The 32-year-old, who signed for Spurs from West Ham in August 2011, is set to be reunited with former manager Harry Redknapp at Loftus Road
The 32-year-old is facing stiff competition for a starting berth at White Hart Lane this term following the signing of Paulinho, while the arrival of Etienne Capoue from Toulouse is also set to be completed before the end of the transfer window.
However, Redknapp, who signed Parker from West Ham when he was in charge at Tottenham, is keen to have the England international with him at Loftus Road as QPR aim to win promotion back to the Premier League at the first attempt.
"We're hopeful of getting Scotty signed soon," Redknapp said.
"He's a great lad and will be a really good signing for us."
