This piece says that Shahid along with his brother and two sisters were living in the U.S.A. Not just they but also many Indians today move to abroad for various reasons like education, job or any other purpose. They meet each other every now and then over there. The Indian diaspora is comparatively large than any other country. In this piece, we can see that though Shahid had migrated to abroad, he spends every summer in Srinagar, which means that they love their mother-land and never forgot it.
