What, in general, do people in Ukraine think of Americans and our culture?

My son is engaged to a girl from Ukraine and is in the process of obtaining a fiance visa for her. She is a little unsure of herself as far as her English but seems to understand the language well. This being as it is, and the fact that she is very quiet make it hard to get to know her. I wish I knew more about her country, their customs and culture etc. Can anyone give me any insight into what it must be like for her to be planning on a move away from Ukraine to come live here?
