The Swimming Federation of India (SFI) is the governing body for the sport of swimming in India. It is responsible for promoting and organizing swimming competitions at various levels, including national and international events, and overseeing the development of the sport in the country.
The headquarters of SFI is based in New Delhi because it is the capital of India, and most national sports federations and governing bodies in India have their offices in New Delhi. This central location allows for better coordination with the Ministry of Youth Affairs and Sports, the Indian Olympic Association, and other related bodies.
The Swimming Federation of India plays an important role in the selection of swimmers for international competitions, including the Olympics and World Championships, and also in the development of swimming infrastructure and talent across the country.
