The Sierra Leone international arrived at Carrow Road on loan from Sporting Kansas City in January - and the MLS side remain unsure if the move will be made permanent
The Sierra Leone international arrived in January on a temporary basis and the current deal is set to expire on May 6, before the end of the Premier League season.
And while the MLS side’s manager and technical director Peter Vermes has revealed a move is in place, he is waiting for the Canaries to confirm the move.
He told reporters: “We're also inquiring as well, so we can do some planning. We're looking into it, but I haven't heard anything yet.
“We've already negotiated everything. Other than Kei saying he doesn't want to do it, it would pretty much go through.”
Vermes believes Norwich could be waiting until they have secured their Premier League status before deciding on a deal for Kamara - who is in his last year of his contract.
He added: “They're not really sure where they sit right now and where they're going to go.
“If they would be a little more secure in their position in the league, I think it would be easier for them to make a deal one way or the other.
“Right now, I think that's why we're not hearing anything. That's my opinion. It may not be fact.”
