Biseswar made his Kayserispor debut on 8 January 2012, starting the whole game, in a 1–0 loss against Antalyaspor. Three days later on 11 January 2012, he set up a goal for Emir Kujović, who scored a winning goal, in a 1–0 win over Akhisar Belediyespor in the third round of the Turkish Cup. Five days later against Gaziantepspor on 16 January 2012, he set up a goal for Gökhan Ünal to score the first goal of the game, in a 1–1 draw. However, Biseswar suffered an injury that kept him out for the rest of January. He then returned from injury, coming on as a late substitute, as Kayserispor lost 1–0 against Galatasaray on 11 February 2012. It wasn’t until on 7 April 2012 when Biseswar scored his first goals for the side, in a 5–0 win over Ankaragücü. At the end of the 2011–12 season, he went on to make ten appearances and scoring two times in all competitions.
