How long take 4 background check/licence

I live in another state and submitted my app. for Mo RN licence. How long does the criminal background take? I read on the Mo BON site that it takes 3 monthes. I'm concerned b/c I've accepted a job, starts in 2 weeks. I read that I cant even get a temp permit in MO till the b/g check is completed. I am licenced as an RN in another state.

What have been your experiences with length of time from submitting all the paperwork until u get the licence?
