Since then, the bill has faced tremendous opposition by student and political organizations and has led to a number of agitations in the north east states
PM Narendra Modi, who started a tour of the North East India on 9th February, 2019, was shown black flags by protesters in at least two places in Assam.
The bill was first introduced by the Lok Sabha on 19 July, 2016.
It aims to grant citizenship to non-muslim minority communities.
They are primarily Hindus, Sikhs, Jains, Buddhists, Parsis and Christians from Afghanistan, Pakistan and Bangladesh.
This is quite different from the Citizenship Act of 1955 that label a person an “illegal immigrant" if he or she has entered India without travel documents.
Assamese organizations say that as a result of the bill the burden of illegal migrants will be passed on to the state alone.
Also, Protesters believe the bill will destroy the language, culture and identity of assam
The centre says the amendment is for migrants who came through the eastern and western borders and are staying in India.
The burden will be shared by the entire country, with the centre willing to help to implement it.
However, PM in his speech in Assam said that Misinformation is being Being Spread Over Citizenship Bill.
He added that there is no room for "intruders" in Assam as well as the country.
