well if you meant to say that Pakistani actors are discriminated against in India then you are wrong. if you want to go in to a highly competitive industry where people are ready to cut your throat for little success then you will have to face all these problems.
Same thing happens with every star , be it big or small.
If India didnt like them then they wouldnt be working in India.

India has always supported Pakistani artists and welcomed them with open heart. just listen to any of their interviews. they are full of praises about India.
Bollywood attracts people of many nationalities in a small but significant number. But only Pakistanis get special treatment.
