You have a typical workers compensation scenario that will require you to get yourself to a workers compensation employee friendly attorney immediately. If you are injured, you cannot be forced to fly or drive to another state simply because the company's corporate headquarters are based there. This is like telling the court that simply because you as an employee got into a car accident while on the job in Illinois, you must use Wisconsin law. It doesn't work that way and I wouldn't fall for it because the employer may come back and say since you are able to travel you are not truly injured.  Further, you might indeed be able to sue your employer for negligence, but watch out because you could have just as easily said no. In other words, try to think from the other side and see what defenses they come up with to deny your claim.  Your lawyer though will be able to help you sort all of this out.
