may represent their original country after representing the second country, but only after the full three-year stand-down period. • Birth in the country. • Having a parent or grandparent born in that country. Note that unlike FIFA, which defines "parent" and "grandparent" to include only blood relations, World Rugby replaces blood relations with adoptive relations if the player has been legally adopted under the laws of the relevant country. This replacement also applies if the player was not adopted, but one or both of the birth parents had been adopted. • Residing in the country for a set period of time prior to their first appearance for that country. The required period was most recently expanded from three years to five years effective 31 December 2020. The five-year rule affects players who moved to a new country after 31 December 2017 and cannot qualify by another method. • Completion of 10 years of cumulative residency in the country, regardless of whether any of the other criteria have been met. This particular criterion went into effect in May 2017. This does not prevent a national union from requiring that its representative players hold that country's nationality. For example, since December 2016, the
French Rugby Federation has required
French nationality as a precondition for national team selection, with players who had represented France before the policy change exempt from said requirement. Through 2021, if a player has ever played for one national team then they may not play for the team of a different nation at same or at the next-higher level of seniority. However, the addition of rugby sevens to the
Olympics created a loophole due to the
IOC's different eligibility criteria. Players who had been "captured" by one country but held the passport of another country could make a one-time change of allegiance to the second country under the following conditions: • A 36-month "stand-down" period from any international rugby is enforced. • The player must have a birthright connection to the new country—either by the player's own birth, or that of a parent or grandparent. (The rule that replaces biological parents with adoptive parents remains in force.) • Also, the change of nationality must be approved by World Rugby. As for the concept of "capturing"—i.e., being tied to a specific country—the criteria have evolved over the years. Under current World Rugby regulations, a player is captured once they play for one of three specific teams: ==See also==
