The Portuguese defender signed a three-year deal with the Hoops on Friday after being released by Champions League winners Chelsea at the end of last season.
The 29-year-old, who is QPR boss Mark Hughes’ eighth summer signing, spent four seasons at Stamford Bridge after moving to west London from Porto in 2008.
“I’m really pleased to be here,” Bosingwa told QPR’s website. “I had the pick of many clubs, but the project here excites me greatly.
“I spoke yesterday with the manager and owner and they showed me what they want for the future of the club.”
Hughes expressed his delight at landing the Portugal international – and hopes he can bring some more experience to his side as QPR look to cement their Premier League status.
“José has a lot of versatility which is something I like my players to have,” said Hughes. “He can operate right across the back and can also play the holding role in midfield.
“He’s another Champions League winner, the third in the squad now with Ji-Sung Park and Djibril Cisse, and will add invaluable experience to the group.
“His experience is really important to us. He understands the Premier League and he understands what it takes to win games. He has got a winning mentality and that is what I want to have around the place.”
Bosingwa, who also won the Champions League with Porto in 2004, admitted he was looking to stay in the Premier League following his release by Chelsea.
“I played for Chelsea for four years and I love Premier League football and the supporters,” he continued. It is fantastic for me to stay in England. I’m happy and all of my family are happy, and that is most important.
“This is maybe the most important challenge of my career. I want to help my team-mates and the team with my experience.
“Now I am a QPR player, I will give my best – for the team and for the supporters.
“All together, we will fight for the club. We need time. We start now and in one, two or three years we can win something. We have to have passion and I think the results will come.”
