This document outlines a proposed Cultural Transition Development Theory for international students studying in the United States. The theory consists of 4 stages: 1) Needs vs. Opportunity, where students identify opportunities in the US and intend to act; 2) Research, where students select a school and make plans; 3) Conflict, where language, cultural, and social barriers lead to shock as reality differs from expectations; and 4) Integration, where students begin to integrate new ideas and aspects of culture into their identity. The document provides examples from interviews of international students' experiences that illustrate stages of the theory. It identifies limitations and proposes future research such as a longitudinal study.
