Explanation:

Besides migration caused by displacement, there is also a large and continual unregulated movement between Assam and neighboring regions of Bangladesh with an exceptionally porous border. The situation is called a risk to Assam's as well as India's security. The continual illegal entry of people into Assam, mostly from Bangladesh, has caused economic upheaval and social and political unrest. During the Assam Movement (1979–1985), the All Assam Students Union (AASU) and others demanded that government stop the influx of immigrants and deport those who had already settled. During this period, 855 people (the AASU says 860) died in various conflicts with migrants and police. The 1983 Illegal Migrants (Determination by Tribunal) Act, applied only to Assam, decreed that any person who entered the Assam after Bangladesh declared independence from Pakistan in 1971 and without authorisation or travel documents is to be considered a foreigner, with the decision on foreigner status to be carried out by designated tribunals. In 1985, the Indian Government and leaders of the agitation signed the Assam accord to settle the conflict.
