Nationalism and Immigration

Anderson speaks a lot about the "shrunken imaginings of recent history" that have the ability to prompt people to generate "such colossal sacrifices" for their nation. For people to feel such a deep comradeship with the other citizens in their country, they conjure images of a common past--more specifically, a linear, almost fatalistic history that leads directly to the nation's present state. This retrospective historical narrative (though not accurately showing the formation of the nation as confluence of many unrelated events) gives citizens a sense of ownership and longevity within their country, which can stir such strong patriotic feelings as love and the willingness to die.

I'm more interested in how this community deals with immigrants--people who do not share this imagined historical past, but nonetheless have joined the nation in its present form. Can they encompass these immigrants into their concept of nation? Is birth in a nation-state necessary to participate in adopt this imagined recent history? If someone has lived in America for the majority of their life, but were born in the Philippines, is she "American" or "Filipinno"? Can someone inhabit multiple communities at once? How are nations dealing with increasing numbers of immigrants / transnationals? Europe traditionally imagined the Orient as the "Other", the foreign opposite to the Occident, but how must European nations re-conceptualize themselves when large numbers of the "Other" come to live in their country, become citizens, and have children? What are the implications, for example, of South Asians living in England for Anderson's notion of a "deep, horizontal comradeship"?
