I want to backup what Mango said about establishing residency.
It can be very complicated, depending on the state. If its just living in the state for 1 year and getting drivers license and tags switched over, then thats a pretty good deal in order to achieve residency.
Compare Ohio's situation to Texas, where you have to live and work in the state for a full year WITHOUT GOING TO SCHOOL fulltime to establish residency. Consider the following (hypothetical) situation: Let's say I were to be a full time student at a Texas university for 5 years. I change my drivers license, tags, and registration over to Texas my first semester. I vote in all local and national elections as a registered voter in a Texas county. I am independent of my parents financially and submit my tax returns independently from them. Lets say I also work a part time job for all of those 5 years. Now, what does all that get me?? NOTHING. I'm STILL not a Texas resident even after going through all that. Unless I were to drop below full time for a full year, I STILL would not be a Texas resident even if I stayed in college for 10 years. That makes it much harder for an out of stater unless they are nontrad to become a Texan, but hell they ARE Texas so I guess they have to keep their standards up
Okay, I'm done ranting about Texas.
The tax situation is also well noted by Mango. Depending on your finances it might not be worth it just to get residency status.
I'm not sure what the standards for Oklahoma residency are. In the end, going to Ohio over Oklahoma won't give you a significant edge, but it might give you a little bit of an advantage. OU (Univ. of Oklahoma) typically has a very high instate acceptance rate compared to some other programs. I believe its close to 50% now. Most of the Ohio programs are lower than that, but then again there are 5 more of them so that makes up the difference perhaps, whereas OU is your only shot for an MD program. Of course, Ohio probably has 5X the population of Oklahoma as well, if not more.
I think there is also just one DO program in Oklahoma (at Oklahoma State Univ. in Stillwater) but I'm not sure about that.
Good luck, wherever you decide to go.
