Does it have a vine-y growth habit? The pictures are nice and clear...but don't really show the critical characteristics! To whit: kudzu has compound leaves. Each leaf has three leaflets. The central leaflet is itself lobed, usually with three lobes. Each leaflet on either side of the central leaflet usually have two lobes, although the lobes are not always very pronounced.
So in the #137 picture...that's almost there, but I still can't see what's attached to which.
Another field character are fine fuzzy hairs on the leaf surface. I don't remember if it is just one side or another.
Oh, that hasn't made it into northern New England, as far as I know. I lived in Georgia for a while and witnessed its power!
