In order to register to vote in Nebraska, you must:
You can register in the county you are attending college if that is the place in which you intend to establish a home and be habitually present. Leaving for temporary purposes, such as college attendance, need not result in a change of residence for voting purposes. If you are a Nebraska resident, you can register with the election office in your home county even if that is in a different county than the one you attend college. Likewise, if you live in a state outside Nebraska, you can vote in your home state. Declaring your residency in Nebraska does not change your residency for tuition purposes.
