With no ride in F1 available after clinching the F2 title, Pourchaire has spent this year as a reserve driver for Sauber while racing in Japan's Super Formula series.
The Frenchman was granted an opportunity to substitute for injured Arrow McLaren driver David Malukas at Long Beach last weekend and performed admirably by finishing 11th after starting 22nd.
Pourchaire hailed the racing as “amazing” at the event's conclusion and has been retained for this weekend’s round at Barber Motorsports Park.
Asked by Autosport if an F1 opportunity did not open whether he would consider a move to IndyCar, Pourchaire replied: “Yeah, sure. IndyCar was already on my list last year.
“It's something I always wanted to do. I didn't have an opportunity to drive.
“I feel like I was also waiting on an F1 drive with Sauber. Unfortunately, I was not able to go to F1.
“There was also the Super Formula, which is a great category. That was also an option for me. I decided to do that.
“IndyCar is great. Why not coming here full-time in the future? It's an option.”
