The application for the LL.M. class beginning in August 2017 will open in September 2016. The application deadline for the LL.M. class beginning in August 2017 will be December 1, 2016, at 11:59 p.m., U.S. Eastern time.
In addition to submitting the online LL.M. application by the deadline, applicants must make sure that any other required documents (e.g., transcripts, TOEFL results) are sent out in time for delivery to our office on or before the deadline.

出願締め切り日に直前にTOEFLを受験し、締め切り日後にスコアの差し替えをリクエストするケースも時としてあります、スクール側として、そうしたリクエストには応じない姿勢が読み取れます。
