Missouri agencies and boards that regulate occupations and professions will issue you a temporary courtesy license if you are the qualified nonresident spouse of an active duty service member reassigned to a duty station in Missouri. Every licensing board and commission also has to give active duty military spouses priority when processing applications.
Contact the Missouri licensing board for your profession, ask for a temporary courtesy license as a military spouse, and tell them your application qualifies for priority processing.
