This is a hypothetical question for right now, but definitely something that might occur in the future. Since obtaining citizenship I am of course eligible to sponsor my mother for a GC. She lives happily in Europe with my Stepdad and is in her late 50s. I was wondering what if something happened to my Stepdad and she decided she would like to come live with her only daughter in the US? My biggest concern is health insurance? Does anyone have any experience or information?
