That's a great idea Cookie!! I think I'm going to do that for KSU sometime soon... I know at the orientation during the interviews, he said that it was absolutely NOT possible to gain residency when you come in as an OOS student. But I don't know...?! That's kind of all he said about it and I hope that really isn't set in concrete.
I feel your desire, because I sure have it too... From what I understand, it's very difficult to gain residency status with the CVM (state, CVM, whomever). Kansas has a really long document online (state government document) - and they are soo specific. Like, you can't just "work" or have a job to do it. They define what types of work, and if it's work that a student might have (waiter/waitress, for instance) it doesn't count. In fact, I think either it, or the CVM, flat-out says, if you came here initially with the purpose of school, you ain't gettin' it.
Now, if your spouse comes there, and works for K-State, I believe, at least for my class, you could get in-state tuition. I heard second-hand that THAT may be impossible for future classes. If your spouse comes to KS and works for some other employer, I think that doesn't count - but again, don't quote me.
Put bluntly, regarding KSU, they rely on our 50% of the OOSers in the class for the $. So whether by fact, or by design, it is very hard to switch.
At the end of my interview, one of my interviewers proposed that I move to KS, establish residency, and re-apply the following cycle, to save $. Obviously, I didn't do that, but in retrospect, it really isn't a bad idea. One year of your life in exchange for saving thousands in tuition (loans)?
But, anyway, off the tangent. If you find a way, great, and, let me know how you did it, if you ever do.
