About how many european immigrants were processed at the facilities on ellis island? 2 million 12 million 50 million 60 million

The answer is 12 million.  Many of these immigrants came to America in the hopes of making a better life for themselves and their families.  Eventually their descendants have integrated themselves in American society.  Many have become successful and so have their descendants.  Even today, despite the economic problems in the U.S., people still want to travel there to achieve the same success as early immigrants did so many years ago.
