Are reciprocity agreements between states bi-directional or do you have to be a resident of a particular one of the two states to take advantage of them?
I've seen Arizona list several states as ones that they have agreements with, but those states don't seem to list Arizona as one that they have agreements with. So do you have to be a resident of State Z making money in State X to take advantage of the agreement or can someone be a resident of State X and make money in State Z to take advantage of the agreement?
