Illegal immigration to India, most of whom are Muslims from Bangladesh and Myanmar (Rohingya muslims) are a national security risk. There is an organised influx of nearly 40,000 illegal Bangladeshi and Rohingya Muslim immigrants in Delhi who pose a national security risk, threaten the national integration, and alter the demographics. A lawyer Ashwini Upadhyay filed a Public interest litigation (PIL) in the "Supreme Court of India" (SC) to identify and deport these. Responding to this PIL, Delhi Police told the SC in July 2019 that nearly 500 illegal Bangladeshi immigrants have been deported in the preceding 28 months. There are estimated 600,000 to 700,000 illegal Bangladeshi and Rohingya immigrants in National Capital Region (NCR) region specially in the districts of Gurugram, Faridabad, and Nuh (Mewat region), as well as interior villages of Bhiwani and Hisar. Most of them are Muslims who have acquired fake Hindu identity, and under questioning, they pretend to be from West Bengal. In September 2019, the Chief Minister of Haryana, Manohar Lal Khattar announced the implementation of NRC for Haryana by setting up a legal framework under the former judge of the Punjab and Haryana High Court, Justice HS Bhalla for updating NRC which will help in weeding out these illegal immigrants.
