Effective January 10, 2016, people using a driver's license from the states of Illinois, Minnesota, Missouri, New Mexico or Washington will have to use another approved form of identification in order to enter West Point and all other military installations. If you possess a valid Department of Defense issued identification card this new requirement does not affect your ability to enter military installations.
Acceptable alternate forms of identification are a US passport, a permanent resident card/ Alien Registration Receipt Card (form 1-551), a foreign passport with a temporary I-551 stamp or visa or an employment authorization document that contains a photograph (Form I-766).
Visit the Homeland Security website more information on the new requirement.
