What are Fifa's rules on switching nationalities?

[BBC] Fifa's rules allow a player to switch the nation they represent for a number of reasons. Inter Milan striker Ange-Yoan Bonny is among the latest players to officially switch nations, transferring from France to Ivory Coast ahead of this summer's World Cup. Ivory Coast are competing at the tournament, meaning Bonny could feature if called up to the squad.

In order to do so, players must be eligible to play for the nation they are switching to. There are five different sets of circumstances in which a player is eligible to switch nations. A new rule introduced in 2021 allowed players who had played up to three senior international caps prior to the age of 21 to switch nations.

Previously, the rule stated that players could not switch nations once they had earned a senior cap in a competitive match. England midfielder Declan Rice benefited from this rule when switching from the Republic of Ireland. Rice won three senior caps for the Republic, all of which came in international friendlies, before opting to instead play for England in 2019.

Former Chelsea striker Diego Costa also swapped nations to Spain in 2014, having played for Brazil in two friendly matches in 2013. How can a player switch nationalities?
