I'm writing an essay, but I'm stuck on coming up with names for types of identity for a person who's integrating/assimilating into a different culture/country. I'm not sure what words to use to name his/her identities as an individual before and after the assimilation. Ethnic identity vs. mainstream identity? private vs. public? primary vs. secondary? They have to imply a transformation from one to the other. Could somebody help me? Thank you.
