I know HRC must approve of the Masters program for those opting in to GRADSO when the time comes to exercise the option. While I haven't found a definitive record of what constitutes an acceptable program, what I have found only points to colleges within the US. There are numerous American-accredited universities overseas with graduate programs that have caught my interest. The opportunity to attend one of them is a real selling point for me. Does one absolutely have to attend a university within the US in conjunction with GRADSO, or are there opportunities to study a broad out there with it that I'm overlooking?
