In guest countries, immigrants typically move to communities populated by their countrymen. In major cities, and even smaller communities, there exist enclaves of immigrants who many times maintain their national language and culture, many times to the exclusion of that of the guest community. An example is Los Angeles' immigrant Latino community. There, many Latino immigrants will live, work, even start businesses without English language skills, or ever assimilating into the mainstream Angeleno community. In fact, a report several years ago had immigrant Latinos responsible for the largest and fastest growing small business sector in L.A.. This is an example of an immigrant subculture.
In France and Sweden, entire towns have been built to house certain immigrants. There, immigrant assimilation into mainstream society is slowed, and the immigrant's indigineous culture flourishes.
