nursing home expenses

My 86-year-old mother came to the US to visit with a tourist visa. She became sick and the doctor found a mass pressing on her right brain. She is not able to travel home because the cabin pressure in the plane may cause a stroke. There is no cure for her and her doctor does not recommend treatment besides medications to keep her from stroke. My husband and I are caring for her at home with daytime home care. However, we are not able to continue any longer, as she is not getting the best of care at night and weekends. Our goal is to raise  enough money for her first six months' nursing home and medical expenses. She does not have any insurance and is not qualified for Medicare or Medicaid, as she is not a citizen and does not have a green card.  Her tourist visa is being extended so she is the U.S. legally.  Thank you so much, and may God reward you richly in His own way for your generosity and prayers.
