Your Ohio License to Carry a Concealed Handgun is now recognized in the State of Louisiana, thanks to an agreement signed between the two states. Ohioans now have reciprocity with twenty one states. We need to get PA next.
The agreement is effective immediately. You should remember that the laws of the state you are in is the law that you must follow when armed or you must use deadly force. You must know the law and obey the law of the jurisdiction that you're in.
You can read the signed agreement on the Ohio Attorney General's Website
