My grandmother who is a USC is disabled and would like to have me take care of her. (I am 29 yrs old/unmrd/ not USC). Is there some sort of way to get an immigrant visa so that I can stay and help her here? I know normally you cant immigrate through grandmother but if she is disabled is there some way to immigrate? Or is the only way is to come on a tourist visa and keep extending it (Doesnt seem like good solution to me)
