The Southampton forward is hopeful of the opportunity of regular first team football, with Neil Warnock playing an important role in bringing the player to the club
The forward, who has arrived at Loftus Road from high-flying Championship side Southampton, has experienced top flight football previously in a short spell with relegated Blackpool last season.
And now the 25-year-old is delighted to be back among England's elite following a protracted transfer.
"I am more than delighted that this move has gone through," Puncheon told the club's official website.
"It dragged on over the summer but it's all done now and I am looking forward to getting some minutes on the pitch as and when I can. I am concentrating on getting myself ready for games."
Puncheon also revealed meeting manager Neil Warnock was influential in his decision to join the newly-promoted side, who have signed Joey Barton, Anton Ferdinand, Armand Traore and Luke Young in an attempt to survive their first season back in the Premier League.
"The gaffer played a massive part in me coming to QPR," the former MK Dons man said. "Once I met him and had a chat with him, there was no turning back.
"He has made some great signings, bringing in players who have vast experience in the Premier League. Having them as my team-mates can only help me."
