Help my brave old mom from Ukraine who escaped war

My brave old mom, 74 years old, is from Ukraine, where she was living peacefully with her husband until the Russian invasion. Her biggest challenge in life is Parkinson Disease - even if she is brave inside, this disease has made her weak outside. She was forced to leave her home in Zaporizhzhia with her husband because of the Russian invasion, and spent many hours to get to the Polish border to be safe in a refugee camp. Her big motivation is she wanted her husband to get to a safe place away from the war. With a visitor visa, they had a chance get to the USA, and now my sister has kindly taken them to her home. Unfortunately, their visa type does not allow them to apply for government assistance, especially medical insurance. She has run out of her Parkinson Disease pills - this is critical for her to continue to live. We are fundraising money to provide her medical assistance that will give to her the opportunity to live her life in a safe place surrounded by family. Will you please help?
