BTW, IIRC, from my own university boxing days, you have to have a boxing coach's signature as well as a physical exam and be in both good academic AND conduct standing at your school.
For non students, check the ABA (Amateur Boxing Association).
The U.S. Amateur Boxing Federation. Golden Gloves Competitors. Sparred a bunch of them as a teen in Takoma Langley Community Center near DC. Good group. PEACE
