The 30 year-old joined the R's as a free agent from Chelsea last summer and went on to make 23 starts and an appearance from the bench last season, scoring one goal.
But his time at Loftus Road was never smooth. The player was fined two weeks' wages in December after refusing to sit on the bench for a Premier League game against Fulham, before then becoming the subject of the R's fans' jeers over the forthcoming month.
With his time at QPR now officially over, Bosingwa is on the verge of completing a move to Turkish top flight side Trabzonspor.
Bosingwa was greeted at the airport in Turkey by his former Chelsea team-mate Florent Malouda, who recently joined Trabzonspor himself.
