Two logistical issues may arise if you are wait listed at one or more of your preferred schools:
The first logistical issue relates to seat deposits. Applicants usually remain on a wait list long after the seat deposit deadlines have passed at the other schools where the applicants were accepted. So if you are wait listed at School A, you will need to decide whether there is a School B you would be willing to attend if you aren’t admitted at School A or whether you will wait and apply again to School A the following application cycle. If you are sure that you want to attend law school the upcoming fall regardless of whether you are admitted from the wait list at School A, then submit a seat deposit at School B. This is a common practice, and it raises no ethical issues if you get off the wait list at School A and decide to attend there instead. The only drawback to placing a seat deposit at School B is that you may lose the deposit if you get off the wait list at School A because not all schools refund seat deposits.
The second logistical issue arises if Schools A and B are in different cities. If you are still on the wait list at School A in August, you will likely need to sign a contract for housing near School B. If you do so, be conscious of any penalty clauses for breaking that contract, a necessary step if you are later admitted off the wait list at School A. You would also need to arrange to move your belongings quickly.
