Yeah for all of us - most of us are descendents of immigrants, but we're Americans. My grandfather's parents immigrated from Bavaria and Switzerland. They learned English, but they spoke both German and English in their home. My grandfather refused to speak German to his children, so they learned only English. Going 'full circle' so to speak, my family lived in Germany for 4 years, where my children learned German from neighborhood children. They were in an American school because the German schools only had a month of summer vacation, and we were there to TRAVEL as much as possible. In college, they both SAILED through German language classes.
As far as I'm concerned, Americans would do well to actually learn to SPEAK more than 1 language. We're just about the only country in the world that's arrogant enough to think everyone else should learn our language while we don't require our kids to be able to speak a foreign language when they graduate from high school.
