Answer: "Third" wave immigrants came mostly from South and East of Europe.
Explanation:
"Third" wave of immigration, which took place roughly between 1850 and 1930, originated from Southern and Eastern Europe. It is estimated that approximately 25 million people arrived during that period, with a large number of Italian immigrants (mostly Catholics) and many nationalities of Eastern Europe, including Poland, Hungary, Romania, Czechoslovakia, Russia and Baltic nations.
