Kamara started his first game for Boro on Tuesday following his move from Sporting Kansas on deadline day, and he marked his full debut with a goal in the 2-2 draw with Nottingham Forest.
Kamara is set to make his home bow against Bournemouth on Saturday and he insists that Boro belong in the top flight.
"It's good to be here," said Kamara, who played in the Premier League with Norwich last season.
"It's great to get an opportunity to come to England and play soccer. I'm excited every day to be around the place.
"The excitement in me - I feel like a kid all over again. Middlesbrough is a big club, they've been in the Premier League for years and doing really good things.
"There have been some great players coming through the place so for me to come here and be part of a team that's going to battle to put the club back where it belongs is fantastic.
"When you say Middlesbrough Football Club people expect them to be one of the top teams in the Premier League. When he (my agent) said the name of this club and I was able to speak to the coach, that sold it to me.
"You step into this place that's how you know it's a Premier League calibre club because the training facilities are top class. I'm definitely looking forward to my debut and seeing the stadium.
"I've only been here two weeks or so but seeing the guys around the locker room, after watching one game and being part of another game, I know that we can definitely compete with the other teams in the league."
