First, make sure you have a lot of buddies that will fight for you. Girls at one school are mostly condidered private property. Next: Find out all you can about her and her family and her interests without being invasive. Meaning - if she is a mobster's daughter you don't want to be too inquisitive at certain places. Find a way to run into her in public places and let her see you in your native dress. Sooner or later she will see you and say I "saw you at the such and such last week". Sucess! So ask where she goes to school and ask her out to dinner then (right now) (or later) as you were headed to the place you should should already know she likes to go.
