Here is info about the Nursing Licensure Compact:
https://www.ncsbn.org/158.htm
If your home state is a member of the compact, the other compact states will recognize your home license and you can work in those states without having to apply for another license.
As you can see from the map and list at the website, IN, MI, and OH are
not currently members of the compact. However, if you have a valid/active IN license and want to work in OH or MI, you can simply apply to the OH or MI BON (or both!) for a license in that state. You can be licensed in as many states as you wish (provided you meet their requirements and pay the fees).
Since the endorsement process typically takes some time, if you think you want to work in OH this summer, it would be smart to go ahead and apply now, so you can have a license in hand by summer. I'm sure the OH BON website has all the info you need for how to apply for licensure "by endorsement" (that's the term for when you are already licensed in one state and want to get a license in another).
