Acculturation strategy has been an integral and essential part in the field of acculturation study. The fact that an increasing number of international overseas students wave into China renders this research urgently in need; and new theoretical models emerged constantly, which have had a significant effect on the immigration policies in China. This paper, based on the exemplification of the significance of acculturation study, aims to display the setting, clarify such three frequently confusing terms as adaptation, acculturation, adjustment by comparing and contrasting the similarities and differences before fixing the acculturation as this study's preference, then presents a brief but clear description of the history, dimensions, and subjects of acculturation study, and finally discuss two kinds of acculturation modes, four acculturation strategies in particular held by John Berry: assimilation, separation, integration, and marginalization.
