The 28-year old has received game time in just two of the past 10 internationals the US has been involved in and is determined to put that right.
Cameron told ESPN that being played out of position at club level has harmed his chances with the national team but he will not let that dampen his spirits in a World Cup year.
"It's been tough with the national team. It's been frustrating," Cameron said.
"I was one of Juergen (Klinsmann)'s mainstays, and then all of a sudden I kind of lost my position because I wasn't playing center back and he wanted to give some other guys experience.
"I wasn't confident in playing right back last year. And with the style we played at Stoke, sometimes in a game I'd touch the ball maybe three or four times. I was just putting in a battle."
The former Houston Dynamo star added: "I told Juergen how I feel, that I'm frustrated because I'm playing week in and week out and then I come [into the national team] and I don't even know where I'm playing or how you're feeling about me as a player.
"He just reassured me that he does value me and my versatility. He said, 'Keep your head up, I know you're disappointed, but you're right there, you're fighting for three positions, and that's a good thing.'"
