Nasr scored Sauber's only points of the season last time out in Brazil and says that remaining with the Swiss team for a third season is a "priority".
"There are still negotiations going on, talks with Sauber mainly. That’s our priority now," he said.
"I have a great relationship with the team, it’s been two great years. We saw the two sides of the coin; the first year I had in Formula One we were able to achieve so much. The second, we had such a difficult time with the car being uncompetitive, but it was nice that we were able to get those two points in Brazil. I’m sure that has given a boost to the team."
"As I said, these two points mean a lot to myself and to the team and hopefully we’ll know it [2017 destination] soon."
