Irving was born in Australia in 1992, while his father was playing professional basketball in Melbourne. He holds dual U.S. and Australian citizenship, making him eligible to play for either country under FIBA rules.
Irving said Monday night, after Cleveland lost to Utah 109-100, that he will remain with Team USA. He hopes to make the Olympic team in 2016 and play again for Duke coach Mike Krzyzewski.
Irving said he received confirmation that Krzyzewski will coach Team USA in four years in the Rio Olympics. Irving played for Krzyzewski at Duke last season before becoming the No. 1 pick in the NBA draft.
"It was the right decision," said Irving, who has represented the United States in junior competition. "I found out Coach K would be coaching in 2016. It made my decision so much easier to play for my coach again. That was the deciding factor."
However, team USA chairman Jerry Colangelo told ESPN.com's Marc Stein on Monday night that the subject of who will coach the team in 2016 has not been "discussed at all."
Krzyzewski said Tuesday he has not discussed any role with USA Basketball beyond the 2012 Olympics.
"While Kyrie and I have discussed his potential role with USA Basketball in the future, my focus right now is on the remainder of our Duke team's season and the 2012 Olympics," Krzyzewski said. "Jerry Colangelo and I have not discussed anything beyond what is ahead of the USA National Team this summer as we pursue a gold medal in London."
Colangelo echoed Krzyzewski, saying Tuesday there has been no talk beyond 2012.
"There's been no discussion about roles beyond this summer, and it would be premature to do so," Colangelo said. "Kyrie is an exciting player who is on our radar and while it is impossible to forecast what will happen in the next couple of summers, I'm sure if he continues to play at the level he is playing at now he will be given serious consideration for future USA Basketball teams."
Irving, who will turn 20 on March 23, is the top contender for NBA rookie of the year honors. He leads rookies with 18.6 points per game and is second to Minnesota's Ricky Rubio with 5.1 assists.
Irving, the centerpiece of the Cavaliers' rebuilding project, is shooting 48.3 percent from the field. He was the MVP of the Rising Stars Challenge during NBA All-Star Weekend.
