Hi Amanda,
You can offer rotations but you should be clear to the medical students rotating that you do not know the status of your program at this time. Rotations are also for the medical students to gain knowledge and experience through your residency. If you obtain ACGME accreditation between now and the match you should be able to put in a rank order list. The students that rotated will then know your program and that will be a good thing for the students as well as your program.
Hope this helps!
