The pressure of the admissions process sometimes makes students and parents do things they wouldn’t normally do. One common mistake is for a student who was denied or waitlisted to show up unannounced at the admissions office hoping to meet with someone who read the file.
I understand where that inclination comes from. But it’s almost never a good idea to show up unannounced. And several of my colleagues at Collegewise who worked in admissions relayed that it was not only ineffective, but also a little frustrating, especially when multiple students a day would try it. Frustrating your admissions officer is not a good strategy.
The in-person visit is not likely to change your admissions status. But if you want to know that you gave it your best shot, you could certainly call the admissions office (a parent should never, ever make this call for your student), reiterate your genuine interest in the school, and ask if they encourage or even allow students in your situation to meet personally with an admissions officer. They might say no, but at least you made the call, you were polite, and you asked. If there were any chance to make some admissions headway, that’s a much better route than just showing up unannounced.
