F-1 Visa Process

Hi everyone, I’m an international student living in the United States who is going to attend Penn State University this fall. I’m currently a senior and looking to change my F-2 visa to F-1 visa to attend the university.
I followed the instructions for the I-20 application and its in process of being either approved or rejected.
I was wondering if anybody knows how the F-2 Visa to F-1 visa process lasts? I would like to get it done early but I’ve heard it takes a while and it might not come before the beginning of fall semester, which means I can’t attend the university.

Someone please help?

If I remember it right, you may attend the school as long as you have an I-20 and you entered the US legally. You need the current visa for re-entry.

Yea, I entered the U.S 10 years ago and my parents have been switching F-1 Visas and two of us have been F-2.
