Manager Derek Adams is determined to make the 32-year-old his first signing of the January transfer window as they look to steer clear of bottom-placed Dundee.
Yndestad, who made over 200 appearances for his former club Tromso in a 12-year spell, is expected to arrive in Dingwall to finalise talks with the club's hierarchy.
The player's agent Roald Oien believes that a deal can be agreed with the Ross-shire club and insists Yndestad is determined to join them.
He told the Daily Record: "Hans Age will travel to Scotland. We look at this as an informal and exciting trip.
"He's going there to get to know the club and to take a medical check.
"We know it's a club we can agree with and Hans Age wants to go."
