I am a Malaysian and I have a 81 years old, US citizenship aunty staying alone in US and needs care from me. My aunty is staying at US. She does not have any child and her husband just passed away. There is no one who can take care of her. We have actually discussed on this and she would like me to move there and stay with her so that I can take care of her. However, I am a Malaysian and I do not have any green card/ visa to stay in US. Can I get guardianship for her? If yes, will I be able to stay in US with her?
