The 24-year-old has struggled to make an impression with the Potters since signing from Club Nacional in a deal worth £2.6million back in 2009 and Tony Pulis has sent him to the League One side on loan.
Arismendi still has a year to run on his Britannia Stadium contract but says the offer of a further year is there as Pulis still has faith in his ability.
"I still have one more year and the gaffer wants to give me another year, but I don't know what will happen," he told the Huddersfield examiner.
"I am not playing games, so maybe I will wait until next summer and see what happens. I don't know what is going on with that, I am just here and want to do well."
However for now the player is staying focused on Huddersfield's promotion push.
"I chose Huddersfield because I know the kind of football the manager wants to play and I know he is fighting for promotion," he added. "My aim is to help the club fight for big things and that means going up."
