What do I do if I got into a university but haven't received my I-20 yet?

Long story short, I don’t have a green card yet, and my mom had to change her visa to F-1. My mom’s figuring out a way to get a green card before I turn 21. I basically have to get my own F-1 visa before that, and I don’t have plans to go back to my home country to change my status.

The thing is, I got into a college but haven’t received my I-20 yet. I emailed the international rep about sending the I-20 to my current address about 3 weeks ago. Still haven’t gotten it in the mail. I emailed the international rep about it twice past few days, but I never got a reply. My mom’s planning on going to see the lawyer some time next week.

What do I do? Go to the school and pick it up? College tours are full. It’s little over an hour away, so I don’t feel like driving all the way and back.

Um, call the school.

Better be there in person.
