I was 家裡移民, too. I came to USA when I was 15. I lived in a small island "Maui" in Hawaii. In Maui, total people who can understand Chinese were only 100 people or less. Of course, in my school, (I was in high school), nobody can speak Chinese to me. Actually, I was the only one who can't speak English. At that time, it was so hard for me.
I cried almost everyday, because I had so many friends when I was in TW, but when I came to Maui, I had no friend at all, and I don't speak English at all. Nobody want to talk to me, actually I don't want to talk to anyone.
However, i have been to Hawaii for 6 years. I already get used to this place. In fact, I don't like to live in Taiwan.
what I want to tell you is... it's VERY hard at beginning, but... that's okay.. take it easy... ^_^
