Between diversity, lost identity?

It is already my third year in America as an international student, but I still wonder what diversity means? Does it mean gathering people from all around the world to a same place? Does it mean sharing knowledge, opinion, and culture from defferent backgrouds? The gap between international and domestic is so huge that I have to bridge language gap, culture gap, even personality gap to get to the other side compeletely. If I go ahead to bridge all the gaps, I certainly will lost part of my identity. But if I don't go ahead and stop at where I am, I can't get to the other side. Walking in the middle of the bridge is what I feel right now.
