Immigrant Experience in Tropic of Orange

In almost every book we've read this semester there seems to always be a character, or characters, who struggle with identity or sense of who they are. After reading the first section of The Tropic of Orange, 
I once again saw a struggle for identity in the section on Bobby. Although Bobby is 100% Chinese, he represents an interesting early theme of the novel: melding of culture. I thought the fact that Bobby had to pretend to be Vietnamese in order to come to America, speaks Spanish, and lives in "Koreatown"is an interesting way to set up a sort of shared immigrant, or non-american, experience in this novel. The section on Bobby seems to ask the question, "how do we really see others?" This sort of mixing of identities for Bobby made me feel as if the book sets up Immigrants as it's own conglomerate cultural identity. I don't necessarily think this creating strips immigrants of their individual identities, but rather creates a sense of community and togetherness amongst those who share in the immigrant experience. The proud tone of Bobby's section suggests that the man's mixing of cultures is something to be revered and acknowledged as admirable.
