Ethnic Self-Identification- interesting topic!

It seems there is empirical research going on related to the "Ethnic Self-Identification". Here is are some interesting definitions of four aspects of ethnic self-identification as they apply to first-generation migrants.

"...we assume that there are four two-dimensional possibilities of how people view their ethnic self-identification, as they embrace new or shed old ethnic identities: people can feel integrated, that is they feel strongly connected to both the host and the home country, and the feelings can co-exist; people can feel assimilated,meaning that they completely adapt to the host country and disengage from thecountry of origin; they can feel separated, in the sense that they maintain strong connections to the country of origin and only a weak link with the host country; or they feel marginalized, that is they have loose connections to either the host or thehome country..."

So I guess, my quest is really to ask folks how they were able to either integrate or assimilate successfully and avoid being seperated or feeling marginalized!
