I think the best solution would be to implement Visa system for Mumbai. All ppl who are not domiciled in Maharashtra must apply for visa(Business/Personal/Work/Socail Visit). This the only way to control the influx of non-deserving, uncivilised,blue collared vandals from other lawless states in India.This can be modelled on HongKong Visa System as it applies to mainland chinese. Else the dream of putting Mumbai on World map rubbing shoulders with likes of Singapore, HK, Tokyo or Shanghai remains a distant dream. - Ek Marathi Manus
