What requirement must players with multiple nationalities fulfill to represent a different national team?

Players with multiple nationalities must obtain written certification from their other national federations to represent a different national team. This requirement ensures that the national federations are aware of and agree to the player's decision to switch allegiance, maintaining proper governance and integrity within the sport. It is crucial to prevent conflicts between national teams and to uphold the rules regarding player eligibility in international competitions.

The necessity of this certification is rooted in FIBA's commitment to ensuring that representation is clear and agreed upon by all parties involved, thereby preventing any potential disputes that could arise from a player switching national allegiances without the necessary approvals.
