You can maintain as many licenses as you are willing to pay to maintain. In other words, you can be licensed in Oklahoma as well as Kansas. What you would need to do is endorse your Oklahoma license into Kansas through a process called 'Licensure By Endorsement.' Endorsing a license takes time, so be sure to start the process several weeks before you move to your new state of residence.
You can go to the Kansas BON website and download their application for licensure by endorsement.
