The League has also formed a working relationship with the United Soccer Leagues (USL) and will become a member of the United States Soccer Federation (USSF). 

NISL indoor soccer was developed to appeal to sports fans around the world. The fast-paced, fiercely competitive game is played on artificial turf on a hockey-rink-sized field surrounded by dasherboards and Plexiglas with eight-foot high by 14-foot wide goals receded into the end boards. Creative dribbling, pinpoint passing, acrobatic goalkeeping and rugged defensive play are all skills demonstrated by NISL players. A typical NISL game features end-to-end-action resulting in approximately 60 shots and 11 goals per game. Each game includes four 15-minute quarters and will feature multi-point scoring in which all goals scored will be worth two points, except those goals scored on shot attempts from on or beyond the 45-foot arc surrounding the goal, which will be worth three points. Other unique characteristics of the NISL include action-packed power plays and free substitution of players while play continues.
