MKs tend to be open-minded and tolerant of many diverse cultures. They often feel more at home in culturally rich environments and can be "homesick" for their foreign home. Their knowledge of a country and its culture typically exceeds language fluency. Upon returning to their passport country, MKs possess unique skills that can be helpful to academics and governments. Because of their international experience, they often have a much broader worldview than their peers. This broader worldview can also lead to mixed emotions about their passport country and its foreign policies.
