The Bill seeks to make illegal migrants of certain minority communities from Afghanistan, Bangladesh and Pakistan eligible for the Indian citizenship.
In a press statement, the PRISM said the executive committee meeting of the body yesterday decided to involve all political parties and NGOs of the state in protesting against the proposed legislation.
"The Bill, if passed, would cause serious demographic crisis in India. It will affect those regions in the northeast which share international border with Bangladesh, Nepal and Myanmar," the statement said.
PRISM expressed apprehension that illegal immigrants from Bangladesh in western parts of Mizoram would be granted citizenship if the proposed bill becomes a law.
