Visiting students are ‘undeclared’ for their program of study. Registration must be mailed or submitted in person. Your registration will not be processed until the Letter of Permission (LOP) from your home institution is received. The deadline for registering for courses is the 20th of the preceding month, so the deadline for a course that starts November 1 would be October 20. As your registration will be held until the LOP is received at ACC, please allow enough time for your home institution to process the LOP prior to the registration deadline.
