ckd816- Just to clarify: WICHE funding does not create any obligation to actually practice in your resident state after school. The whole point of WICHE is that some states do not have vet schools (like my home state, Wyoming). The state recognizes that there is no IS option for its residents, so it agrees to sponsor a certain number of students each year to attend school in neighboring states. The state does this so that residents have a chance to get IS funding. They hope you return to practice in Wyoming, but there is absolutely NO OBLIGATION. You do not have to repay them.
This is not unique to vet schools. The state will also fund M.D. and dental students, as well as undergrads through WUE (Western Undergraduate Exchange). None of these programs includes an obligation to work in the sponsoring state.
You may be thinking of the Federal progam where you can work in a rural community in exchange for loan repayment (one year repayment for each year worked).
If you are in a WICHE state (includes WY, MT, ID, UT and Alaska) apply as WICHE! It can help you get in as well- WSU, OSU and CSU all offer a set number of WICHE spots each year depending on how many the other states are willing to pay for. I am attending CSU as a WICHE sponsored student, and I think that my WICHE sponsorship helped me get accepted. Yay WICHE!
