I could be wrong, but I got this from the book "Asset Protection" by Adkisson and Riser (well known attorneys in this area): Under state law, having a registered agent in the state of incorporation creates nexus sufficient to allow the corporation to be sued in that state. This fact alone may affect the decision where to incorporate. A jurisdiction where jury verdicts tend to be very conservative may be preferable to one with a reputation for runaway jury awards. The cost of defending a lawsuit may also be a significant factor in this decision. Defending a lawsuit in the owner's home state will be substantially cheaper than defending the same lawsuit across the continent [or as one person here says, across the world]. This may be a factor in deciding where to incorporate And you can always be sued in the state in which you are operating. So it seems that you can be sued in both states.
