Selin ATAY-TDO-India will conduct a national citizen survey to weed out those living illegally in the country, the government said.
Home Minister Amit Shah said people from all religions who can prove they are Indian citizens will be included in a National Register of Citizens. He did not give a time frame for the survey in the country with 1.3 billion people.
The government's decision is considered as a new step after 1.9 million majority Muslim people living in Assam were excluded from the NRC.
In India, right-wing politicians argue that a list like the NRC, which has sparked debate in the state of Assam, should be removed across the country.
“People from all religions who are Indian citizens will be included. There is no question of any discrimination on the basis of religion,” Shah said in response to concern that his Hindu nationalist-led government might target minority Muslims.
The National Register of citizens (NRC) list included 31.1 million people living in Assam, while 1.9 million people, most of them Muslims, were not included in the list.
Those who cannot find their names on the citizenship list are worried about being recognised as "stateless."
Filippo Grandi, the United Nations High Commissioner for refugees, had called on authorities to "guarantee that no one will remain stateless," taking steps that reduce this risk, avoiding arrest or deportation.
