The Canaries have completed a temporary deal for the Sierra Leone international, further boosting a forward line already strengthened by Luciano Becchio's recent arrival
The completion of the deal for the 28-year-old means he becomes the second striking option to arrive at the club in the past week following Luciano Becchio’s move from Championship side Leeds United.
Kamara boasts an impressive goalscoring record in the MLS, having netted 31 times in 98 appearances, and joins Norwich until May 6.
After finally completing his move, the Sierra Leone international tweeted: “Happy to say I have picked up my passport/visa & getting on a flight tonite to England. Gonna miss my #SkcNation. Hold it Down boys c u soon."
Speaking on January 31, when the formalities of the move had largely been finalised, Canaries manger Chris Hughton revealed his delight.
He told BBC Radio Norfolk: "I'm delighted to bring Kei to the football club, he has been one of Major League Soccer's best players over the last few seasons.
"There's no doubt it's a big jump to make into the Premier League. It is an exciting challenge both for him and us here at the club to prove his talent.
"Kei also adds some valuable competition upfront alongside the current striking options we have here at the club.
"I don't think it's about the league they play in. We would always have to have good reasons for liking a particular player.”
Norwich failed in their attempts to bring Celtic forward Gary Hooper to the club in January, whilst they were also heavily linked with a move for Sporting Lisbon striker Ricky van Wolfswinkel.
