Nimrat, who was roped in to play a Pakistani ISI agent in the international series, was ennobled with a nomination along with the cast of the show in the Outstanding Performance by an Ensemble in a Drama Series category for the Screen Actors Guild Awards 2015.
While the show lost out to "Downton Abbey", Nimrat made her mark at the event's red carpet ceremony.
