Many Indian student who go to US do not mix with the society or tend to isolate themselves, or the socialize with other Indians only. Acutally there is no inter- intra presonnel relationship with other people of differnt nationlites, this tend to create a deep division within the students community.
Our students tend to look down on other student who are not par with them and expecailly for the Brahmin student there is spirit of competion which the white folks dont like. The Indians stduent try to put Zalra to thier professors, which irritates th other people.Indian student are bothered about others affairs white folks are not intersted.
Especailly people from Andhra pradesh do not have the basic desecny and they do not have any civic manners these could be the plausible reasons .
