The 28-year old Sierra Leone international has been on loan with the Premier League outfit since the end of January but will head back to Sporting Park early this week.
Kamara, who will be eligible for MLS selection this weekend, made 11 appearances for the Canaries scoring one goal.
Kamara was very grateful to the Canaries fans for his stay, posting the following messages on Twitter.
I want to thank the Norwich City organisation for everything they did for me. Not everyone gets to live they dreams, but they gave me mind.— KEI KAMARA (@keikamara) May 5, 2013
