Some Rohingya Muslims, living in the country illegally, have fraudulently obtained documents like Aadhaar card, PAN card and even passports, the Rajya Sabha was informed on Wednesday. Union minister of state for home Kiren Rijiju said since illegal immigrants enter the country without valid travel documents in clandestine and surreptitious manners, there is no accurate data regarding the number of such migrants living in the country. “Necessary instructions have been issued to the Unique Identification Authority of India (UIDAI) to ensure that no Aadhaar card is issued to illegal immigrants,” he said in reply to a written question.
