The 30-year-old Senegal striker took advantage of Cottagers boss Mark Hughes' striker injury problems at the weekend by hitting a treble against League One Peterborough to help the side clinch a 6-2 win and book an FA Cup fourth round home tie against London rivals Tottenham.
However Kamara's current deal at Craven Cottage is due to expire at the end of the season which could see him sign a pre-contract agreement with a side outside of England and leave on a Bosman free transfer in the summer.
Despite the uncertainty, Kamara insists he is just looking to make the most of his latest chance in the first XI and he hopes to stay there when the likes of Bobby Zamora, Andrew Johnson and Mossa Dembele are all back fit and fighting for selection in Hughes' attack.
"I've got a contract until the end of the season and at the moment, when I get my chance on the pitch, I'm always trying to do my best," the former Senegal striker said.
"We'll see what happens in the next few matches. This is not my problem, I'm just focused on Fulham. I'm not concerned that my contract is ending."
He added: "In February, I think Bobby Zamora is coming back and Moussa Dembele. We have other strikers coming back so the competition makes it better for us. Competition is good for the club.
"When you are player and you don't play you are obviously a little bit frustrated but this is all part of the game."
