Even the north easterner (tribal and non tribal alike) like myself can’t settle in those places. The point is Assam is connecting state and one who controls it , control the entire N.E.
Assam is a heterogenous state consisting of indigenous people and people from North India who settled here in ancient time and assimilated in local population or rather I should say created a unique culture prevalent in the modern time. If citizenship bill is amended, majority of BDeshi are likely to settle in Assam turning it into a majority Bengali state like Tripura with local losing the control and also loss of indeginous culture , language and its identity itself which is what happened in Tripura where now Bengali is majority language and hardly any local speaking local Tripuri language. If Assam fall, entire northeast will fall.
