Mo. Rev. Stat. § 302.063
The department of revenue shall not issue any driver's license to an illegal alien nor to any person who cannot prove his or her lawful presence pursuant to the provisions of this chapter and the regulations promulgated thereunder. A driver's license issued to an illegal alien in another state shall not be honored by the state of Missouri and the department of revenue for any purpose. The state of Missouri hereby declares that granting driver's licenses to illegal aliens is repugnant to the public policy of Missouri and therefore Missouri shall not extend full faith and credit to out-of-state driver's licenses issued to illegal aliens. As used in this section, the term "illegal alien" shall mean an alien who is not lawfully present in the United States, according to the terms of 8 U.S.C. Section 1101, et seq.
