The correct answer to this question is Nebraska does not have reciprocity, we have a limited recognition.
The difference Reciprocity 2 states form an agreement to recognize each other?s permits, Recognition your state just automatically recognizes another?s without any formal agreements needed (ours is limited due to the fact that rather than recognizing all permits, like Missouri, we recognize those "similar" to ours). If another state wishes to recognize ours due to the fact that we recognize theirs (Colorado, has this type system) if we see they work that way we can inform them of the recognition and they can verify with the NSP.
The advantage of recognition is it is a step toward full national recognition like is done with drivers licenses. There is no formal contract in place, states know that all states have similar requirements and just automatically recognize each other?s licenses.
