Yes! You certainly can learn Norwegian "over here."
My minor was called Scandinavian Studies, and I went to school at a place called Concordia College in Moorhead, Minnesota. Our school was founded in 1894 or so by Norwegian immigrants.
My ancestory is 3/4 Norwegian, and the other 1/4 is Irish and a mix of other things. One of my relatives, Knut Nelson, was the first Norwegian to be a senator in Minnesota.
I've always been proud of my Norwegian ancestory, and with our college having a foreign language requirement, it was only natural that I learn a language that was near and dear to the family. Both grandmothers and one grandfather spoke the language. In fact, the grandfather who I never knew grew up speaking Norwegian in America, and learned English as his second language!
So...that's the story. I still haven't visited your country. Some day when I find the right economical way to do it, I certainly will. I almost came over on a study abroad program during college, and then our plan fell through at the last minute. What a disappointment!
