Migration has always played an essential role in the history of mankind. At present the intensity of cross- border mobility are much higher than in previous decades. In many countries, children of immigrants constitute a large sector of the population. These children live between two cultures and value systems: those of the parents’ country of origin and of those of the host country. Living between two cultures requires cultural adjustment-referred to as acculturation. Based on carefully targeted survey research, this quantitative study examines acculturation of second-generation Iranians (SGI) in Australia. It examines the interplay between participants’ socio-demographic background, cultural practice, parental versus participants’ cultural preferences, attitudes towards the host nation and cultural acquisition. The results show patterns of biculturalism: while acculturated to the host culture, SGI prefer to maintain aspects of their native culture and tradition.
