Thought I would give some info on my recent experience soliciting fee waivers.
Chicago:
According to the link this is their policy "The Law School will also send out additional fee waivers to applicants based upon data from the Candidate Referral Service (CRS) and in conjunction with various recruiting events. The Law School is unable to consider individual Fee waiver requests."
Virginia: Success (as many on here have already noted)
University of Washington:
Thank you for your message and interest in UW School of Law. Attached you will find the fee waiver application form. Please read the form carefully and email or fax the completed form along with your supporting documentation to our office after October 1. We cannot accept fee waiver applications before that time. Should you be granted a fee waiver, we will email you with the fee waiver code.
Please feel free to contact our office should you have any questions.
The form says that they will consider offering a fee waiver to "Applicants with a GPA and/or an LSAT score at or above our medians"
I did not solicit waivers from GULC, Cornell, Duke, or Michigan because I received unsolicited waivers. I have yet to solicit waivers from Columbia/Northwestern/NYU/Penn because I am not sure if I will apply to those schools.
