This paper focuses on an ongoing international collaboration between two large public universities, one in the US and one in Mexico, through projects in program development, faculty exchange, graduate student/teacher field experiences, student mentoring and joint research in the area of a foreign/second language teaching and teacher development. Insights from the literature on higher education collaboration and teacher exchange are presented, along with an analysis of the characteristics and conditions that have contributed to this particular network of collaborations over a ten-year period from 2004-2014 and still continues today. Consideration is given to ways in which collaborating across diverse cultures is complex and how networks can contribute to teacher learning. We conclude with implications for collaboration, especially in intercultural teacher education, among diverse higher education participants across geopolitical and cultural boundaries.
