Sandro would welcome the chance to seal a permanent deal with West Brom but is prepared to keep his options open.
The on-loan QPR midfielder is waiting to hear from the club over whether they will keep him.
Albion have an option to make the deal permanent after they signed the Brazil international on loan from Rangers until the end of the season in January.
His agent Luiz Paulo Chignall told Press Association Sport: "I don't know Sandro's future in this moment because we need to wait for West Brom and, maybe, the next window as well. Sandro has just one season more and then he is a free player.
"He likes the atmosphere of West Bromwich, the directors, staff, players and supporters.
"We have three matches yet. I think that after the end of the season the club will contact us."
Sandro has made 11 appearances, six starts, for Tony Pulis' side to help them seal survival in the Premier League. He was a late substitute in Monday's 1-1 draw at Tottenham which derailed his former club's title bid.
The 27-year-old has started three of the Baggies' last five matches but Press Association reported they remain undecided over his future.
Sandro moved to Spurs from Internacional in 2010 and joined QPR in 2014 but is not expected to return to Loftus Road with the club in the Championship.
The Baggies host West Ham on Saturday and are 13th in the table on 41 points but have not won in their last six games.
