The Indonesian national football team is pursuing naturalization processes for several players to strengthen the squad. 

In October 2026, reports indicated that 19-year-old midfielder Demiane Agustien, an Arsenal U-21 player with Dutch birth and Indonesian heritage, was undergoing naturalization. The Football Association of Indonesia (PSSI) is reportedly managing this process to bolster the team for upcoming Asian Cup and World Cup qualifying matches.

By November 2026, Japanese winger Taisei Marukawa joined the national team training camp in Bali. Coach John Herdman requested Marukawa’s presence to evaluate his skills and chemistry with the squad. Marukawa, who has played in Indonesia for five years, is also undergoing the naturalization process to represent the national team.
