Born under the British rule, Sushil Burman was a child when India achieved Independence and then went through a messy partition. In 1956, he and his father fled from Mymensingh in East Pakistan -- now Bangladesh -- for fear of religious persecution. "I was still a child when the partition happened, and riots broke out all around. We came to India because my father believed it was not safe for Hindus in East Pakistan anymore," says Sushil Burman, now a 75-year-old man excluded from the National Register of Citizens (NRC).
