Pastor Maldonado has confirmed he is in talks with Williams about a deal for 2013, but also admits "there is a chance" he could go to another team.
The Venezuelan has endured a mixed season so far, stunning the F1 world in Barcelona when he won the Spanish GP from pole before going nine races without making it into the top 10.
He finally broke his scoring drought at the Japanese GP over the weekend as he came from 12th on the grid to finish eight.
Williams are yet to confirm their driver line-up for next season and Maldonado, who has entered into negotiations with the Grove-based squad, has stopped short of committing himself to the team.
"At the moment there is a chance to go to other teams but we are considering remaining here, but it is still too early," he said.
"The team usually confirm their drivers at the end of the season but we are talking, negotiating.
"This is a good family for me I feel really good here, they feel really happy with me but we know how Formula One is, it can change one day from another.
"It is difficult to say, until other teams have confirmed their drivers you never know. It is difficult. I need to keep pushing, doing my job in the team to try and get some points and we will see."
Maldonado's main sponsor PDVSA, but he is quick to point out that his seat at Williams isn't dependent on continued backing from the oil giant.
"PDVSA is a serious company. I've known them for a long time and it is going to be all good I think because we have a contract and they have been always supporting my career in the past," he said.
"In Venezuela everyone is happy to see me in F1. We won one race this year which is amazing for my second year in F1.
"We haven't had the best car but we still managed to win. We are working very hard on the car and, as you know, I have a lot of responsibility in this team because I am the top driver here.
"It is difficult to accept that we miss many points this year, but it is never too late to recover."
