Hi pre-opt:
I did a bit of research (some free time since I'm recovering from laryngitis), and this is what I found for Missouri.
Missouri Board of Optometry:

Missouri requires two sets of fingerprints for a background check. If you want to do it digitally, you go through Identix (contact info on the application) which is $52 (plus any other processing fee). Digitally takes 2-3 weeks for processing. If you want to submit paper and ink fingerprints, you need to use the fingerprint cards through the Board and that cost $39.25 (3-4 weeks to process).
An official transcript is needed for the application. I interviewed at two places and neither asked for my transcript.
Read through the part that says "Certification of Optometrists to use Pharmaceutical Agents":

Unless it's different in Missouri than California, it's illegal for you to practice without your state license. Take the free time to visit the local societies and start inquiring who is looking for an associate and/or partner and what the typical per diem rate is for your area.
