Definitely don’t worry about not being able to visit Boston College. They will never know that you weren’t there. I just took my daughter there to visit and while they ask that you register for your visit on their website (which you do so that they can send you an email with directions, etc.) they do not even have you sign in when you arrive for the information session and tour. They flat out tell you that they do not track “interest” as evidenced by visits and other interactions with the admissions office and that it has absolutely no impact on the decision process. If you are interested in Boston College, save the visit for accepted students day (after you are accepted and know whether it is economically feasible for you to attend or not). Good luck!
