(B) If a person with a handgun permit from another state decides to become a resident of Tennessee, the person must obtain a Tennessee handgun permit within six (6) months of establishing residency in Tennessee. The permit may be issued based on the person having a permit from another state provided the other state has substantially similar permit eligibility requirements as this state. However, if during the six-month period the person applies for a handgun permit in this state and the application is denied, the person shall not be allowed to carry a handgun in this state based upon the other state's permit.
