Another important thing to note about NRC is that it hasn't been tabled yet. It's not clear if the parameters like documents required and the cut-off date will be the same for pan-India NRC.

While NRC is clearly present in BJP's manifesto, there's no clear timeline available for it[1]. The one conducted in Assam took almost six years to prepare and a lot of money (which the Government may not have).
