Where is LZ located? If it's possible for you to visit, I think it's better to do that for 2 reasons: 1. get to know more about the school, program, professors and current students, so you can have a better knowledge of whether you and the school fit each other. 2. show your interest at the school.
If it's too much trouble for you to visit, you'd better talk to the school and request an off-site interview.
