Hi laginalandon and welcome to the Chiari forum.
Outside of her moving back to the state she has some form of INS. or getting some for where she is, the only resource I know of is the NIH as they do clinical trials for Chiari.....she would have to look at the NIH site to see what new trials they are welcoming new people to.......
I also want to say how wonderful it is that she has you advocating for her and offering the support so many of us lack.
