Can a player choose a national team of a country they transferred from before they turn twenty-one?

A player who has transferred from one country to another must adhere to specific eligibility rules regarding their national team representation before they turn twenty-one. According to these eligibility rules set by FIBA, a player is generally allowed to represent the country of their transfer until they reach the age of twenty-one. This means that once they have transferred to a new country, they are bound to represent that nation until they reach the age threshold.

After turning twenty-one, the player may have more flexibility in choosing to represent a different national team, depending on other factors such as their residency and the laws governing eligibility. However, prior to that age, the player does not have the freedom to switch national teams freely or represent a country they previously left. This rule is intended to maintain a level of stability and fairness in international basketball competitions.

This aligns with the broader context of FIBA's regulations, which necessitate that players commit to a national team representative structure that fosters competitive integrity and national loyalty during their earlier developmental years.
