There are a lot of things that you can do to impress a foreign student. You can try to act normal around her. Enlightening her about the culture of your country will also go a long way. You can also show her some of the basic places and assist her to get settled in.
The same way you impress anyone else, but a little more redneck. My Japanese exchange students loved anything American. This makes cheap dates optimal. Take them to some hick-ass hotdog stand, they would get more out of it than from some sausage place. Exploit your American-ness.
