The 24-year-old, who can also play in midfield, has signed a one-year deal with the Barclays Premier League newcomers. Sao Paulo-born Perone has been on trial with the west London side for the last month, featuring in several pre-season matches.
QPR boss Neil Warnock told his club's official website, www.qpr.co.uk: "Bruno has fitted in very well in the time he has been with us. He did well during pre-season. He has still got lots to learn but when the time comes I am sure we will be able to put him in the team with confidence."
He added: "One of the things he has got to learn is the language. At the moment Ali Faurlin is helping him out."
If the international clearance proves no problem, Perone will join fellow newcomers Jay Bothroyd, Kieron Dyer, Danny Gabbidon, DJ Campbell and Brian Murphy at Loftus Road.
