Du Plessis was a shining light in Namibia's World Cup campaign and picked up the man-of-the-match award in their Pool D defeat against South Africa.
"I am excited about the challenge and if it is the Lord's will I will end my playing career at Wasps," he told Die Republikein.
"It is every guy's dream to play at a high level. Believe me, I'm going to grab the opportunity with both hands to play with players like Marco Wentzel and other players with international experience.
"It's a privilege to move and carry on your career in such company."
Du Plessis won't join up with the Aviva Premiership outfit until his work permit is cleared.
