1. 由Office of Admissions统一受理一切入学申请函件，包括大学部与研究生院；
2. 由Office of the Registrar 受理，权限同1；
3. 由Office of Student Service受理，权限同1；
4. 由Office of Foreign Student Advisor 受理国外学生入学申请函件；
5. 由Office of Foreign Admissions 或Office of International Scholars 受理国外学生入学申请函件；
6. 由Graduate School, Graduate College 或Office of Graduate Studies 受理研究生院的入学申请函件；而Office of Admissions 受理本科部的申请；
7. 由各所属分院（如College of Eng.) 分别受理入学申请信件，也有很多学校先由Office of Admissions 接受申请，供给所需表格，然后一切通信改由各分院负责，大的学校大多采用这种方式，因为他们每年受理的申请函件高达上万件。
有的申请人对所报学校可能不够了解。这样，如果申请读本科，就应写信给Office of Admissions; 如果申请读研究生，就应写信给Office of Graduate Admissions. 这种写法的信件肯定能到达承办人的手中，称呼的方法可采用下列二种方式之一：
