The Assam government has tightened security across the state ahead of the publication of National Register of Citizens (NRC) on August 31. The Union government is also reviewing the state's preparedness to handle the law and order issue that might arise as reaction from those left out of the NRC.

The NRC is a list of all citizens domiciled in Assam and is being updated at present to retain bonafide citizens within the state and evict illegal settlers, purportedly migrants from Bangladesh. At present, the list is being updated - for the first time since 1951 - by the Registrar General of India in a Supreme Court-monitored exercise.
