@Empire007 very true, it is known fact that it takes 3 generations to blend a.k.a Americanized. When a community blends w/o loosing their roots, values survives for centuries (again Jewish community that I had no knowledge of until immigrated here), others loose the identity and potentially falls into dark side of America. Also believe that immigrants have better perspective of world (especially those who immigrated based on qualifications) as they have experience multi culture society, values differences and tend to adopt good things of a nation they immigrated to and leave behind dark side of that nation and therefore contributing to their offspring success and nation.
Healthcare industry being 16~17% of GDP, had created an humongous choices that a typical immigrant had never experienced nor thought of.
