Many Japanese go to America and some return and some do not.

I think America is a good place for challengers. The father of my friend went to America long time ago from europe with a very small money in his pocket. He worked hard and finally became a doctor. It was a dream-come-true for him which he could not make it in his home land.

If you are in Japan, you do not think about racial prejudices, but if you go to America, you are a minority group. A difficult problem waits you.
