Kuala Lumpur is one of the tourism destinations which offers a balance of historical and modern development. It has become a central meeting place for the immigrants who monopolised the business operation. This study examines and analyses the perception and opinion of tourists visiting Kuala Lumpur towards the immigrants' influx in the heritage zone. The variables are categorised into three; demographic characteristics of the tourists; tourists' perception and opinion towards the immigrant influx; and tourists’ perception and opinion towards heritage conservation and value. The finding helps the stakeholders to formulate a policy in controlling the immigrant influx in Kuala Lumpur.
