Marius Niculae is free to play for Inverness Caley after the Romanian won his work permit on appeal yesterday.
Niculae said: "I can now concentrate on doing my best for the club and I can't wait to pull on the jersey.
"I hope to repay them with goals for Caley Thistle. I feel fit and raring to go now and I hope I can play a part soon."
Alan Savage, the Caley Thistle chairman, said: "We felt we had a very good hearing but were told to go away and await a decision within two hours.
"As you could imagine, that was a very nail-biting period as we waited on the outcome. But all our efforts have been worthwhile."
