Many faculty will tell you to not be choosy about geographic location but remember that you will spend three years in law school and may develop professional connections that translate into a job after graduation. Be aware of your own preferences and don't be afraid to let them guide you as you consider law schools.
Law school is never cheap. Some schools are cheaper and some offer scholarships and other aid. While you will not receive information about scholarships before you are accepted, some schools are more vocal about the aid they provide to typical students.
Can you get in? Do your stats match the stated requirement? Don't limit yourself to schools that are a safe bet, but be sure that some of your choices are realistic.
Who are the faculty? What are their areas of expertise? Are they distinguished? Are they all about to retire? Do they publish with students? Can you see yourself working any of them, preferably more than one?
Look for information about job placement rate and the percentages of graduates who move on to careers in what you think might be your chosen field
