Rio Grande forms some of the border.
I think it is Oregon ============== Although South Dakota's northern border is a little farther north than Oregon's, the answer is actually "Wisconsin." The borders of Michigan and Minnesota converge in Lake Superior south of the International Boundary. The point at which they converge is the northernmost point in Wisconsin, and the northernmost part of a US state that does not share a border with Canada.
russia is the closest country and it does not touch the border of the US!!! :)
Rio Grande forms the Southern border of the United states.
