Register for Courses

Step 4: Plan your schedule
View the Schedule of Classes to search for courses and plan your schedule. Most courses are open to visiting guest students, though some may be restricted to degree-seeking students. Take note of any courses with pre-requisites, as you may need special permission from the instructor in order to register.

Once your petition has been approved by the University Registrar's Office, you may log into Student Information Online (SIO) to search for courses and organize your schedule.  

Step 5: Register in SIO
Visiting guest students do not have specific registration start times and are not able to register for courses until after Registration Week ends (see Academic Calendar for exact dates).

If you are unable to register for a course because of pre-requisites, email the instructor for permission. If permission is granted, forward the reply to and you will be registered for the course. 

If you are interested in a course with a pre-existing waitlist, please be aware that you will be placed at the end of the waitlist, as preference is given to degree-seeking students. You can learn more about the waitlist process and timeline by viewing the Waitlist Navigation Guide.

You can learn more about course registration on the 4 Easy Steps to Registration webpage. Students registering for Tepper School of Business courses follow a separate process.

Follow the Academic Calendar 

Step 6: Follow the Academic Calendar
Visiting guest students are subject to all dates and deadlines listed on the Academic Calendar. It is important to familiarize yourself with the Academic Calendar for the semester or academic year in which you are enrolled so that you do not miss important dates and deadlines.

If you decide to drop a course and would like your tuition adjusted, you must to do so before the course add/drop deadline to receive a tuition adjustment (see the Academic Calendar for dates). Tuition for courses dropped after the course drop deadline to receive a tuition adjustment is not adjusted unless a tuition adjustment request is approved.

If you decide to drop a course later in the semester, you must do so by the drop deadline for full semester courses or by the mini-course drop deadline, depending on which courses you are taking (refer to the Academic Calendar for dates). Visiting guest students do not receive Drop Vouchers. 

You can learn more about course adds, drops, and withdrawals on the Course Changes webpage. 

Student Visas

If you are an international student interested in becoming a visiting guest student, you must already have a valid visa to study in the U.S. in order to apply. Unfortunately, Carnegie Mellon is not able to issue student immigration documents to Visiting Guest Students.
