He then attended Temple University, where he received a Master of Fine Arts in Acting.

After graduating, Nayyar found work doing American television ads and plays on the London stage. He first gained attention in the US for his role in the West Coast production of Rajiv Joseph's 2006 play Huck & Holden where he portrayed an Indian exchange student anxious to experience American culture before returning home. In 2006, Nayyar teamed up with Arun Das to write the play Cotton Candy, which premiered in New Delhi to positive reviews.

His agent heard about a role for a scientist in an upcoming CBS pilot and encouraged him to audition for the part. This led to his casting in the sitcom The Big Bang Theory, on which he plays astrophysicist Rajesh Koothrappali.
