The former Houston Dynamo star was touted as a possible centre-back mainstay for Juergen Klinsmann but has recently been deployed as more of a defensive midfielder.
With LA Galaxy's Omar Gonzalez and Sporting Kansas City's Matt Besler commanding the central defensive positions, Cameron was sent out to cover the back four in the World Cup qualifying win over Panama on June 12, before starting on the bench against Honduras a week later.
Although he backs himself as a defender, Cameron feels he is capable in a midfield role and simply wants to find his niche in the national team setup.
"It was definitely difficult," Cameron told MLSsoccer.com.
"I was one of his consistent guys playing centre-back, but Omar and Matt have been playing together at centre-back where I'm playing right back, central mid or right mid so I understand why [Klinsmann's] using them.
"I think my two best positions are centre-back and centre mid and I want to be on the pitch for either of them, but it doesn't matter. I just want to be in the starting XI."
And Cameron was also hoping the US, currently top of the CONCACAF hexagonal group after six matches, can kick on and book their ticket to Brazil for the 2014 World Cup.
"You have a deep group of guys playing together and they're developing an understanding of playing with each other. That helps in the games," he added.
"We're sitting on top of the table and probably one more win away from qualifying for the World Cup in Brazil and that's something special."
